Nitrile (NBR)

Service recommended : Standard
Temperature recommended : –4 Deg C to +140 Deg C.
Markings on Lip seals : ABCO, SIZE, CWP

 
Nitrile is specially formulated to give low temperature flexibility coupled with resistance to most oil well fluids and has excellent resistance to mineral oils. Good resistance to CO2 and explosive decompression.


Fluorocarbon (FPM)

Service recommended : H2S ( Sour gas )
Temperature recommended : –25 Deg C to +200 Deg C.
Markings on Lip seals : ABCO, SIZE, CWP


Formulation from a Fluroelastomer gives good service in sour gas conditions. The material has better high temperature properties than Nitrile and resists acids better.
