The VALUE COLLECTION 6 BZ-B is a brass compression cap tube nut used to terminate or seal a compression fitting connection in plumbing, HVAC, and refrigeration tubing assemblies. The compression cap style is designed to close off an open compression fitting end, preventing flow or protecting unused ports. Constructed from brass, it offers corrosion resistance and reliable seating against standard compression ferrules. This type of fitting is typically installed by licensed plumbers, HVAC-R technicians, or experienced tradespersons working on copper or compatible tubing systems.
This compression cap is suited for light-duty plumbing and mechanical applications where a standard compression-style end termination is required. Common uses include capping unused branch lines, sealing test ports, or terminating tubing runs during service or system modification. It is a small but essential fitting used in both residential and light commercial work.
Designed as an OEM-style compression cap fitting for use with standard compression tube assemblies in plumbing and HVAC-R applications.
Installation is typically performed by a licensed plumber or HVAC-R technician. Always shut off the water supply or depressurize the refrigerant or fluid circuit before removing or installing any compression fitting. Hand-tighten the nut first, then use an appropriately sized open-end or adjustable wrench to seat the ferrule without over-torquing the brass body. Follow applicable IPC or local plumbing code requirements for fitting use in pressurized systems.
