{"product_id":"bs-b-fa-7r-rupture-disc-holder-3-inch-flange-150-lb","title":"BS\u0026B FA-7R Rupture Disc Holder 3 Inch Flange 150 LB","description":"\u003cdiv\u003eThe BS\u0026amp;B FA-7R Rupture Disc Holder is a Quik-SERT, reduced outside diameter, flat-faced safety head engineered to sit between ANSI flanges in a 3\" line with an ANSI 150 rating. It accepts a 3\" rupture disk and companion flange, and its compact design nests between flange studs for easy, between-flange installation. The FA-7R is intended to be clamped between the inlet and outlet with standard gasketed flange hardware to establish a secure seating and seal for a forward-acting rupture-disk assembly. As part of BS\u0026amp;B’s solid-metal disk family, the FA-7R works with Type B disks in BS\u0026amp;B safety-head configurations, delivering overpressure protection while allowing relatively quick disk replacement without dismantling piping. This holder is well-suited for space-constrained installations in chemical processing, oil and gas, and power-generation facilities where a 3\" disk size and 150 lb class flanges are specified, providing a robust, code-compliant path to venting when the disk ruptures. Its flat-faced interface and reduced OD help minimize clearance issues, enabling reliable operation in tight plant skids and between standard ANSI flanges while maintaining BS\u0026amp;B’s established safety-head performance.\u003c\/div\u003e","brand":"BS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677410787630,"sku":null,"price":43.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f5b1b42e-41f4-4f99-8109-4ea1066a5a13.jpg?v=1769562522","url":"https:\/\/plgautomation.com\/products\/bs-b-fa-7r-rupture-disc-holder-3-inch-flange-150-lb","provider":"PLG Automation ","version":"1.0","type":"link"}
