The VALUE COLLECTION 51016 is a snap-style pressure test plug used to temporarily seal ports, openings, and fittings during pressure testing of plumbing, HVAC, and piping systems. The plug features a 1-5/8 inch outer diameter and measures 1-3/16 inches in length. Its snap-tite design allows for quick, tool-free insertion and removal, making it well suited for leak-down tests, hydrostatic pressure checks, and pneumatic system verification. Plumbers, pipefitters, and HVAC technicians rely on plugs like this to isolate sections of a system without the need for threaded connections or adhesives.
This pressure test plug is appropriate for use in residential and light commercial applications wherever a port or opening needs to be temporarily blocked during system commissioning or diagnostic testing. The compact size and straightforward snap-in engagement make it practical for work in tight spaces. Its 1-5/8 inch OD fits standard ports and tube ends of corresponding diameter.
Designed as an OEM-style replacement and general-use pressure test plug for piping and HVAC system ports with a 1-5/8 inch opening diameter.
Installation is performed by plumbers, pipefitters, or HVAC technicians during pressure testing procedures. Always depressurize and isolate the system before inserting or removing the plug. Confirm the port diameter matches the 1-5/8 inch OD of the plug before applying any test pressure. Follow all applicable local codes and system manufacturer guidelines when conducting pressure tests.
