MTM Hydro boasts a premium Stainless Steel line of fittings that ensures our customers a worry free cleaning experience with no concern for corrosion or unreliable performance. They are commonly found at all joints where high pressure fluid may need to be disconnected after use. Other areas such as lances, tips, and foam cannons are convenient places to install these QC's and with MTM Hydro's stringent Quality Control you will not have to worry about locking balls falling out, missing O-rings, or collars that do not fully engage.
