Providing you with a wide assortment of ST, straight through,  style couplers for all of your pressure washing needs. We offer American Made Couplers and Plugs, Safety-Loc Couplers and Plugs, Twist Fast Quick Connectors, and Easy Grip Insulated design quick couplers. For extreme conditions we reccommend the stainless steel couplers and plugs. Due to their chemical resistance and hardness they will last much longer than standard couplers and plugs. Stainless steel plugs will also not "mushroom out" as easy as a standard plug making them easy to separate for a long time. Looking for O' Rings that last? Try the Viton O'Rings, they are designed for higher chemical resistance and can withstand heat better than standard O' Rings.
