nipple with twisting motion until seated against nipple chamfer. Push socket forward, and hand start
threading of socket to nipple.
D) Wrench tighten nipple hex until clearance with socket hex is 1/32 in or less. Tighten further to align
corners of nipple and socket hexes. Clean and inspect all assemblies.
After the conduit is prepared, the liner may be cut to length and installed as shown in Figure 2.4 and explained
