The HAM-LET 3001042 is a three-way compression tube union constructed from 316 stainless steel. It joins tubing runs at a single junction point using compression fittings on all three ends, creating a leak-resistant connection without soldering or welding. The all-compression design allows for installation and removal using standard hand tools, making it practical for maintenance-intensive systems. This fitting is suited for plumbing, instrumentation, and process piping applications where corrosion resistance and secure tubing connections are required. Licensed plumbers and instrumentation technicians are the typical installers.
This union fitting is used in residential and commercial plumbing systems, as well as industrial instrumentation and fluid transfer lines. The 316 stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or elevated temperatures where standard brass or carbon steel fittings would degrade. All three compression end connections allow it to serve as a branch or union point within a tubing run without requiring permanent joints.
Designed as an OEM-style replacement or new-installation fitting for compression tube systems requiring a three-port union connection in 316 stainless steel.
This fitting is typically installed by licensed plumbers or instrumentation technicians working on tubing systems. Shut off and depressurize the line completely before removing or installing any compression fitting. Ensure tubing ends are cut cleanly and squarely, and deburr before inserting into the compression fitting to achieve a proper seal. Follow applicable IPC or facility piping codes for pressure ratings and inspection requirements.
