MTM Hydro Replacement O-Ring | For 3/8" Quick Connect Couplers | Single O-Ring

Priced per O-Ring - we also offer these in 10 packs and a Mixed pack with 1/4" o-rings

MTM Hydro's O-Rings will fit in any 3/8"coupler in the U.S. Market. We, alone, sell well over 100,000 O-rings per year as this item is commonly (and accidentally) blown out at the worst of times. From amateurs to contract cleaners, everybody blows out O-rings, the difference is that the Pro's always have a few spares in the truck.

Don't get caught without a few extra O-Rings on the job as these little items make a big difference in maintaining PSI, GPM, and safety.
