MTM ORING (Gun)

MTM Hydro's M22 replacement o-rings will fit in any 14mm version in the U.S. Market. We, alone, sell hundreds of thousands of 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 spare O-Rings in the truck.

As a Wholesaler, we receive these by the thousands and offer them in 25 and 100 packs only.

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.

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.
• FKM is a more expensive and durable compound meant for Hot Water and performs well with Chemical applications. Use the FKM Series of O-rings for replacement on Stainless Steel Fittings.
• EDPM is more expensive and durable compound that performs well with Hot water but excellently with Chemical Applications. All MTM Hydro Stainless Steel Couplers have EDPM O-Rings, although we do not sell replacements; instead, replace with FKM.
