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 thermal
plastic 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 in
standard 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 fitting in 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 installations
be thoroughly tested prior to use. Do not use with explosive gases, petroleum products, or other fuels.

Material Specifications Series 35
The polysulfone material used in the Quick-Connect fittings can be compromised by exposure to volatile organic compounds (VOC’s) and caustic chemicals. Therefore, DO NOT expose this product to any such chemical or foreign substance, which would include exposure to the following products: Pipe Dopes (thread sealants), bug sprays, lubricants, cleaners, paints, bleaches, acids, solder fluxes, plastic piping primers and cements, oxidizing agents, alkaline solutions, thinners, fuels, oil based caulks, hydrocarbons, spray foam of foaming agents (insulation). Watts recommends that all fittings and parts be stored in their original
packaging until installation to protect the fitting internals from dirt and debris that may cause damage to the o-ring and the o-ring guide.
It is also recommended that all threaded connections be made with Teflon tape only. Failure to follow these instructions will void the warranty and possibly result in leaks and water damage.
