Watts Quick-Connect Series 35 products are designed and manufactured to be trouble free for many years of service life. Series 35 products are designed and manufactured in polysulfone, a high performance thermalplastic material. All Series 35 products are approved and certified to NSF-61-G, NSF 14, CSA B137.5, ASTM F877, and to the Uniform Plumbing Code (U. P. Code) and ASSE 1061.Series 35 products are available instandard imperial inch sizes. The Watts Quick-Connect design allows for quick and easy connections without installation tools. Simply cut the plastic, copper or CPVC tubing and snap a Watts Quick-Connect fittingin place for a zero leak connection. Watts Quick-Connect Series 35 fittings are designed for potable water systems. For other applications please refer to WATTS Technical Service Department.Tubing should be supported at minimum of 36" to prevent excessive load to the connectors. Do not install tubing supports closer than 3 inches from the connector ends. We strongly recommend that new installationsbe thoroughly tested prior to use.
