Polyurethane O-ring kit, aftermarket

For the construction machines: polyurethane O-ring kit, an aftermarket part. Polyurethane O-rings resist abrasion and high pressure.

When picking a ring from the set, compare the inside diameter and cross-section with the old ring or the groove size, since even a millimetre's difference causes a leak or a crushed ring. The rings in the set are general-purpose; for high-pressure hydraulic joints, high temperatures or special fluids, a ring made to a specific part number is preferred.
