GM Compressor hose adapter. This 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 O-ring connection at the hoses.
The male fittings point straight out the back of the Compressor.

Adapter center to center measurement is ~1-7/8″. This adapter comes with O-rings only. This will not work with Sealing Washers.
Make sure you measure the mounting holes on your Compressor Center to Center to ensure this adapter will work for your Compressor!

This adapter will not work with an R4 Compressor. If you need an adapter that works with the R4, use part# GM1602
