Trapped air in a closed-loop system causes noise, reduced flow, and heat-transfer loss. This vent gives technicians a reliable, manual means of bleeding air from high points in the system, radiators, baseboard convectors, and similar terminal units. The compact 1\/8-inch connection size fits standard service ports and bleed valves found across residential and light-commercial hydronic installations.\u003c\/p\u003e\n\u003cp\u003eThe 110-337 is suited for use in hot water heating systems, chilled water loops, and radiant floor circuits where air accumulation is a recurring service issue. It installs at high points in the piping system, at radiator or convector bleed ports, or wherever a manual purge point is needed. Hydronic service technicians and licensed plumbers will encounter this fitting in new-construction and retrofit applications alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/8-inch connection size fits standard bleed port fittings on radiators, convectors, and manifolds\u003c\/li\u003e\n  \u003cli\u003eManual operation gives the technician direct control over air-purging without automatic valve components to maintain\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suits tight installation spaces at terminal units and high-point purge ports\u003c\/li\u003e\n  \u003cli\u003eManufactured in Italy to T-75 product standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style manual air vent for 1\/8-inch bleed ports on hydronic heating and cooling terminal units and piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or hydronic heating technician. Before servicing, shut down the circulator pump and reduce system pressure to a safe working level. Use an appropriate thread sealant rated for hydronic service on the 1\/8-inch male threads. Follow applicable plumbing codes, including IPC guidelines, for closed-loop hydronic system service and repair.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: Italy\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: LEGEND VALVE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 110-337\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LEGEND VALVE","offers":[{"title":"Default Title","offer_id":51467611111730,"sku":"110-337","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/313945282.jpg?v=1783907979","url":"https:\/\/voomisupply.com\/products\/legend-valve-110-337-manual-air-vent-1-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
