motion to the inside socket of the End Connector until the surface is softened and
semi-
fl
uid. This will occur in 5 to 15 seconds, depending on size and temperature.
Apply primer to the outside of pipe ends in the same manner extending application
area to slightly beyond the insertion depth of the End Connector Socket. Apply a
second coat to both pipe and socket.
Check the penetration and softening by scraping the
primed surfaces. A few thousandths of the semi-
fl
uid
surface should easily be removed.
REPEAT PRIMER APPLICATION IF NECESSARY.
THE MOST FREQUENT CAUSE OF JOINT FAILURE IS INADEQUATE PRIMER
PENETRATION AND SOFTENING OF BONDING SURFACES DURING THE WELDING
OPERATION. TAKE EXTRA CARE THAT NO SOLVENTS ARE ALLOWED TO COME
IN CONTACT WITH THE BALL OR OTHER INTERNAL VALVE COMPONENTS.
STEP 5
Solvent Cement
must be applied IMMEDIATELY
to the primed surfaces before the
primer dries, in an alternating 3-coat
application. Using a brush or applicator
no less than 1/2 the pipe diameter,
apply a liberal coat of solvent cement
to the primed pipe surfaces. Next,
apply a light to medium coat to the End
Connector Socket primed surface. If a
“NET FIT” was experienced during
the dry
fi
t check (See Step 3) then
apply an additional liberal coat again
to the pipe surface.
STEP 6
Immediately following the application of solvent cement, and before
it begins to set, insert the End Connector Socket 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 End Connector Socket does not back off
of pipe. Use a cloth to remove any excess cement from the exterior juncture of the pipe
and End Connector.
Repeat STEP 6 to attach opposite end connector to pipe.
Allow joint to cure according to solvent
cement manufacturer’s instructions.

UNION NUT
Hold 30 Seconds
STEP 7
Attach Valve Body to End Connector
Socket and begin to tighten Union
Nut.
DO NOT USE ANY TYPE OF THREAD
SEALANTS. “HAND TIGHTEN
ONLY.”
BE SURE THAT THE FACE OF THE END CONNECTOR SOCKET IS
SQUARELY ALIGNED (FLUSH) WITH THE VALVE BODY AND IS FLUSH
AGAINST THE O-RING.
DO NOT USE THE REMAINING UNION NUT TO DRAW TOGETHER ANY
GAPS BETWEEN THE END CONNECTOR AND THE VALVE BODY.
STEP 8
Pressure test the system only after all solvent cement joints have
fully cured. If any leaks are found at End Connectors during pressure check, use a strap
wrench to tighten Union Nut 1/4 turn to stop the leak.
DO NOT OVER TIGHTEN AS DAMAGE MAY OCCUR
.

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.
RECOMMENDED SEALANT:
Spears

Manufacturing Company highly recommends the use of Spears
®
BLUE 75™
thread sealant, which has been tested for compatibility with Spears
®
products. Please
follow the sealant Manufacturers’ Application/Installation instructions. Choice of another
appropriate thread sealant is at the discretion of the installer.
