Assembly Instructions
Steps:
1. After tubing or hose has been connected to adapters
1 and
12 , install O-Rings
2 and
11 . on adapters. Be sure O-Rings are not twisted.
2. Oil O-Rings
2 liberally with system fluid to prevent them from scuffing and tearing when coupling body is threaded on adapter.
3. S2 Half—Lubricate poppet face with system fluid. Insert poppet valve assembly
3 into body
4 . Tighten body 4 on adapter 1 . After body and adapter make metal-to-metal contact, tighten by rotating body
4 1/8” with respect to adapter
1 or torque per table value.
S5 Half—Oil O-Ring 9 . liberally with system fluid. Insert valve and sleeve assembly 10 into body
8 . Tighten body
on adapter
12 . After body and adapter make met-al-to-metal contact, tighten by rotating body 8 1/8” with respect to adapter
12 or torque per table value.
4. Coupling Connection—Lubricate gasket seal
5 on 5400-S2 half with system fluid. Thread union nut
on 5400-S2 half. Tighten union nut to torque values shown in table. Be sure S2 and S5 bodies do not rotate during connection.
