Dealing with Pipe Variances

Internal-ﬁt PVC ﬁttings, accessories and couplers attach to the inside diameter of Schedule 40

PVC pipe. ASTM standards allow for a larger variance in the inside diameter of PVC pipe

from manufacturers and often times the inner diameter may be too large, or even too small to

accept the internal-ﬁt ﬁtting or accessory. To remedy this, do one of the following steps to

resolve the issue:

THE PIPE INNER DIAMETER IS TOO SMALL:

THE PIPE INNER DIAMETER IS TOO LARGE:

Securing

For permanent and strong connections, it is!recommended to use!PVC cement/solvent to

attach the PVC pipe and the internal coupling.

You can also temporarily connect the coupler by driving a self-tapping screw where the pipe

and cap meet, or apply electrical tape over the end of the internal ﬁt component for a

temporary, yet strong connection.

Run a kitchen knife or blunt object around the edge of the inner

diameter of the pipe to taper it. This will allow easier insertion

of the internal-ﬁt item into the pipe.

Use PVC cement to connect the internal-ﬁt ﬁtting into the pipe

for a permanent connection.

As a temporary connection, wrap electrical tape around the end

of the internal ﬁt ﬁtting/accessory, then insert it into the PVC

pipe.
