The HAM-LET 3101065 is a brass compression tube plug designed to seal the open end of a compression-style tubing line. Constructed from brass meeting ASTM B68 and ASTM B75 standards, this plug terminates a tube run without the need for soldering or threading. It uses a standard compression fitting end connection, making installation straightforward with common hand tools. The part weighs 0.25 pounds and is sold as a single unit. It is suited for closed-end sealing applications in instrumentation, fluid distribution, and light process piping where compression fittings are already in use.
This compression tube plug is appropriate for residential and light commercial systems where tube lines must be capped during service, testing, or system reconfiguration. It is commonly installed by plumbers, HVAC technicians, and instrumentation technicians working on copper or compatible tubing systems. The rated temperature range runs from -4 degrees F to 98.6 degrees F (-20 degrees C to 37 degrees C), keeping it within the bounds of typical low-pressure fluid and gas service applications.
Designed as an OEM-style compression tube plug compatible with standard compression tube fitting systems. Cross-reference Swagelok part number B-600-P for equivalent fitment verification.
Installation is performed by a licensed plumber or qualified instrumentation technician. Depressurize and isolate the tubing line completely before removing any existing fitting or inserting this plug. Use appropriately sized tube cutters and deburring tools to ensure a clean, square tube end before seating the compression ferrule. Follow applicable IPC or ASME B31 guidelines for the specific fluid service involved.
