Working on Caterpillar equipment? This o-ring kit is a handy assortment of common seals that match CAT part numbers 4C4784, 5P8433, and 270-1535. The o-rings are made from NBR90 (nitrile rubber), which is oil and fuel resistant, and they come in a organized box with each size labeled.
Includes quantities like 10 pieces of 1P-3700, 1P-3702, etc., and 5 pieces of others – check the listing for the full breakdown. Perfect for field repairs, maintenance kits, or just having spares on hand.
Always make sure these are the correct seals for your specific CAT model and application. But if they match your parts list, they’re a reliable, affordable alternative to buying individual seals from the dealer. Keep your machinery leak-free and running smoothly.
