STEP 4
Immediately following the application of solvent cement, and before it begins
to set, insert the valve end over the pipe end, push with a 1/4 twisting motion
to evenly distribute the solvent cement within the joint. A full bead of solvent
cement should form around the circumference of the joint. Hold joint together
for approximately 30 seconds to make sure that the pipe does not back off of
socket. Use a cloth to remove any excess cement from the exterior juncture.
Assemble other pipe into the Y-Pattern Valve socket.
Allow joint to cure according to solvent
cement manufacturer's instructions
THREADED CONNECTIONS
WARNING: SOME PIPE JOINT COMPOUNDS OR TEFLON PASTES MAY
CONTAIN SUBSTANCES THAT COULD CAUSE STRESS CRACKING
TO PLASTIC. TRANSITIONS TO METAL PIPE REQUIRE THOROUGH
CLEANING AND DEGREASING TO REMOVE ANY PIPE THREAD
CUTTING OIL.
Spears Manufacturing Company highly recommends the use of Spears
®
BLUE 75™ thread sealant, which has been tested for compatibility with
Spears products.

STEP 1
Apply Joint Sealant - Threaded connections
require application of a quality grade thread
sealant to seal and lubricate the joint
assembly. Sealants must only be applied to
male pipe threads.
Please follow the sealant Manufacturers'
Application/Installation instructions. Choice
of another appropriate thread sealant is at
the discretion of the installer.
Assemble Joint - 1 to 2 turns beyond
"FINGER TIGHT" are generally all that is
required to make a sound plastic threaded
connection.
Unnecessary OVER TIGHTENING will
cause damage to both pipe and Y-Pattern
valve threads.

STEP 3
Wrench Make Up - Threaded pipe and valve components must always
be installed using commercially available strap wrenches. Do not use
conventional pipe wrenches, which can cause damage to plastic piping
materials. Apply wrench make-up of no more than 1 to 2 turns beyond fi nger-
tight thread engagement. Care must be taken in fi nal positioning so as to
avoid the need to "Back-up" the wrench assembly.
Once a fl ange is attached to the pipe or valve, the method of joining two
fl anges are as follows:
STEP 1
Use of well lubricated bolts & fl at
washers are required. Use an
anti-seize lubricant such as IMS
Cooper Flake.
®
STEP 2
With a 1/8" gasket having a shore "A" durometer of approximately 60 in place,
align the bolt holes of the mating fl anges by rotating the ring into position.
Insert all bolts, washers, and nuts. Tighten the nuts by hand until they are
snug.
AT THIS TIME, BE SURE THAT THE FLANGE AND GASKET SURFACES
ARE FLUSH AND SQUARELY ALIGNED.
