Hydraulic O-Rings
Hydraulic O-rings seal fittings, cylinders, valves and pumps in hydraulic systems. The right compound and size stops leaks and holds up under high pressure and temperature.
O-Ring Options
- Nitrile (Buna-N) – standard petroleum oil service
- Viton (FKM) – high temperatures and chemicals
- Polyurethane – high pressure and abrasion resistance
- Backup rings – prevent extrusion
- O-ring kits – assorted sizes for maintenance
Choosing O-Rings
Match size (AS568 or metric), durometer and compound to the fluid, temperature and pressure. Use backup rings above about 1,500 psi.
