Overview

If a breaker starts losing impact punch or runs hot, blow-by around the piston seal is often the culprit. Fitting directly in the piston groove, this ring rides the cylinder wall to contain high hydraulic spikes without dragging down stroke speed. Built tough enough to resist micro-dieseling and heat buildup from constant rapid firing, keeping the piston cycling cleanly.

Features

Fits piston ring grooves to stop bore bypass
Handles rapid cyclic pressure surges
Resists heat breakdown from continuous striking

Applications

Seated in the cylinder bore across hydraulic breaker piston assemblies
