This small but critical component restricts vent flow to meet indoor installation requirements under applicable gas codes, allowing regulators to be installed in spaces where open venting to atmosphere is not permitted. Licensed gas technicians and HVAC service professionals install this part as part of a compliant regulator assembly in residential and light commercial gas systems.\u003c\/p\u003e\n\u003cp\u003eThe 12a39 vent limiting orifice is specifically designed for the Maxitrol 325 Series regulator line. It threads into or mounts at the regulator vent port, limiting the release of gas in the event of a diaphragm failure to levels acceptable under ANSI and local gas codes. This makes it a necessary component when a 325 Series regulator is installed indoors or in a confined space rather than vented directly to the outside.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned as a vent limiting orifice for the Maxitrol 325 Series gas pressure regulator\u003c\/li\u003e\n  \u003cli\u003eAllows indoor installation of regulators by limiting vent discharge per applicable gas codes\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement for the 325 Series vent port\u003c\/li\u003e\n  \u003cli\u003eCompact form factor for installation in tight equipment spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Maxitrol 325 Series gas pressure regulators as a vent limiting orifice.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed gas technician or qualified HVAC professional. Shut off the gas supply and verify zero pressure at the regulator before removing or installing any vent port components. Consult the applicable edition of the IFGC or your local gas code for indoor regulator venting requirements. Do not over-tighten the orifice fitting, as damage to the regulator vent port threads may compromise the seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Vent limiting orifice for 325 Series gas pressure regulator\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: HONEYWELL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12a39\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51233308115250,"sku":"12A39","price":50.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307632961.png?v=1780096960","url":"https:\/\/voomisupply.com\/products\/honeywell-12a39-vent-limiting-orifice-325-series","provider":"Voomi Supply","version":"1.0","type":"link"}
