Ham-let 3001681 Compression Tube Union 316 Ss

Product Description

The HAM-LET 3001681 is a compression tube union fitting manufactured from 316 stainless steel. It connects two tube runs using compression-style end connections on all ports, creating a secure, leak-resistant joint without welding or brazing. This fitting is suited for instrumentation, process, and fluid-handling systems where corrosion resistance and reliable tube-to-tube connections are required. Licensed plumbers, pipefitters, and instrumentation technicians typically install this type of fitting in industrial and commercial applications. The 316 stainless steel construction provides solid resistance to corrosive media and elevated temperatures.

This union fitting is used in plumbing, HVAC, industrial process piping, and instrumentation tubing systems where compression fittings are specified. It is appropriate for both new installation and retrofit work where a removable, re-makeable tube connection is needed. The three-port compression configuration allows inline tube joining with full disassembly capability. Applications include compressed gas lines, hydraulic instrumentation circuits, and chemical-compatible fluid lines in residential, commercial, and light industrial settings.

Key Features

• 316 stainless steel construction for corrosion resistance in aggressive media and environments
• Compression x compression x compression end connections on all ports for tool-assisted, weld-free assembly
• Union design allows full disassembly and re-make without cutting tube
• Cross-referenced to Swagelok part number SS-1210-3-12-8 for direct replacement sourcing
• Single-piece package quantity suitable for individual repair or low-volume installation work

Compatibility

Cross-referenced to Swagelok part number SS-1210-3-12-8. Designed as an OEM-style compression tube union for inline tube connections in systems specifying compression-style stainless steel fittings.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified instrumentation technicians. Depressurize and isolate the line completely before disassembling or installing any compression fitting. Follow the fitting manufacturer's make-up procedure for compression joints, typically involving hand-tight plus a specified number of wrench turns, and consult applicable codes such as ASME B31.1 or ASME B31.3 for process piping installations. Do not over-tighten compression fittings, as this can deform the ferrule and compromise the seal.
