Product Selection and Installation

Choose service port caps according to the connection size, thread type, pressure requirements, and equipment specifications. Some systems require caps with compatible sealing gaskets or O-rings to help maintain a proper seal.

Inspect the cap and sealing components for wear or damage, and tighten according to the manufacturer’s instructions. Service port caps should not be considered a substitute for proper valve sealing or leak testing. Refrigerant system servicing should be performed by trained personnel using appropriate tools and safety procedures.
