Parker PT-00307 Compression Tube Plug 1/2-14 Thread Steel

Product Description

The PARKER PT-00307 is a steel compression tube plug designed to seal open compression fittings and tubing ends in fluid and pneumatic systems. It threads directly into a compression fitting port using a 1/2-14 inch thread size, providing a reliable mechanical seal without the need for additional sealant in properly prepped connections. This plug is a standard service component used by plumbers, HVAC technicians, and industrial pipefitters when capping off unused ports, isolating sections of a system during service, or permanently decommissioning a branch line.

This compression plug is suited for residential and light commercial plumbing, refrigeration, and pneumatic tubing applications where a threaded cap is needed to block flow or pressure at an open port. It is commonly installed during system modifications, repairs, or staged commissioning where a branch line must remain sealed until future use. Each package contains 5 plugs, making it a practical stock item for service vehicles and shop inventory.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Always depressurize and isolate the system before removing or installing any fitting plug. Inspect the mating port threads for damage or debris before threading the plug in. Follow applicable codes such as the International Plumbing Code (IPC) or system manufacturer guidelines for pressure ratings and approved materials.
