Watts AquaLock™ Mini fittings are designed and manufactured to
be trouble free for many years of service life. Mini fitting products are
designed and manufactured in polypropylene, a rugged thermoplastic
polymer. All Mini fitting products are approved and certified to NSF-61-G.
Mini fitting products are available in standard imperial inch sizes. The
Watts AquaLock™ design allows for quick and easy connections without
installation tools. Simply cut the plastic or copper piping and snap a Watts
AquaLock™ fitting in place for a zero leak connection.
Watts AquaLock™ Mini 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 thor-
oughly tested prior to use. Do not use with explosive gases, petroleum
products, or other fuels.
CAUTION
!
The polypropylene material used in the AquaLock™ fittings can be com-
promised 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.
NSF/ANSI 61-G: Watts AquaLock™ Mini fitting products are tested,
certified, and approved for contact with drinking water.
FDA: Watts AquaLock™ Mini fittings are produced from
FDA approved materials.
