Is the Steel 90° Tube End with R134 Valve, UNF GW, Type 52719 compatible with both R134a high-pressure (16 mm) and low-pressure (13 mm) systems?

Yes. The Steel 90° Tube End with R134 Valve, UNF GW, Type 52719 is offered in versions compatible with both R134a high-pressure (16 mm) and low-pressure (13 mm) systems. It is specifically available with either a 16 mm high-pressure R134 valve or a 13 mm low-pressure R134 valve, and its precise internal UNF thread ensures a secure, leak-resistant connection for both configurations. The steel construction and compact 90° design make it suitable for reliable installation and durable operation in the respective high- and low-pressure lines.

Can the Steel 90° Tube End with R134 Valve, UNF GW, Type 52719 be used interchangeably on both high-pressure (16 mm) and low-pressure (13 mm) ports without adapters?

No. The Steel 90° Tube End with R134 Valve, UNF GW, Type 52719 is offered in two distinct valve/port sizes — a high-pressure version with a 16 mm valve and a low-pressure version with a 13 mm valve. Those sizes correspond to different sealing faces and valve dimensions, so they are not interchangeable on the opposite port without an adapter or modification. Each version is engineered for a specific hose/port size to ensure a proper UNF-threaded, leak-free connection and reliable system pressure handling. Using the wrong size risks poor sealing, leaks, and possible damage to the valve or system.
