Standard Threaded Connection Practices
Threaded end connections should be manufactured to ASTM specifications D2464-99. F437-99 and
ANSI B2.1.
5.1.
Wrap threads of pipe with Teflon tape of 3 to 3-1/2 mil thickness. The tape should be wrapped
in a clockwise direction starting at the first or second full thread. Overlap each wrap by, 1/2
the width of the tape. The wrap should be applied with sufficient tension to allow the threads
of a single wrapped area to show through without cutting the tape. The wrap should continue
for the full effective length of the thread. Pipe sizes 2” and greater will not benefit with more
than a second wrap, due to the greater thread depth.
5.2.
To provide a leak proof joint, the pipe should be threaded into the end connection “hand
tight”.
5.3.
Using a strap wrench only (never use a stillson type wrench), tighten the joint an additional
1/2 to 1-1/2 turns past hand tight. Tightening beyond this point may induce excessive stress
that could cause failure.
