The HAM-LET 3001644 is a compression tube union designed to join two compression-end tube connections in a single inline fitting. Manufactured from 316 stainless steel to ASTM A182, A213, A269, A276, and A479 standards, it delivers corrosion resistance suited to demanding fluid and gas service. The fitting measures 1.94 inches in overall length and weighs 0.25 pounds. It is well suited for instrument tubing, process lines, and other applications where a reliable leak-tight union is required. Licensed plumbers, pipefitters, and instrumentation technicians are the typical installers.
This union fitting is used in residential and commercial applications where two compression tube ends must be connected or rejoined without welding. Common install scenarios include instrument tubing runs, hydraulic lines, refrigeration-adjacent instrument lines, and process piping that requires periodic disassembly. The compression x compression end configuration allows tool-assisted connection on both sides without special tooling beyond standard tube-fitting wrenches. Operating temperature range is -20 degrees F minimum to 37 degrees F maximum per published ratings.
Cross-references to Swagelok part number SS-1010-6-6. Designed as an OEM-style replacement or direct-fit option for compression tube union applications requiring 316 stainless steel construction to the listed ASTM and DIN standards.
Installation should be performed by a qualified pipefitter or instrumentation technician. Depressurize and isolate the tubing system fully before disassembly or fitting installation. Use appropriate tube-fitting wrenches and follow the fitting manufacturer torque guidance; do not overtighten compression fittings by hand. Verify tube end preparation, including squareness and deburring, before seating the ferrule to ensure a leak-free connection.
