What matters

A practical guide to choosing the right part

Repair the assembly you actually have

Wear kits are grouped here by the component they service: minimum-pressure valves (MPVs), thermal valves, inlet assemblies, inlet solenoids, oil-stop valves, and condensate drains. Kits may contain seals, springs, pistons, or other small components, but contents vary by model and revision.

Match the full assembly number

A similar valve body does not guarantee that a kit fits. Check the assembly part number, compressor model, serial range, and kit contents before ordering. Some groups are still being built out; if the exact kit is not listed, send our parts team the numbers or photos you have.
