CLEANING
Using a clean, dry cotton rag, wipe away all loose dirt and
moisture from the I.D. and O.D. of the pipe/tube end and the
I.D. of the fitting. DO NOT ATTEMPT TO SOLVENT-WELD WET
SURFACES.
DANGER: Solvent cements and primers are extremely flam-
mable and harmful if swallowed. Vapors are harmful. May
cause eye irritation and repeated or prolonged skin contact
causes skin irritation.
Keep away from heat, sparks and open flame. Use only with
adequate ventilation. Avoid contact with eyes, skin, and cloth-
ing. Avoid prolonged breathing of vapor. Close container after
each use.
FIRST AID: In case of skin contact, flush with water; for eyes,
flush with water for at least 15 minutes and seek medical
attention. Wash contaminated clothing before reuse. If swal-
lowed, DO NOT INDUCE VOMITING, call a Physician immedi-
ately.
PRIMING
The function of purple primer is to penetrate and soften the
bonding surfaces of PVC and CPVC pipe/tube and fittings.
(Primer is not required with ABS.) It is a product that penetrates
rapidly. It is very effective on the hard-finished, high-gloss
products now being produced.
Apply primer to the pipe/tube with a paint brush approximately
1/2 of the pipe/tube diameter. A rag is not recommended as
repeated contact with skin may cause irritation or blistering.
Apply primer freely in
the socket, keeping
surface and applicator
wet and in motion 5
to 15 seconds. Redip
applicator as neces-
sary. Avoid puddling in
the socket.
Apply again to the fitting socket. The second application is
especially recommended for belled-end pipe and fittings fabri-
cated from pipe stock, for many of them have especially hard
inside-surfaces.

Pressure & DWV Piping Systems (continued)
For checking penetration, you should be able to scratch
or scrape a few thousandths of an inch of the primed
surfaces away. Repeated application to either or both
surfaces may be necessary. Weather conditions affect prim-
ing action. In cold weather more time is required for proper
penetration.
NOTE: The pipe/tube ends can be rested on notched boards to
keep them clean and for ease of solvent cement application.
NOTE: There are “one-step” cements available for PVC and
CPVC that eliminate the need to use a primer. NIBCO recom-
mends that if a “One-Step” solvent cement is used to assemble
our plastic fittings into a system that the solvent cement manu-
facturer’s instructions for assembly be followed and be limited
to applications where established temperatures are 40°F or
higher. Whenever feasible and available, NIBCO recommends
using a “One-Step” solvent cement specifically formulated
with Lubrizol FlowGuard Gold® CPVC resin with NIBCO CPVC-
CTS fittings.
NOTE: NIBCO recommends use of purple primer and solvent
cement for assembling SCH80 solvent weld joints, in both
PVC and CPVC, in industrial applications, where the media is
beyond hot and cold water delivery piping.
SOLVENT CEMENT APPLICATION
Using the proper applicator (see chart - page 81 for specific
recommendations) proceed as follows:
1.
Apply a full even
layer of cement on
the pipe O.D. for a
distance slightly
greater than the
depth of the sock-
et of the fitting.
2. Coat the fitting
socket with a medi-
um layer, avoiding
puddling. On belled-
end pipe or fabri-
cated fittings, do
not coat beyond
the socket depth
or allow cement to
run beyond the bell.
3. Put a second full even layer on the pipe/tube O.D.
