General Machine Products Pressure Testing Ells - Manual

The B Pressure Ell may also be used on a splice case or "T" type cable
terminal. When used on a splice case or "T" type terminal approximately
3/8 inch of the pipe stem on the B Pressure Ell should be cut off. This is
necessary to allow the end of the pipe stem to clear the projections on the
splice case when it is being screwed into the flange on the case. A hack
saw may be used for cutting off the pipe stem, but care should be taken to
remove all metal deposits after sawing is completed. To install the B Pres-
sure Ell in a splice case, clean the pipe stem of the ell and coat it with
stearine. Coat the threads of the ell with an approved pipe joint compound
and screw the Ell into the pressure testing flange on the splice case. Make
certain the lead pipe is clean and dry. Push the end of the lead pipe onto
the pipe stem of the B Pressure Ell and solder in place, using C Stearine
Core Solder. Insert the F Valve Stem after soldering of the lead pipe and
pipe stem. (See illustration below.)

Where required, install an F Valve Stem into the female threaded hole of
the B Pressure EIl. Otherwise, close the Ell with a C Pressure Flange Plug.
In either event coat the threads with pipe joint compound before assembly.
