The VALUE COLLECTION 51008 is a snap-style pressure test plug designed for use in pressurized piping and HVAC systems where temporary port sealing is required during leak testing or system commissioning. With a 13/16 inch outer diameter and a body length of 11/16 inch, this plug snaps securely into test ports to hold pressure without the need for threaded engagement. It is a compact, single-use-style fitting suited for plumbing, HVAC, and mechanical contractors who need a fast, reliable seal during pressure diagnostics.
This plug is commonly used in residential and light commercial applications where pressure test ports are built into piping assemblies, manifolds, or fittings. The snap-tite design allows for quick installation and removal, making it practical during rough-in inspections, system startup, or any workflow that requires repeated access to test ports. Plumbing and HVAC technicians typically keep these on hand as expendable service components.
Designed as an OEM-style replacement or service component for standard 13/16 inch pressure test ports found in residential and commercial piping assemblies.
Installation is performed by plumbing or HVAC technicians during pressure testing procedures. Depressurize and isolate the system before inserting or removing any test plug. Verify the plug is fully seated and locked before applying system pressure. Follow applicable IPC or IFGC code requirements for test pressure limits and duration.
