It ruptures at 140 psig when exposed to 72°F (22°C) and is fabricated from 316 stainless steel, providing corrosion resistance for demanding process environments. The disk carries the part number 4-140-72-316SS and is designed for use in liquid or gas service where a precise, engineered burst pressure is required to safeguard vessels and piping by venting downstream of the disk. When installed in the appropriate BS\u0026amp;B head, it delivers reliable, predictable opening characteristics at the specified temperature and pressure conditions. \u003c\/p\u003e\u003c\/div\u003e","brand":"BS\u0026B","offers":[{"title":"New","offer_id":51677412524334,"sku":null,"price":65.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f3c0f9f8-2f65-45f2-a6f3-a72a58e59903.jpg?v=1769562547","url":"https:\/\/plgautomation.com\/products\/bs-b-safety-systems-4-140-72-316ss-rupture-disc","provider":"PLG Automation ","version":"1.0","type":"link"}
