The valve body is machined from brass for corrosion resistance and durability in demanding shop and industrial environments. It uses NPT threading with a 1\/2-inch male inlet and a 1\/4-inch female outlet, and seals with Buna Nitrile O-rings suited for air and light petroleum-based fluid service. At 0.3 pounds, this compact valve measures 4 inches tall and 3.5 inches in both width and length. Installed by licensed pipefitters, plumbers, and industrial maintenance technicians, it maintains system pressure within safe operating limits by diverting flow when pressure exceeds the set point.\u003c\/p\u003e\n\u003cp\u003eThis valve is used in compressed air distribution lines, pneumatic tool supply systems, and hydraulic or fluid transfer circuits where overpressure protection is required. Typical installations include compressor bypass circuits in light industrial and commercial facilities. The 1\/2-inch male NPT inlet suits standard shop-air piping, while the 1\/4-inch female NPT outlet connects to smaller downstream lines or relief ports. It is packaged individually and suited for both new installation and in-field replacement of worn or failed bypass valves.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass valve body resists corrosion in air and light fluid service\u003c\/li\u003e\n  \u003cli\u003eNPT threads on both inlet and outlet for standard pipe fitting compatibility\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch male NPT inlet and 1\/4-inch female NPT outlet configuration\u003c\/li\u003e\n  \u003cli\u003eBuna Nitrile O-rings provide reliable sealing against air and petroleum-based fluids\u003c\/li\u003e\n  \u003cli\u003eCompact form factor at 4 inches height and 3.5 inches width and length\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.3 pounds for easy handling and installation in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or new-installation pressure bypass valve for compressed air and fluid control systems using standard 1\/2-inch male NPT inlet connections and 1\/4-inch female NPT outlet connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pipefitter, plumber, or industrial maintenance technician. Depressurize and lock out the system before removing any existing valve or fitting. Apply thread sealant or PTFE tape to NPT threads per standard trade practice and applicable plumbing or mechanical codes. Do not overtighten brass fittings, as the material is subject to thread damage under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Pressure Bypass Valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFemale Thread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: Buna Nitrile\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\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: PRO-SOURCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3555510084PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51736184521010,"sku":"3555510084PRO","price":29.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a261a6eee5ca300455928d406459f2b.jpg?v=1788776405","url":"https:\/\/voomisupply.com\/products\/pro-source-3555510084pro-pressure-bypass-valve-brass-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
