It features a 1\/4-inch female pipe thread (FPT) on one end and a 1\/2-inch male pipe thread (MPT) on the other, allowing a transition between two different thread sizes at the point of penetration. The fitting uses a 3\/4-16 UNS thread for the bulkhead locknut interface and measures 2.16 inches in length. Constructed from brass, it offers corrosion resistance suitable for water, air, and many compatible fluid systems. Plumbers and mechanical contractors install this type of fitting where lines must pass cleanly through a wall or tank surface.\u003c\/p\u003e\n\u003cp\u003eThis bulkhead connector is appropriate for residential and light commercial plumbing, HVAC auxiliary drain or condensate applications, and fluid-system panel installations where a secure, leak-resistant wall penetration is required. The dual-size thread configuration makes it useful when the supply-side and outlet-side piping are different nominal sizes. The all-brass construction supports installations in moderate-temperature, moderate-pressure service conditions typical of these trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-inch FPT inlet connects to standard female-threaded pipe or tubing fittings\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch MPT outlet provides a larger-diameter threaded male connection on the exit side\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 UNS bulkhead thread secures the fitting through panel or tank walls\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in water and air service\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 2.16 inches in length suits tight panel clearances\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 1 allows single-unit procurement for service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation bulkhead connector for systems requiring a 1\/4-inch FPT to 1\/2-inch MPT panel penetration fitting with a 3\/4-16 UNS locknut thread interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed plumber or qualified mechanical contractor should install this fitting in accordance with applicable IPC or local plumbing code requirements. Shut off the fluid or gas supply and relieve system pressure fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape to the male threads before assembly and tighten to hand-tight plus the manufacturer-recommended turns without over-torquing the brass threads. Inspect the installation for leaks before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/4 inches FPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/2 inches MPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBulkhead Thread\u003c\/strong\u003e: 3\/4-16 UNS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 1.3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.355 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 129A-391FC2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67950449361202,"sku":"129A-391FC2","price":15.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/491b2e45b0d66625969048be17e8ef85.jpg?v=1791718179","url":"https:\/\/voomisupply.com\/products\/midland-industries-129a-391fc2-bulkhead-connector-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
