One-Piece Compression Piston Ring

One-Piece Compression Piston Ring

The Safety Seal One-Piece Piston Ring is normally made with a radial thickness suitable for springing over the head of a solid piston, but when it is to be used on pistons of the built-up type with a removable head or follower, the type piston and the groove depth should be specified so that a ring with greater thickness may be furnished.

This type of ring is regularly manufactured with built-in tension so that an inner ring is not necessary. However, a spring-tensioned ring can be supplied grooved for stainless steel or monel wire expander; or fitted with flat, hoop-type stainless steel expander.

The One-Piece Piston Ring is furnished with butt, angle or step-cut joint. Step cut will be furnished unless otherwise specified. Also available in 2 piece angle, butt or step cut.
