Common Myths About PTFE Braided Tubing (Teflon Hose) To Avoid

Hoses built with a Teflon (PTFE) core work exceptionally well in challenging circumstances.

For this reason, they can be found in items such as the space shuttle, aircraft landing gear, self-contained breathing apparatus, and braking systems.

The Teflon hose is most commonly used in aerospace and harsh industrial settings, but it is rarely required for normal hydraulic or pneumatic systems.

This post will cover in full how to select the appropriate hose and how to do so while avoiding several typical blunders.

Three Teflon Hose Myths To Avoid

Beware of these typical misconceptions or "myths" concerning Teflon hoses to prevent application problems in your designs.

Teflon hoses are a high-cost item.

When the whole cost of ownership is taken into account, a high-grade hose that is made of premium Teflon PTFE paste is frequently a more cost-effective option than conventional ones.

When evaluating the cost and performance of hoses, there are several things to take into account. Under almost any operating circumstance, a Teflon-made hose will outlast a rubber or thermoplastic hose that is just regular.

Although it is virtually always present and typically significant, the advantage is greatest under the most challenging circumstances. Depending on the application, this element may or may not be sufficient to justify the greater initial cost of a hose made of Teflon, but the majority of the time, the answer is "no."

Teflon-made hoses can help lower warranty costs for goods like industrial or commercial coffee makers that often get little to no upkeep from customers. When utilized to drain hot materials like fryer fat in fast food restaurants, they also provide a safety component.

Other benefits of Teflon-made hoses can significantly reduce costs in more specific application areas. Here, the solution is straightforward.

Hoses should be assessed based on their overall lifecycle cost, not just the original purchase price, just like everything else. When seen in this light, Teflon-made hoses frequently prove to be the most affordable choice.

Hoses made of Teflon frequently kink and break 

All hoses, especially those that are applied incorrectly, tend to kink and crush quickly. Teflon-manufactured hoses are equally as good as those produced of other materials when the suggested bend radii and loadings are followed.

It is straightforward to add internal or external spring guards to the hose at vulnerable spots in situations where kinking or crushing is a possibility.

Additionally, choosing a hose with larger walls and an intricate bore can reduce kinking and prevent crushing.

Teflon hoses come in all the same varieties

The term "Teflon" refers to a broad class of fluoropolymer-based materials, not all of which share the same characteristics. In the hose industry, Teflon is commonly utilized in two different forms: melt-extrudable (such as PFA, FEP, or ETFE) and paste-extrudable (PTFE).

Material that can be extruded as a paste has a higher melting point than material that can be extruded as a melt. There is also less resistance to flex fatigue in them. All of these inferior physical characteristics are represented in the melt-extrudable Teflon products.

Teflon 62 is the most effective PTFE resin utilized in hose fabrication. Teflon 62 cannot be continuously extruded because it is not a thermoplastic, which has historically restricted the length of the hose that can be produced.

The most recent paste extrusion machinery can now create longer lengths of PTFE hose.
