EPM Can manufacture Cast Iron Piston Rings fast (typically in 3-5 weeks)
Developed specifically to provide the lowest possible leakage of any metallic piston ring seal. The basic design consists of two Butt Cut outer rings, a spring steel anti-extrusion ring, and an elastomeric inner seal. When Twin-Seal is used to pass ports, each outer ring must be wider than the diameter of the port.
Used in automatic transmissions and wherever blind assembly requires passing counter-bores and oil passage slots.
A standard piston ring design with proven reliability for noncritical sealing applications.
Most often used where high leakage rates are permitted because of unrestricted oil flow through the open joint.
2 RING SET
A Butt Cut inner ring and a Step Cut outer ring provide excellent high temperature -" high pressure sealing performance.
3 RING SET
Best possible sealing with an all metallic seal. Set consists of 1 Butt Cut inner ring and 2 Butt Cut outer rings.
