- Easy installation
Hydrogenated Nitrile Rubber (HNBR), also known as Highly Saturated Nitrile (HSN), is a compound with superior heat, ozone, chemical resistance, tensile strength and abrasion resistance over natural rubber. HNBR provides excellent service life in most sealing applications such as oilfield, automotive and refrigerants.

Features
- Chemical resistance
- Tensile strength
- Abrasion resistance
- Excellent service life in most sealing applications such as oilfield, automotive and refrigerants
Split Teflon backup ring with a flat cross-section.
PTFE can withstand high temperatures and is compatible with nearly all fluids.
PTFE Material | 3/32 in Nominal Inner Diameter | 1/16 in Cross Section | Backup Ring
Features
- High strength and abrasion resistance
- Wide temperature range
- Chemical resistance
- Low friction
- Easy installation
- Deals very well with surface wear
Quad® Rings provide improved stability and lubricity over conventional o-rings, reducing the tendency to spiral in the groove. They interchange standard o-rings in a variety of static and dynamic sealing applications including rotary, reciprocating or oscillating motion.
Buna-N QUAD® Rubber Material | 3/32 in Nominal Inner Diameter | 1/16 in Cross Section | X-Ring
Features
- Reducing the tendency to spiral in the groove
- Interchange standard o-rings in a variety of static and dynamic sealing applications
- Pressure range varies according to diametral clearance
- Temperature range of -40 °F to -240 °F
Parback® backup ring with a curved cross-section.
Parbaks are contoured on one face to minimize distortion of the o-ring when under pressure. Parbaks should be installed with the contoured face against the o-ring, but reversal does no harm.
90A Durometer | Buna-N Rubber Material | 3/32 in Nominal Inner Diameter | 1/16 in Cross Section | Backup Ring
Features
- Excellent extrusion resistance
- Easily stretched for installation
- Lubrication is enhanced by rubber which absorbs system fluid and does not plate out on rubbing surfaces
