Westinghouse Vibration Isolator for all Westinghouse units - Junior, Standard, Master, Giants, such as 3 Case, WD-5, WE-6, 6-Case, 10 Case, WE-10, WD-12, WD-20, WD-22, Coolerete (R-1), WC-42T, WC-44, BV-56, WC-96, DU-144, WC-160T, BV-240, V-4, V-10, and some V-83s that had Westinghouse Units.

This rubber isolator is bolted on the FRONT of the compressor and bolted on the chassis plate. One per unit keeps the compressor from bouncing on the chassis. On most old machines - pre 1950 we see them rotted or missing completely. This causes extra noise in your machine. This one is seen more often.
