Made from 70A ethylene propylene (EPDM), these O-rings are designed specifically for SAE straight-thread O-ring Boss (ORB) fittings in high-pressure hydraulic systems. They provide excellent resistance to weathering, abrasion, hot water, steam, silicone fluids, and phosphate ester-based hydraulic fluids. They seal primarily static applications. Not compatible with petroleum-based fluids or diester lubricants, these O-rings perform extremely well in virtually all brake fluids.
