New black fittings for the Speedfit advanced push-fit fitting system have been specifically designed for water filtration and softener installations; however, they are also suitable for plumbing repair and remodeling, marine and R.V. applications. They are available in ¾- and 1-in. CTS sizes in elbow, tee, union, male and stem elbow configurations. They are lead free, ultraviolet resistant and easy to install, without the need for any tools. Their patented Lock & Twist technology, featuring a collet with stainless steel gripping teeth and an EPDM O ring, ensures leak-free connections. The fittings are IAPMO approved, NSF certified and can be used with copper CPVC or PEX pipe.
