Metal C-Ring Seal

Spring-Energized Metal C-Ring Seal

Spring Energized Metal C-Ring is an enhanced Metal C-Ring. With an spring inside the substrate, Spring Energized Metal O-Ring can bear much greater load for rough surfaces, and can also achieve much lower leakage rate.

Metal C-Ring Seal

Standard Metal C-Ring Seal

By default, Metal C-Rings for internal Pressure or external Pressure are system pressure energized, they require low bolting load and have good spring back.

Metal E-Ring Seal

Metal W-Ring Seal

Sonkit Metal W-rings are designed to have low load, high spring back performance for high pressure/temperature applications. In service, Metal W-rings are pressure energized by the system which increases the contact stress and further minimizes leakage.

Metal O-Ring Seal

Spring Energized Metal O-ring Seal

An advanced version of Metal O-Ring seal. Spring Energized Metal O-Ring seals can withstand significantly larger loads for rough surfaces and have a much lower leakage rate because of the spring inside the tube.

Metal O-Ring Seal

Balanced Metal O-Ring Seal (Self-Energized/Vented)

Advanced version of the Metal O-Ring. It may utilize system pressure to energize the sealing effect since the tube has vented holes. Balanced Metal O-Ring is a preferable choice if the pressure is high.

Metal O-Ring Seal

Gas-Filled Metal O-Ring Seal (Pressure-Filled)

The Gas-Filled Metal O-Ring Seal (also known as a Pressure-Filled seal) is a specialized high-performance sealing element. It's a sealing choice for high-pressure/high-temperature applications with little spring back.

Metal Comma Ring Seal

Metal P-Ring Seal (Comma-Ring)

Sonkit Metal Comma Rings are designed for slow dynamic applications. The tightness with a Comma Ring is more than with any other metal seal a function of the shaft condition.
