O-ring 334 — NBR (Nitrile) 90A
Size
Inner diameter (ID): 66.04 mm
Cross-section (CS): 5.33 mm
AS568A size: 334
Material
Nitrile (NBR), hardness 90A
Good resistance to oils, fuels, hydraulic fluids, and many petroleum solvents
Not for strong acids, ketones, or other aggressive chemicals
Moderate abrasion resistance; limited ozone and weathering resistance
Temperature
Typical: -30°C to +100°C (-22°F to +212°F)
Shorter exposures above this may be possible depending on conditions
Use
Static and low-movement seals in oil/fuel systems, hydraulics, gearboxes, compressors, pumps
Notes
For high temperatures, strong chemicals, or dynamic seals, consider FKM, EPDM, or silicone
Ensure correct gland size and surface finish to avoid extrusion or leaks
Use compatible grease to help installation and extend life
Ordering
Sold as singles, packs, or bulk
Custom packing and inspection for large orders
