Parker KP72508 Full Port Ball Valve 1-1/4 in Npt Bronze

Product Description

The PARKER KP72508 is a full port manual ball valve designed for 1-1/4 inch NPT pipe connections. The full port design maintains maximum flow capacity by providing an unobstructed bore equal to the pipe diameter, minimizing pressure drop across the valve. The bronze body offers reliable corrosion resistance in wet plumbing and HVAC hydronic applications. A reinforced Teflon seat provides a positive, low-friction seal against the ball. Operation is handled via a lever handle, allowing quick quarter-turn open and close actuation. Plumbers and HVAC technicians install this valve as a manual isolation point in fluid piping systems.

This valve is suited for residential and light commercial plumbing, hydronic heating, and HVAC water distribution piping. It is commonly installed as a service isolation valve on equipment connections, branch lines, or zone circuits. The 1-1/4 inch NPT threaded end connections allow straightforward installation into standard pipe assemblies using conventional threaded fittings. The lever handle makes its open or closed status easy to verify at a glance, which is useful in mechanical rooms and equipment closets where multiple valves are present.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IPC requirements. Shut off system pressure and drain the affected line section before removing or installing any valve. Apply thread sealant or PTFE tape to the NPT threads per standard practice, and do not overtighten threaded connections on the bronze body. Verify the valve is in the closed position before restoring system pressure and check for leaks at the connections after startup.
