This fitting creates a straight, inline union in tubing runs where a secure, leak-resistant joint is required without soldering or threading. Rated to 2100 psi maximum working pressure, the 165HD-4 is built for demanding fluid and gas handling applications. It is installed by plumbers, HVAC technicians, and refrigeration mechanics who require a reliable mechanical tube connection in tight spaces or field-service situations.\u003c\/p\u003e\n\u003cp\u003eThis compression union is suited for use in residential and light commercial plumbing, HVAC refrigerant or fluid lines, and pneumatic or hydraulic tubing systems where compression fittings are the specified connection method. Its brass construction provides corrosion resistance and durability across a wide range of compatible tube materials and media. The fitting is packaged individually and is appropriate for service and repair work as well as new installation runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eCompression x compression end connections on both sides for tool-assisted, no-solder installation\u003c\/li\u003e\n  \u003cli\u003e2100 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eStraight union configuration for inline tube joining\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suitable for confined installation areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube union compatible with standard compression tubing systems in plumbing, HVAC, and fluid handling applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed plumbers or qualified HVAC and refrigeration technicians. Before installation, shut off and depressurize the line completely. Use appropriate tube cutters and deburring tools to ensure a clean, square tube end before seating the compression ferrule. Follow applicable IPC or IFGC guidelines for fitting torque and joint inspection; do not overtighten, as this can damage the ferrule and compromise the seal.\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 2100 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\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-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540595310898,"sku":"165HD-4","price":47.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6436825923197bb2de4ad397a7808597.jpg?v=1785859518","url":"https:\/\/voomisupply.com\/products\/parker-165hd-4-brass-compression-tube-union-2100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
