Value Collection 13375D Square Plug 1-1/4 in Malleable Iron

Product Description

The VALUE COLLECTION 13375D is a square pipe plug used to seal threaded pipe openings in plumbing, gas distribution, and industrial piping systems. Machined from malleable iron with a black finish, this plug meets Class 150 standards and carries a liquid and gas pressure rating of 300 psi. The threaded end connection allows straightforward installation into standard female-threaded fittings. It is sized at 1-1/4 inches and is sold in a package of five, making it well-suited for multi-point service calls or inventory restocking by licensed plumbers, pipefitters, and HVAC technicians.

This square plug is appropriate for use in residential and light commercial piping applications where a durable, low-profile plug is required. Common install scenarios include capping unused branch outlets on gas or water distribution lines, sealing test ports after pressure checks, and closing off service tees during system modifications. The black finish indicates standard malleable iron construction consistent with Class 150 piping components used in low-pressure gas and liquid service.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off system pressure and depressurize the line completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads before installation. Torque to hand-tight plus wrench-snug, and verify no leaks under system pressure before returning the line to service.
