The benefits of stainless steel braided PTFE lines are that they have a longer life-cycle with a not stick liner which is ideal for process and automation, filling machines and solvent transfer lines. 

Benefits of the stainless steel hoses are:

  •  Full Vacuum Rated
  •  Easily Drainable
  •  Higher Flexibility
  •  Can be sterilized and autoclaved

Generally, these hoses are durable and can be used for many different types of applications. 


Procuring Food Grade Water Hose for Production

1.5 inch Convoluted PTFE Hose wThere are certain regulations and sanitary guidelines that anyone who grows or produces food for human consumption must follow. One of these are making sure that a food grade hose is used to transfer any liquids or solids to food for human consumption.

The standards that are put in place for use of a food grade hose are  to prevent many things. There are a number of factors that could contaminate food or water source, such as leaks, contamination or rust. These things could potentially discolor food or even leave it with a rubber taste from the hose. Every part of these hoses must meet food safety standards and go through the highest quality testing to ensure that it can be labeled for this particular use.

There are various uses for these hoses. Some of the more common uses include the transfer of a variety of liquids such as milk, juice or soft drinks, all of which require an FDA approved food grade water hose. Many dry bulk products can also be suctioned through a hose like this. The average consumer has no idea that most of these regulations exist, or that only certain materials actually meet these regulations. PTFE Hose assemblies are ideal for these types of applications.

A buyer can purchase full range of food grade hoses like this from any number of distributors. Supply stores may carry them and there are several online distributors that also deal in a range of products. Anyone buying would just need to know what type of hose they actually need and then compare prices and figure out who carries the product that will work best for them. Taking the time to purchase the right fluid transfer products now can potentially save a lot of trouble down the road. It would be the right step to take out a bit of extra time and ensure that the right equipment and the right hose assemblies are purchased.

Make Sure You Have the Right Chemical Hose for Your Project

You have heard it before – quality and upkeep of chemical hoses are critical to the safety and efficiency of your manufacturing facility. However, the unfortunate truth is that sometimes corners are cut in an effort to save month or time, or both. This puts both your plant and people are great risk to chemical exposure, not to mention production downtime and lost revenue. Checking your chemical hose compatibility, regular maintenance, and a trustworthy chemical hose supplier are the key elements to providing a safe and productive work environment.

Though a variety of chemical hoses are designed to deal with especially harsh chemical transfers while remaining resistant to abrasion and mild external chemicals, it is important to ensure your chemical hose is compatible with the materials used in your manufacturing. That’s why FlexFit Hose developed this chemical hose compatibility tool. It is advisable to test the hose tube prior to any application where dangerous products are concerned because the integrity of those hoses depend on how they were manufactured, and that you are using the proper chemical hose for your needs.

In 2010, reported that a worker at a DuPort plant in West Virginia was exposed to the chemical phosgene, linked to a chemical hose that showed signs of fraying. Upon investigation, it was determined that the tragedy was the result of a series of equipment failures including poor maintenance, inadequate provisions for handling toxic materials, and a faulty alarm system. Science Blogs shared in early 2011 a detailed breakdown of the events that contributed to the fatality, including that the plant had rejected using a stronger hosing material,less vulnerable to chemical degradation.

While Material Test Reports (MTRs) and Pressure Test Certifications (PTCs) are included with every order, as part of our commitment to quality, tragic events such as this one emphasize how important it is to use a chemical hose compatibility tool, perform monthly quality checks, and work with a trusted vendor that has prioritized your safety and productivity over their profit.


Right now, try this quick 5-point inspection of your chemical hoses:


1.     When is the last time your chemical hoses were checked for fraying?

2.     Are your chemical hoses showing signs of corrosion?

3.     How often does your plant replace your chemical hoses?

4.     Have you checked the chemical hose compatibility against the chemicals you are using with it?

5.     Does your chemical hose supplier test the chemical hoses and guarantee their quality?

Is Your Hose Fitting Supplier Ensuring Quality and Consistency?

Our Investment In Ensuring Quality Part 2 - Machined Components

FlexFit-Hose-Machined-Components-2If you are like most of the manufacturers we hear from, you work with multiple outside sources to supply your hose fittings and crimp ferrules. Time and again, during those first conversations, we hear that the biggest challenge is ensuring quality and consistency across vendors. The next biggest gripe we hear is how difficult it is to receive a quick response to any modifications needed for your unique situation. Why is this so difficult?

We don’t think it has to be.


