metal o-ring

Product description

    Metal O-Rings are designed to provide a high sealing level under adverse working conditions whether the medium is gas or liquid.Metal O-Rings are manufactured from stainless steel or high temperature alloy tubing or wire. Sealing capability can be improved by platings or coatings such as Teflon®, silver, nickel or other malleable metals.

• PLAIN Type RD940 The plain seal type RD940 (Not self energized or Pressure filled) is made of metal tubing (or wire) available in most metal alloys. This type is the most economical O-Ring. It is designed for low to moderate pressure and vacuum applications for working conditions from vacuum to 70 bar

• SELF-ENERGIZING Type RD941 The surface exposed to the highest pressure, usually the inner periphery, is vented by small holes or slots. RD941 is recommended for pressure above 70 bar to 4100 bar .This feature allows the system pressure to enter the O-Rings, creating maximum specific pressure and reducing the pressure differential across the seal. For media other than high viscosity, one hole is sufficient.

• PRESSURE FILLED Type RD942 Pressure Filled O-Rings are designed for a temperature range of 425 to 982°C. The rings are filled with an inert gas at 41bar. At elevated temperatures, gas pressure increases to offset the loss of strength in the tubing and specific pressure.
