5 Key Factors to Consider When Buying PTFE Hoses

PTFE is a very versatile polymer. It's a polymer that has very high chemical resistance and high service temperature of 260 deg Celsius.
PTFE is extruded using an extrusion technique called paste extrusion. PTFE can be paste extruded to form pipes and tubes. Tubes extruded from PTFE are milky white in color and semi flexible. The PTFE tubes in natural virgin form are electrically non conductive however it is possible to add a conductive agent to PTFE and extrude PTFE conductive tubes also called anti static tubes. The PTFE tubes can then be braided to manufacture PTFE Hose also known as PTFE Braided Hose.

There are 5 key factors to consider when buying PTFE Hose and they are as follows :

1. The PTFE tube quality.

PTFE tube is the most important component of PTFE hose and the challenging component to manufacture. Many properties of  PTFE tubes have to be considered like density, tensile strength & elongation. The density of a good quality PTFE tube should be in the range of 2.15 to 2.18. The elongation of a good quality PTFE tube.

should be more than 250% and the tensile strength should be greater than 250 Kg/cm2, the high the tensile strength the better. PTFE tubes when extruded may develop pin holes during the extrusion process. Manufacturers of good quality PTFE tubes will have a very tight control on the process variables to ensure defect free PTFE tubes. One way to assure that PTFE tubes are pinhole free is to pressure test to ensure there are no pin holes.

The other important factor is the uniformity of the PTFE tube wall thickness. PTFE tube concentricity([Min Wall thk / Max Wall Thk]*100) should be more than 80%. This ensures that the burst pressure or proof pressure is uniform across the length of the PTFE Hose coil length.

2. Burst Pressure

PTFE hose conform to standards like SAE 100 R14 and others. PTFE Hoses are named based on their bore. so a 1/4' PTFE hose will have a 1/4' bore. The OD of the hose will vary from manufacturer to manufacturer. Each PTFE hose size has a minimum burst pressure account to various standards. The burst pressure of a 1/4' PTFE hose is around 700-720. When buying PTFE hoses ensure that the burst pressure and hence the working pressure confirms to a standard applicable to your industry.

3. Bend Radius

PTFE hoses are used in equipment with tight spaces. It's needs to be bent to connect two ports. The minimum bend radius, in this case, becomes an important factor. The lower the bend radius the better it is. Choose a PTFE hose with a bend radius that confirms to industry standard or that suits your requirement.

4. Braid Material

The most ubiquitous braid material is SS304, and the quality of SS304 wire has a big impact on PTFE hose quality. The SS304 braid cover provides reinforcement to the PTFE tube which ensures the PTFE hose service pressure is high. The diameter of the SS304 braid wire has to be uniform to ensure the service pressure of the resultant PTFE hose assembly is within a narrow range.

5. PTFE Hose Testing

Customers procure PTFE Hose based on a technical data sheet. The question is what % of PTFE hose procured confirms to the specification. PTFE Hoses undergo rigorous testing like proof pressure test, burst pressure test, elongation test and so on.

Are you looking for the right alternative to rubber hoses? PTFE or Polytetrafluoroethylene Hose is an ideal choice with versatile properties. The common name of PTFE is Teflon which is an inert material. It is a completely stainless-steel hose that has a longer lifespan than a rubber hose due to its enhanced durability. Moreover, it is a popular choice in various industries due to its excellent chemical compatibility, shock resistance, flexibility, and non-stick properties of facilitating flow.

However, you can bring all the benefits of PTFE hose to your operational facility by investing in a reliable and trustworthy hose manufacturer. Choose manufacturers with years of experience and expertise in hose manufacturing.

A] Key Factors to Consider When Choosing a PTFE Hose Manufacturer

When doing research on PTFE hose manufacturers, you need to be aware of certain factors starting from hose quality to price. Here is the list of factors to check out in order to choose the Best PTFE Hose Manufacturers to meet your regular industrial applications.

1. Quality And Durability

The foremost factor is to check out for superior quality and durable properties. It is recommended to go for seasoned manufacturers with great experience in different hose types. Reputed manufacturers have a team with advanced knowledge, proficiency, and skills to meet the demanding hose needs of clients from different industrial sectors. Whether you want standard PTFE hoses or custom-designed hoses, make sure the manufacturer guarantees you the best quality. Go for high-quality PTFE hose manufacturers who understand your unique requirements and tailor-fit the product accordingly.

2. Manufacturing Standards And Certifications

A very important consideration is going through the certifications of the manufacturers. Invest in PTFE hoses that meet stringent standards in order to ensure higher reliability, performance, and safety; for example, a Smooth Bore PTFE Flexible Hose is recommended for fluid transfer in various industrial uses. Make sure the manufacturer follows the standard guidelines and protocols for meticulous material and conducts rigorous testing. Keep in mind to choose only certified hoses that have undergone advanced manufacturing techniques and adhere to best industrial practices. The manufacturer you opt for must have a broad portfolio of certifications that guarantees that their hoses meet the necessary requirements for your applications.

3. Customisation Options

When choosing the right PTFE hose for your application go for manufacturers who prioritise customisation. Ensure that they have the expertise to develop custom designs and formulations to meet extreme conditions. They must have the ability to optimise hose designs for enhanced performance. Choose manufacturers who are innovative and tailor-fit the hoses to provide best-in-class hose solutions. Customising the hose design includes the ability to customise material choice, dimensions, and features to offer a suitable hose solution for any scenario.

4. Customer Reviews And Reputation

Do not forget about reviewing the reputation of the hose manufacturer. You can decide how to choose PTFE hose manufacturers by conducting a comparison of their reviews and ratings. You can visit review platforms or sites where the clients state their experiences, views, and opinions. You will get valuable information about the top hose manufacturers in your city from the reviews. Moreover, research about what reputation the manufacturer is holding among its previous clients. Are they maintaining long-term partnerships with their clients? If yes, then it clearly shows that the manufacturer is trustworthy and you can count on them.

5. Price Compared To Quality

After all the above research, you need to compare the price of the hoses. Make sure the price tag the manufacturer gives to the PTFE hoses is worth it. Never go for a cheaper hose to cut down your overhead costs, as you may end up with a low quality. Investing in a little more high-quality and advanced designed hose is always a good idea. So, prefer not to compromise with the quality, going for a cheap quality and better make a comparison.
