MTM Hydro 1/4" Viton - COUPLER O-RING
MTM Hydro's O-Rings will fit in any 1/4"" or 3/8"" coupler. Commonly (and accidentally) blown out at the worst of times. From amatuers to the detailers, everybody blows out O-rings, the difference is that the Pro's always have a few spare O-Rings on hand
Dont 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.
Types of O-Rings:
Buna Nitril is a common and inexpensive compound used in the O-Rings of all MTM Hydro Brass Couplers. This compound will perform acceptably at high temperatures but will deteriorate quickly and should only be used in cold water applications.
