Ham-let 3001648 Compression Tube Union 316 Ss

Product Description

The HAM-LET 3001648 is a compression tube union fitting designed to join two compression-end tube connections in a single inline assembly. Constructed from 316 stainless steel and manufactured to ASTM A182, ASTM A213, ASTM A269, ASTM A276, and ASTM A479 standards, this union provides a leak-tight mechanical connection without the need for soldering or welding. At 2.11 inches overall length and weighing 0.25 pounds, it is compact enough for tight installations. Licensed plumbers, pipefitters, and instrumentation technicians use this fitting in fluid and gas handling systems where corrosion resistance and repeatable tube sealing are required.

This compression union is suited for residential and commercial applications where stainless steel tubing must be connected or disconnected without special tooling. Typical install scenarios include instrumentation lines, process tubing runs, HVAC refrigerant-adjacent sensing lines, and light industrial fluid systems. The compression-by-compression end configuration allows the fitting to be positioned mid-line as a union, making tube removal and reinstallation straightforward during maintenance cycles. The fitting meets DIN EN10122-5 and DIN EN10272 material standards in addition to the listed ASTM specifications, making it appropriate for applications requiring internationally recognized material traceability.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or instrumentation technician familiar with compression fitting assembly procedures. Depressurize and isolate the line completely before disconnecting or installing any compression fitting. Follow the tube preparation guidelines appropriate to the tubing outside diameter to ensure proper ferrule seating and leak-free makeup. Refer to applicable codes such as ASME B31.1 or B31.3 for process and power piping applications.
