The compression fitting style allows tool-assisted assembly without soldering or flaring, making it suitable for use in refrigeration, pneumatic, and fluid transfer applications. Constructed from brass, the fitting offers good corrosion resistance and compatibility with a wide range of tubing materials. Licensed HVAC technicians, plumbers, and fluid system installers are the typical end users for this type of fitting.\u003c\/p\u003e\u003cp\u003eThis bulkhead union is used in applications where tubing must pass through a bulkhead or panel in residential and light commercial systems. Common install scenarios include refrigerant line routing through equipment enclosures, compressed air distribution panels, and hydraulic or pneumatic control cabinets. The fitting is sold in a package quantity of six units, making it suitable for multi-point installations or stocking purposes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction provides corrosion resistance and durability in fluid and pneumatic systems\u003c\/li\u003e\n\u003cli\u003eCompression fitting design eliminates the need for soldering or flaring during installation\u003c\/li\u003e\n\u003cli\u003eBulkhead configuration allows tubing to pass cleanly through panels or enclosures\u003c\/li\u003e\n\u003cli\u003eCompatible with standard compression tubing used in HVAC, plumbing, and pneumatic applications\u003c\/li\u003e\n\u003cli\u003eSold in a package of 6 units for multi-point or stocking use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation compression bulkhead union suitable for use in systems requiring panel or enclosure tubing pass-through connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed technician familiar with compression fitting assembly and applicable plumbing or refrigeration codes. Shut off system pressure and depressurize all lines before removing or installing fittings. Hand-tighten the compression nut before applying a final wrench turn per standard compression fitting practice — avoid overtightening, which can distort the ferrule and cause leaks. Verify tubing is cut cleanly and deburred before insertion to ensure a proper seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Bulkhead Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Style\u003c\/strong\u003e: Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 66NBH-6-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538588729650,"sku":"66NBH-6-6","price":138.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60785e6c8ac0b80034b0227184087e11.jpg?v=1785825204","url":"https:\/\/voomisupply.com\/products\/parker-66nbh-6-6-brass-compression-bulkhead-union","provider":"Voomi Supply","version":"1.0","type":"link"}
