Figure 12 - Tee Purge and Diaphragm Valve with 1/4"
FPT Port shown with one cylinder per side.
System 621 X61X-CGA (one pigtail per side with diaphragm valves and tee-purge assembly) – see Figure 12 for
locations of components:
1. Tape the male NPT connections on the pigtail assembly, diaphragm valve assembly, and tee-purge assembly
using the procedure outlined on page 8.
2. After taping the male NPT connections, thread the 1⁄2 NPT of the diaphragm valve assembly into the
bulkhead connector of the autoswitch as shown in Figure 12. Wrench-tighten.
3. Thread the 1⁄4 NPT connection of the tee-purge assembly into the diaphragm valve assembly as shown
in Figure 12. Wrench-tighten. Note: while tightening the tee-purge assembly into the diaphragm valve
assembly, a second wrench must be in place holding the diaphragm valve. Failure to do so may cause the
diaphragm valve assembly to loosen.
4. Thread the 1⁄4 NPT connection of the pigtail assembly into the tee-purge assembly as shown in Figure 12.
Wrench-tighten. Note: while tightening the pigtail assembly into the tee-purge assembly, a second wrench
must be in place holding the hex of the tee-purge. Failure to do so may cause the tee-purge assembly to
loosen.
Connecting to a cylinder:
1. Before removing the cylinder cap, move the cylinder of gas to the work site:
a. Secure cylinder to the floor, wall, or bench with appropriate chain, strap, or stand to prevent
toppling.
b. Remove the cylinder cap.
c. Be sure the cylinder valve is tightly closed (clockwise)
d. Remove the cylinder valve plug, if any.
e. Inspect the cylinder valve and threads for damage or contamination.
