It uses compression-style end connections on each end, eliminating the need for soldering or flaring. The fitting carries a 3\/8-inch NPTF thread size, an inside diameter of 0.338 inches, and is rated for a maximum working pressure of 150 psi. The temperature range runs from -40 degrees F to 200 degrees F. Plumbers, HVAC technicians, and fluid system installers working with tube runs through enclosures or equipment panels are the primary users of this fitting.\u003c\/p\u003e\n\u003cp\u003eThis bulkhead union is suited for residential and commercial plumbing, HVAC, and pneumatic or hydraulic tube routing applications where tubing must pass cleanly through a structural surface. Its brass construction makes it compatible with typical copper or compatible synthetic tubing installations. It meets D.O.T. FMVSS571.106, SAE J1131, and SAE J246 standards, making it appropriate for applications requiring certified fluid-handling components. Single-unit packaging makes it practical for service calls and repair work where one fitting is needed.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x compression end connections on both sides for tool-friendly, solder-free installation\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and durability in fluid-handling environments\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eWide service temperature range: -40 degrees F to 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch NPTF thread size with 0.338-inch inside diameter\u003c\/li\u003e\n  \u003cli\u003eCertified to D.O.T.

Before installing or replacing this fitting, shut off the relevant fluid or pneumatic supply and depressurize the line completely. Compression fittings require proper tube squareness and seating of the ferrule against the fitting body — do not overtighten, as this can deform the ferrule and cause leaks. Always verify the tubing outside diameter is compatible with the fitting before final assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Bulkhead Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.338 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: D.O.T.
