It accepts compression fittings on both ends, creating a secure, leak-resistant joint without soldering or threading. Rated to 1500 psi maximum working pressure and sized for 3\/8 inch outside diameter tubing, this union is built for demanding service in refrigeration, HVAC, and fluid-system applications. Plumbers, refrigeration mechanics, and HVAC technicians install this fitting where a straight union connection is needed between two compression tube runs.\u003c\/p\u003e\n\u003cp\u003eThis union is suited for residential and light commercial installations involving copper or compatible tubing at 3\/8 inch OD. Typical applications include refrigerant line repairs, water supply connections, and instrument tubing assemblies where a reliable compression-style union is required. The all-brass construction resists corrosion and holds up in wet or humid environments common to mechanical rooms and utility spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x compression end connections for tool-accessible, solder-free assembly\u003c\/li\u003e\n  \u003cli\u003eRated to 1500 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/8 inch outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in wet and humid service environments\u003c\/li\u003e\n  \u003cli\u003eInline union configuration for straight tube-to-tube joining\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and service fitting for compression tube systems using 3\/8 inch outside diameter tubing with standard compression connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or HVAC technicians following applicable IPC or IMC guidelines. Shut off and depressurize the line before disassembly or fitting installation. Hand-tighten the compression nut onto the tube, then advance with a wrench per standard compression fitting practice — do not overtighten, as excessive torque can deform the ferrule and cause leaks. Pressure-test the connection before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 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\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 165HD-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538282217778,"sku":"165HD-6","price":24.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/769668134aed859bf055516c572fe641.jpg?v=1785821697","url":"https:\/\/voomisupply.com\/products\/parker-165hd-6-compression-tube-union-3-8-in-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
