Ham-let 3500167 Compression Tube Nut 3/4 in Fnpt 316 Ss

Product Description

The HAM-LET 3500167 is a compression tube nut designed for use in high-pressure tubing assemblies where a secure, leak-resistant connection is required. Manufactured from 316 stainless steel, this fitting nut meets ASTM A182, ASTM A213, ASTM A269, ASTM A276, and ASTM A479 standards, as well as DIN EN10122-5 and DIN EN10272. It accepts 3/4 inch outside diameter tubing with a female NPT (FNPT) thread connection and is rated for a maximum working pressure of 4600 psi. The overall length is 0.69 inches. This component is installed by licensed plumbers, pipefitters, and instrumentation technicians working on fluid and gas distribution systems.

This compression tube nut is suited for industrial, commercial, and process instrumentation applications where corrosion resistance and pressure integrity are critical. Typical installations include instrument tubing runs, chemical process lines, compressed gas systems, and hydraulic circuits operating within the rated temperature range of -20 degrees F to 37 degrees C. The FNPT thread configuration makes it compatible with standard NPT-threaded fittings and valve bodies commonly found in these systems.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or instrumentation technician following applicable codes such as ASME B31.1 or B31.3 for pressure piping. Depressurize and isolate the system completely before disassembling any tubing connections. Use appropriate wrenches sized for the fitting hex; do not use pliers or tools that may damage the seating surfaces. Inspect tubing ends for squareness and burrs before assembly to ensure a proper compression seal.
