Pipe & Fittings Specifications
All pipe, fittings, primer and solvent cement must conform
with American National Standard Institute and the Ameri-
can Society for Testing and Materials (ANSI/ASTM) stan-
dards.The solvent shall be free flowing and contain no
lumps, undissolved particles or any foreign matter that ad
versely affects the joint strength or chemical resistance of
the cement.

Solvent cements for plastic pipe are flammable liquids
and should be kept away from all sources of ignition.
Do not use excessive amounts of solvent cement when
making joints. Good ventilation should be maintained to
reduce fire hazard and to minimize breathing of solvent
vapors. Avoid contact of cement with skin and eyes.
The cement shall show no gelation, stratification, or sep-
aration that cannot be removed by stirring. Refer to the
table 2 below for approved piping and fitting materials.

of PVC. Use PVC primer and solvent cement when
F438 using PVC vent pipe. When using ABS vent pipe, use
transitional solvent cement to make connections to the
D2241
PVC fittings in the unit.

ment meeting ASTM specifications, refer to Table 2. As an
alternate, use all purpose cement, to bond ABS, PVC, or
D1527
CPVC pipe when using fittings and pipe made of the same
D2468
materials. Use transition solvent cement when bonding
ABS to either PVC or CPVC.
D2661
Low temperature solvent cement is recommended during
cooler weather. Metal or plastic strapping may be used for
D2665
vent pipe hangers. Uniformly apply a liberal coat of PVC
