GM compressor hose adapter with sealing washer kit.  This universal adapter will allow you to use any GM a/c compressor with an aftermarket a/c system or aftermarket hose kit. The adapter is designed to use a # 8 13/32″ a/c fitting and a # 10 1/2″ a/c fitting. The thread sizes are 3/4″-16 and 7/8″-14, and both fittings use oring connection at the hoses.  The adapter will work with the old O-ring style GM compressor or a sealing washer compressor.
