Value Collection 6LN3/4 Stainless Steel Lock Nut Npt

Product Description

The VALUE COLLECTION 6LN3/4 is a stainless steel lock nut designed for use with NPT (National Pipe Taper) threaded pipe systems. Lock nuts are used to secure fittings, bushings, or conduit connectors in place against a panel, enclosure, or mating fitting surface. The stainless steel construction provides corrosion resistance suitable for wet, outdoor, or chemically exposed environments. At 0.34 inches in length and 1.44 inches in width, this is a compact fastening component. It is installed by plumbers, pipefitters, and HVAC technicians during assembly or service of threaded pipe systems.

This lock nut is suited for residential and light commercial plumbing, HVAC, and industrial piping applications where NPT-threaded connections require a secure, vibration-resistant mechanical lock. It is typically used at panel knockouts, bulkhead fittings, or anywhere a threaded pipe or fitting must be anchored firmly to a surface. The stainless steel material makes it appropriate for corrosive or high-moisture environments where carbon steel hardware would degrade.

Key Features

• Stainless steel construction for corrosion resistance in wet and chemically exposed environments
• NPT end connection for compatibility with standard tapered pipe threads
• Compact profile at 0.34 inches in length and 1.44 inches in width
• Lightweight at 0.05 pounds, suitable for tight or space-constrained installations
• Single-piece unit sold individually for targeted replacement or repair use

Compatibility

Designed as an OEM-style replacement or supplemental hardware for NPT-threaded pipe fitting assemblies in plumbing, HVAC, and industrial piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off the water supply or depressurize the system before servicing any threaded pipe connection. Use an appropriate pipe wrench or spanner to tighten the lock nut securely without over-torquing the fitting. Ensure NPT threads are clean and free of damage before assembly; apply thread sealant tape or compound as required by local plumbing codes.
