California Air Tools Quiet Flow 4710sq Compressor

This listing is for 1 set of 2 Cup seals only.  These are the piston cups that wear out after about 1 year of running and require replacement. Size: The cup seals are approximately 68 OD x 48 ID x 0.8 mm / 2.7 x 1.9 x 0.03 inches. The ID is the main dimension you need. The OD curves up around the retainer and comrpesses against the sleeve. A worn-out cup seal will not have the same measurement of the OD because of it being worn out.
Replaces the original tan colored cup seal with the new and improved black one we manufacture to outlast and outperform the original ones.
Once replaced, your compressor will run like new at the original PSI specifications. Fits models - 1.0 HP AIR COMPRESSOR CAT-4710SQ CAT-4710SQGK18
