FEATURE
Sizes range from 1/16” to 2”.
Fittings are properly packaged with the exposed threads protected
to ensure they are not damaged during delivery.
All pipe threads meet the requirements of ASME/ANSI B1.20.1
(1983) for tapered pipe threads (NPT).
Working pressures are calculated in accordance with Power Piping
Code ANSI B 31.1, Rener Piping Code ASME/ANSI B 31.3 and
section VIII of ASME Boiler & Pressure Vessel Code.

INSTALLATION INSTRUCTIONS
To ensure a leak-tight seal, HAM-LET recommends the use of a
pipe thread sealant on all NPT threads. The most effective sealing
method is PTFE tape. Tape should be used only on male tapered
pipe threads.
Do not use tape on ared, coned or tube tting ends!
Clean both male and female tapered threads. Wrap tape in the
direction of the male tapered thread spiral.
ORDERING INFORMATION

120H 1/2
Material Description
SS - Stainless Steel 316
B - Brass
All orders should include
ordering information and
material description.
Note: Two wraps are suggested for stainless steel tapered pipe
threads. Make sure tape does not overhang the rst thread, as the
tape might shred and enter the uid system.
Cut off excess tape. The connection is now ready for proper makeup.
