EPDM vs. NBR: Nitrile butadiene rubber (NBR) stands alone as the most oil- and fuel-resistant elastomer. It is also known for maintaining its stability in low temperatures. A sheet of NBR rubber can survive in temperatures as low as -22 degree Fahrenheit. On the other hand, EPDM sheet rubber lies on the opposite side of the spectrum and can operate at higher temperatures. The …

Even within hose temperature limits, end fittings and hose size can affect performance at higher temperatures. Service Conditions: A rubber compound usually swells when exposed to a chemical. Within a given percent of swell, a hose tube may function satisfactorily if the hose is in a static condition, but may fail quickly if the hose is subject to flexing.

PTFE is more chemical resistant than your average automotive elastomer like neoprene and EPDM. That is a “better.” Rubber will degrade well before a fluoropolymer is another way to say that. PTFE hoses also flow better as they have less surface friction. That is another “better.” The reason the fittings are different is the hardness of the liner. Rubber takes very little to seal it

Moreover, EPDM shows excellent environmental and chemical resistant properties. EPDM is known as M-class rubber since it has saturated chains of polymethylene.. What is the …
PTFE is a fluoroplastic (fluorine-based thermoplastic). It can have a fairly high density among thermoplastics. In addition, it can have a moderately high ductility and a fairly low tensile strength. EPDM is softer and makes a better sealing material (conforms better to rough surface finishes). polymer is stiffer and slicker, which might hold
