Sealing washer master — 48-compartment kit
The complete A/C sealing set — 48 part numbers and 173 pieces of sealing washers and metal gaskets, organized one-per-compartment in a labeled case. It covers Chrysler, GM, Honda, Jeep, Dodge, Caterpillar, and more, including color-coded, slimline, Stat-O-Seal, and metal-with-O-ring gaskets — the right seal for nearly any flare or block fitting on the bench.
