A/C Suction O-Ring - Yellow 10 Pack for Sanden WG Head - IHC 3543728C1 Red Dot 75R5535 830.52202Y-10

Half of A/C reseal work happens at the compressor, and the suction fitting is the other half of the pair. This A/C Suction O-Ring is the yellow suction-port seal for IHC applications and Sanden compressors with the WG head, supplied in a 10 pack. A weeping suction connection bleeds refrigerant out slowly and lets moisture find its way in, so the symptom is never a dramatic failure. It is a system that cools a little worse every week until someone finally puts gauges on it. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Sealed Both Sides: The WG Head Suction O-Ring Advantage

The suction port on a Sanden WG head takes its own dedicated seal. It is not the same part as the discharge O-ring and the two are not interchangeable, which is exactly why both belong in the drawer together. This one is yellow and it is the suction seal. Checking the port before the fitting goes back together takes a second and saves an evacuate-and-recharge cycle.

Sold as a 10 pack, because an O-ring is a consumable that belongs in stock rather than being ordered one at a time. Fitting a new seal every time a connection is opened is what prevents leaks and contamination at every reseal, and at this size there is no version of the job where reusing the old one is worth it. This Automann seal is a direct replacement for highly searched industry numbers including IHC 3543728C1, MEI 0137, Red Dot 75R5535 and Truck Air 16-4249.
