The HAM-LET 3102170 is a brass compression tube connector designed to join 3/8-inch OD tubing to a 1/4-inch male NPT threaded port. The fitting transitions from a compression-style tube connection to an MNPT end, making it a common choice in fluid and gas distribution systems where leak-tight, reusable connections are required. Constructed from brass and conforming to ASTM B68 and ASTM B75 standards, this connector is rated to 5000 psi working pressure. Overall length is 1.39 inches. Licensed plumbers, HVAC technicians, and industrial pipe fitters install this type of fitting in instrumentation, refrigeration, and compressed gas line applications.
This connector suits residential and light commercial systems where soft copper or brass tubing terminates at a threaded port. Common applications include refrigerant service lines, compressed air distribution, instrument tubing runs, and hydraulic pilot lines. The compression-style end accepts tubing without soldering or brazing, making field assembly straightforward. It is a recognized equivalent to Swagelok part number B-600-1-2, which may assist in cross-referencing during specification or maintenance work.
Designed as an OEM-style replacement or direct cross to Swagelok B-600-1-2. Suitable for use with 3/8-inch OD soft copper or brass tubing in compression fitting systems terminating at a 1/4-inch MNPT port.
Installation should be performed by a licensed plumber, HVAC technician, or qualified pipe fitter in accordance with applicable local codes and IFGC or IPC requirements. Isolate and depressurize the line completely before disassembly or fitting installation. Do not overtighten the compression nut, as excessive force can deform the ferrule and compromise the seal. Verify that the mating threaded port is clean, undamaged, and compatible with 1/4-inch NPT thread form before assembly.