Here’s why: CNC Swiss machines and a dedication to quality. That’s our secret sauce, out for all to see. Swiss machining is much more precise than more conventional machines. Originally used for machining small precision parts that made Swiss watches famous for their accuracy, these machines are now used in a variety of manufacturing environments, and have been gaining in acceptance in industries ranging from medical and aerospace to automotive and electronics, agrees Production Machining magazine. For FlexFit Hose, it means that we can provide a higher level of quality and consistency in our machined components. That’s the production part.


Next is quality. To ensure quality, every part is checked to be within tolerances that meet or exceed specification requirements. This is our hands-on approach to customer satisfaction. We check for any imperfections such as burrs, poor surface finishes, and inconsistencies of thread tolerances, any of which can prevent parts from fitting properly or can cause machinery to break down, resulting in a disruption in production schedules and potential loss of revenue.


Next, every component is cleaned properly to eliminate residual machining lubricants or other elements that could introduce contaminants that would be unacceptable for sterile or clean environments. The investment in inspection equipment, proper maintenance schedules and continual improvements of CNC machine programming are additional steps FlexFit Hose takes to ensure quality. This allows us to ensure peak utilization and result in high productivity, which means faster delivery time and less production downtime for our customers.

We also offer industrial hose assembly options, such as color coding, tagging and high/low temperature protection.


Finally, when vetting a supplier or fabricator of hose fittings, we recommend always asking these questions:

  • Do you use a CNC Swiss Machine to ensure consistency?

  • What steps do you take after production to make sure my hose fitting or crimp ferrule meets my quality standards?

  • Do you specialize in custom PTFE hose fittings?

  • How quickly and what is the process for requesting modifications to my hose fittings or crimp ferrules?

If these questions can be answered quickly and meet the guidelines we’ve shared above, then the vendor may make a good partner. If they can’t, then call FlexFit Hose and we will ensure you have the highest quality PTFE hose assembly, consistently, according to your specifications. Call us at 410-327-0758 or email 


Is Quality Assurance of Manufactured Products Diminishing?

An Investment in Ensuring Quality Part 1 - PTFE Hose Assemblies


FlexFit Hose C Flex Sanitary Tri Clamp FittingHave you noticed that it seems like products today are just not built to last? That quality in everything from electronics to household gadgets to industrial products used in your manufacturing plants fall apart, disintegrate, or seem to just fail -  way before reasonable value from the product’s use  is gained. In some cases, it is planned obsolescence -- that the products are designed to fail after a certain period of use. However, in many cases, the quality of products are diminished as companies attempt to optimize profit margins during an ongoing, volatile economic period. Unfortunately, it seems that many tip the scale to the bottom line, resulting in businesses and consumers on the receiving end of their poor quality products suffering.

One industry in particular is taking notice and demanding higher quality vendors -- as they should. According to LifeScience Leader, biopharmaceutical manufacturers have cited that 8 in 10 vendors have created quality problems for them. On top of that, they are often plagued by mismanaged change control and a history of overpromising, and underdelivering. The vetting process for new industrial hose manufacturers can be an arduous task.

While the rise in electronics are to blame for the failure of many appliances, which makes them vulnerable to power surges, water, and other elements, the article 10 Ways Products Are Designed to Fail,” says it pointedly: engineers no longer strive to create the best possible product. They aim for maximum profit through steady sales.


Standing up and maintaining a high level of quality while others are looking for the cheapest possible way to manufacture their products is an important part of FlexFit Hose’s philosophy as a PTFE hose manufacturer and hose fittings manufacturer. As we continue to provide PTFE hose assemblies as well as industrial hose assembly components for on-site fabrication, a key to delivering products of high quality requires a commitment to invest in each step of the process.

The primary steps in our process are:

  • Affirming that an assembly will meet or exceed specification requirements to perform properly
  • Ensuring proper attachment of the hose fitting to the ptfe hose so that a consistent fabrication process ensures hose assemblies function at peak performance during production.
  • Making sure fabrication is performed with the proper equipment - We make sure the right hose crimp tool is used and it is specified for the hose, as well as the specific components that were validated.
  • Continuing quality with hydrostatic pressure testing of every hose manufactured - this is done prior to shipment so that we decrease even the limited  risk of the hose failure in production
  • Providing material test reports and certifications - We back the quality of our PTFE hose assemblies 100% and provide test reports and certs with every order. Fabricators - does your current supplier provide these? They should.


In addition to our three-tiered quality service promise -- provide excellence in customer service, the highest quality in our PTFE hose assemblies, and thorough quality testing, we also believe in providing counsel for customers who fabricate FlexFit Hose PTFE hose assemblies on-site so that they may uphold the level of quality within their facility.
