Constructed from brass, this coupler features a 1\/4-18 male NPT threaded end and a 0.25 inch body diameter. It is used to connect pneumatic hoses and air tools to supply lines, providing quick and secure coupling in both workshop and industrial settings. HVAC technicians, pipefitters, and general mechanical contractors install this type of fitting as part of pneumatic control and compressed air distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for residential and light commercial pneumatic applications where a universal-style coupler is required. It is commonly installed on compressed air lines, pneumatic tool connections, and control system air supplies. The male NPT thread allows straightforward installation into female-threaded ports on regulators, manifolds, hose assemblies, and related pneumatic components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUniversal coupler design compatible with common pneumatic hose fittings\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in compressed air service\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 male NPT thread for standard pipe thread connections\u003c\/li\u003e\n  \u003cli\u003e0.25 inch body diameter suits common pneumatic hose and fitting sizes\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.21 pounds for easy handling and installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation coupler for pneumatic systems using 1\/4-18 NPT male threaded connections and standard universal coupler interchange.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed pipefitters, HVAC technicians, or qualified mechanical contractors. Depressurize and bleed down the air supply line completely before removing or installing any pneumatic fitting. Apply thread sealant tape or pipe thread compound to the NPT threads in accordance with the fitting manufacturer recommendations and applicable codes. Do not overtighten brass fittings, as the material can crack under excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.21 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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UC-251-4MP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538779177266,"sku":"UC-251-4MP","price":52.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d23cfaec326bc3f53587abe1e384e78.jpg?v=1785826515","url":"https:\/\/voomisupply.com\/products\/parker-uc-251-4mp-universal-pneumatic-hose-coupler","provider":"Voomi Supply","version":"1.0","type":"link"}
