STEP 5
Attach Strainer Body to End Connector Socket and begin to
tighten Union Nut.
DO NOT USE THE REMAINING UNION NUT TO DRAW TOGETHER ANY
GAPS BETWEEN THE END CONNECTOR AND THE STRAINER BODY
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

-
Threaded
connections
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.
STEP 2
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-
Strainer socket.
STEP 3
Wrench Make Up
- Threaded pipe and strainer
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.
Strainer Basket must be pointed DOWN for proper operation.
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 STRAINER
BODY AND IS FLUSH AGAINST THE O-
RING.

FLANGED CONNECTIONS
STEP 1
Use of well lubricated
bolts & fl at washers are required. Use
an anti-seize lubricant such as IMS
Copper 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.

Once a fl ange is attached to the pipe or valve, the
method of joining two fl anges are as follows:
3" & 4" STRAINERS
Place rings as shown over the fl ange
hubs at each end of the strainer body.
Insert new bolts, washers and nuts into
new pipe system fl anges, through gasket
and into the split ring fl ange in alignment.
