Page 10 / Catalog OEM-1, Couplings 5500 Series Self-Sealing Brass Coupling Parker’s 5500 self-sealing brass couplings allow for pre-charging of AC and heat pump systems. The couplings provide for easy maintenance and installation on refrigeration and air conditioning systems. Applications can also include marine refrigeration and air conditioning systems, split refrigeration, and portable cooling solutions.
Catalog OEM-1, Couplings / Page 11 How It Operates Disconnected 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.

Use a double tip torch to promote even heating and reduce braze time. Note: Liquid flux or excessive flux can run inside the coupling and cause corrosion. ■■5780 and 5781 female halves: Water level should be halfway up the nut and the nut hex fully immersed.
Catalog OEM-1, Couplings / Page 23 Line-Set Field Installation Instructions Step 1 Apply refrigerant oil to the entire surface of diaphragm, o-ring, and threaded area of male coupling assembly. The amount of lubricant used must cover all designated surfaces sufficiently. Ideal application is a small applicator brush saturated with lubricant and applied liberally. An alternate lubricant for this application is a refrigerant compatible silicone grease product like Dow Corning DC200/60,000 cst.

The O-ring is only used for sealing between the time the diaphragm is pierced and the final metal-to-metal seal is made. Charging Port Cap The final leak-proof seal is a metal-to-metal connection made between the male and female coupling bodies. Mounting Flange Step 1 Upon disconnection, remove O-ring.
