Approvals
Watts Quick-Connect fittings are designed for low pressure fluids. For
other applications please refer to our 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.
Watts Quick-Connect 35 Series products are designed and manufactured
to be trouble free for many years of service life. 35 Series products are
designed and manufactured in polysulfone, a high performance thermal
plastic material. All 35 Series products are approved and certified to NSF-
61, NSF-14, CSA B137.5, ASTM F877, and to the Uniform Plumbing Code
(U.P. Code) and ASSE 1061-2006. 35 Series 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, CPVC or polybutylene piping and snap a Watts Quick-Connect fit-
ting in place for a zero leak connection.
Caution: 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.
