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. 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 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 Stainless Steel Couplers have EDPM O-Rings, although we do not sell replacements; instead, replace with FKM.
Also known as: O-RING Buna 10*2 Twist Coupler (Pack 25).
