Swagelok M-600-1-4 Tube Fitting

Swagelok M-600-1-4 is a straight tube fitting from the Alloy 400/R-405 family that serves as a male connector between 3/8 in. outside-diameter tubing and a 1/4 in. MNPT threaded port. The body is manufactured in Alloy 400 (R-405), a nickel–copper alloy known for its corrosion resistance in demanding fluid-system applications. This Swagelok component is specified as a straight male connector with a 3/8 in. tube OD to 1/4 in. MNPT interface, making it suitable for joining 3/8 in. tubing to standard 1/4 in. NPT ports in instrumentation, process equipment, and other fluid-handling configurations. As part of Swagelok’s line of straight fittings, the M-600-1-4 is designed to integrate with Swagelok tubing systems and be used in setups where a reliable, metal-to-thread connection is required between a 3/8 in. tube and a 1/4 in. NPT port. This part number—M-600-1-4—identifies the alloy, connection style, and size combination (3/8 in. tube OD x 1/4 in. MNPT) for precise selection within Swagelok’s broad family of tube fittings.
