PERMASEAL
TWIN SEAL
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.
