Parker PT-00309 Compression Tube Plug 1-11 in Thread

Product Description

The PARKER PT-00309 is a compression tube plug designed to seal the open end of a compression fitting or tubing line. Constructed from steel, this plug terminates unused ports or capped-off branch lines in fluid and gas distribution systems. The 1-11 inch thread size makes it compatible with standard compression fitting configurations used across plumbing, HVAC, and light industrial piping applications. Plumbers and HVAC technicians typically install this plug during system modifications, pressure testing, or when capping off a line that is no longer in service. Each package contains 5 plugs.

This compression tube plug is suited for residential and light commercial applications where a steel, threaded compression plug is required to close an open tubing end. Common install scenarios include capping branch lines during system reconfigurations, isolating unused ports on manifolds, and maintaining system pressure integrity during phased installations or repairs. The steel construction provides durability in both wet and dry service environments.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians. Shut off system pressure and depressurize the line before installing or removing any compression fitting component. Hand-tighten the plug first, then use an appropriately sized wrench to seat the fitting without overtightening. Work should comply with applicable IPC and IFGC codes for the jurisdiction.
