This small-diameter service key allows technicians to manually bleed trapped air from hydronic heating and plumbing systems. It fits a 1\/8 inch IPS port and provides a reliable, tool-assisted means of venting air without disassembling the line. Plumbers and hydronic heating technicians keep this type of key on hand as a standard service item when commissioning or maintaining closed-loop systems where air pockets reduce flow efficiency and can cause noise or cavitation.\u003c\/p\u003e\n\u003cp\u003eThis air eliminator key is suited for residential and light commercial hydronic heating systems, radiant floor systems, and plumbing installations where manual air venting is required at a 1\/8 inch IPS bleed port. It is specifically referenced as the correct service key for the B72-140 air eliminator assembly, making it the appropriate replacement or supplemental tool when the original key is missing or damaged.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 1\/8 inch IPS air eliminator bleed port\u003c\/li\u003e\n  \u003cli\u003eDesigned for use with the B72-140 air eliminator\u003c\/li\u003e\n  \u003cli\u003eCompact form factor for use in tight mechanical spaces\u003c\/li\u003e\n  \u003cli\u003eAllows manual air bleeding without system disassembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eReferenced as the correct service key for the OATEY B72-140 air eliminator.

Before bleeding air from the system, reduce system pressure to a safe working level and have an appropriate catch container ready to collect any released fluid. Do not overtighten the bleed port fitting after servicing, as over-torquing the small IPS fitting can damage the seat or threads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePort Size\u003c\/strong\u003e: 1\/8 inch IPS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Air Eliminator Key\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Assembly\u003c\/strong\u003e: B72-140\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: OATEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3sn\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OATEY","offers":[{"title":"Default Title","offer_id":51138325610802,"sku":"3SN","price":36.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305533933.jpg?v=1778253456","url":"https:\/\/voomisupply.com\/products\/oatey-3sn-air-eliminator-key-1-8-inch-ips","provider":"Voomi Supply","version":"1.0","type":"link"}
