PSA-58 Piston Seal
Style PSA-58 piston seals combine a heavy duty, fabric reinforced seal with two polyacetal “L” bearings. This construction allows the seal to withstand pressures up to 5,000 PSI. “L” bearings also react to pressure to prevent extrusion and support the piston. For 2-piece pistons.
