It features compression fittings on both ends and is machined from 316 stainless steel, providing strong corrosion resistance in demanding service environments. The single-end shutoff function allows one side of the connection to be isolated when the fitting is disconnected, minimizing fluid loss during service operations. This coupler is rated for a maximum working pressure of 150 psi and is appropriate for licensed plumbers and fluid system technicians working on instrumentation, process, or high-purity tubing installations.\u003c\/p\u003e\u003cp\u003eThis bulkhead coupler is suited for applications where a tube line must pass through a panel, enclosure, or bulkhead wall while maintaining a shutoff capability on one side. Typical installations include instrumentation panels, hydraulic enclosures, and process equipment where controlled disconnection is required. The compression-to-compression configuration supports standard tube outside-diameter connections without the need for solder, flare, or threaded prep work on the tubing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSingle-end shutoff design isolates flow on disconnect to reduce fluid spillage during service\u003c\/li\u003e\n\u003cli\u003eCompression x compression end connections for tool-assisted, leak-resistant tube fittings\u003c\/li\u003e\n\u003cli\u003e316 stainless steel construction for corrosion resistance in harsh or wet environments\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eBulkhead body style allows panel or wall pass-through mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct installation fitting for compression tube systems requiring single-end shutoff bulkhead connections in instrumentation, process, or fluid handling plumbing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified fluid systems technician familiar with compression fitting assembly. Depressurize and drain the affected line completely before removing or installing this coupler. Use appropriate tube cutting and deburring tools to ensure a clean, square tube end before seating into the compression fitting. Follow applicable plumbing codes and fitting manufacturer torque guidance for compression connections to avoid over-tightening and tube deformation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Single End Shutoff Bulkhead Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 316\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 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: 394PSS-6-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541312930098,"sku":"394PSS-6-6","price":440.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24596b9d0e8264e05b560fdf2378b144.jpg?v=1785872139","url":"https:\/\/voomisupply.com\/products\/parker-394pss-6-6-compression-bulkhead-shutoff-coupler","provider":"Voomi Supply","version":"1.0","type":"link"}
