Value Collection 6LN1/2 Stainless Steel Lock Nut Npt

Product Description

The VALUE COLLECTION 6LN1/2 is a stainless steel lock nut fitting designed to secure and seal threaded pipe assemblies in plumbing, HVAC, and industrial piping systems. It features NPT (National Pipe Taper) threading for a reliable, pressure-resistant connection with standard tapered pipe threads. Measuring approximately 1.19 inches in width and 0.31 inches in length, this compact fitting is suited for tight installations where space is limited. Its stainless steel construction provides corrosion resistance in wet, chemical-exposed, or outdoor service environments. Licensed plumbers and pipefitters install this type of fitting as part of threaded pipe assemblies across residential and light commercial applications.

This lock nut is appropriate for use in residential and commercial plumbing systems, HVAC condensate and refrigerant line assemblies, and general industrial piping where NPT-threaded connections are standard. The NPT end connection makes it compatible with standard tapered pipe thread fittings widely used across trade applications. It ships as a single unit and is suitable for both new installations and maintenance or repair work on existing threaded piping systems.

Installation Notes

Installation is performed by licensed plumbers or pipefitters working on threaded pipe systems. Shut off water supply or system pressure and depressurize the line before servicing any threaded fitting. Use appropriate pipe wrenches and thread sealant or PTFE tape on NPT connections as required by local plumbing codes. Do not overtighten stainless steel fittings on dissimilar metal threads to avoid galling.
