Catalog OEM-1, Couplings / Page 9 Step 1 After tubing or hose has been connected to adapters** (1) and (12), install adapter O-rings (2) and (11)* on adapters. Be sure O-rings are not twisted. Step 2 Generously lubricate adapter O-rings (2) and (11) with the system lubricant to prevent them from scuffing and tearing when coupling body is threaded on adapter. Step 3 Adapter to S2 male coupling half connection. A. Lubricate poppet face with system lubricant. Insert poppet valve assembly (3) into body (4). Tighten body (4) on adapter (1). B. After body and adapter make metal-to-metal contact,...

Catalog OEM-1, Couplings / Page 11 When disconnected, spring-loaded valve assemblies in the male and female coupling halves are sealed to prevent refrigerant loss and the inclusion of air or foreign materials. A spring in the male coupling half presses the bonded poppet against sealing surface “A” of the coupling body. Likewise, a spring in the female coupling half presses the sleeve against sealing surface “B” of the stem valve head. An O-ring on the female sleeve prevents leakage between the sleeve and coupling body. Partially Connected Female Coupling Half Female Coupling Half Male...
