Superb Sealing Rings

Overlay Step Cut:

Seals With Minimal Leakage

Step cut ring with a cast iron or bronze tongue that extends past the joint on the outer side, and the step fits within the inside to seal the joint.

Complete Seal

Seals both side and back of joint for complete seal on all sides.

Multiple Piece Compression Rings

Multi-piece rings are specially designed for high-pressure service. In most applications, they keep leakage to a minimum. In both the two and three-piece designs, the inner butt cut ring seals the outer ring(s). The outer rings can be made an angle or step cut. With the joints staggered, the inner ring provides the sealing needed for the outer ring joints. Recommended for high-pressure sealing and when minimal leakage is a must.

Segmented Rings

Segmental rings consist of pieces joined by step joints. The segmental rings permit much heavier walls (cross-sectioned) then is possible with one-piece rings which must be sprung over a piston. An inner compression ring provides tension for the segmented ring.

Bronze Filled Piston Ring

Cast iron ring with a single or double bronze insert on the face of the ring. Helps seat the ring and tends to prevent blow-by in either new or worn cylinders. The bi-metallic ring also reduces wear on both the ring and the cylinders.
