Making sense of PTFE hydraulic hoses requires understanding the literal phrase &#;PTFE&#; and &#;hydraulic hose&#;, the former means materials from which the specific hydraulic hose is made, and the latter means the function and its application in which the hose can be used. PTFE hydraulic hoses are special in existence with the number SAE 100R14 hydraulic hoses and have unique properties for exclusive circumstances.
In this article, we will walk through PTFE hydraulic hoses in two parts, one focuses on the material &#;PTFE&#;, and the other focuses on their function &#;hydraulic hose&#;.
PTFE Hydraulic HosePTFE is the abbreviation of polytetrafluoroethylene, it is a kind of linear polymer like polyethylene(PE&#;, but the hydrogen atoms are replaced with fluorine atoms, from the PTFE Molecular Structure chart, we can see the main carbon chain is surrounded by fluorine atoms and the carbon-fluorine key is extremely stable, this structure entitles the PTFE unique characteristics.
This material is discovered in by the DuPont Co, Teflon is the trademark brand for this material, so when we compare the Teflon and PTFE material, in fact, they are the same concept.
PTFE has many exclusive properties than other polymers, all of these lies in its unique structure:
PTFE hydraulic hoses tend to be used in some particular scenarios, for instance, with the requirement of high chemical resistance, and high-temperature resistance.
PTFE hydraulic hoses have two plies unlike the conventional rubber counterparts, the inner tube is made of polytetrafluoroethylene which is directly in touch with hydraulic fluids, it can be compatible with almost any media and can sustain high temperatures up to 260°C.
The outer ply is braided reinforcement made of high-tensile stainless steel wire (SS 316), ensuring it can survive in a harsh environment.
Although PTFE has many advantages and can endure certain high working pressure, the working pressure top limit is only psi (15.1MPa) with an inner diameter of 1/4&#;, as the diameter increases, the W.P. decrease to 682 psi (4.7MPa) with an inner diameter of 1&#;.
Two types of the inner tube are available in our supply, one is the smooth inner wall, and the other is the corrugated inner tube, each of them has its advantages and disadvantages. Smooth PTFE hydraulic hoses have less friction and pressure loss than corrugated ones, but the latter has a more flexible preference than the former.
