The coupler features a 1\/4-18 female NPTF threaded connection with a 1\/4 inch body diameter and an overall length of 2.25 inches. It is rated for a maximum working pressure of 300 psi and handles temperatures ranging from -40 degrees F to 250 degrees F. This fitting is installed by industrial maintenance technicians, HVAC mechanics, and pneumatic system specialists in both commercial and light industrial environments.\u003c\/p\u003e\n\u003cp\u003eThe EZ-251-4FP is suited for use in industrial compressed air systems, pneumatic tool hookups, and fluid transfer lines requiring a reliable quick-disconnect coupler. The industrial interchange design ensures broad cross-compatibility with standard pneumatic hose assemblies. The steel construction makes it appropriate for demanding shop-floor and mechanical room environments where durability and pressure retention are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial interchange coupler type for broad pneumatic system compatibility\u003c\/li\u003e\n  \u003cli\u003eFemale NPTF threaded connection, 1\/4-18 thread size\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in shop and mechanical room use\u003c\/li\u003e\n  \u003cli\u003eCompact 2.25 inch overall length with 0.75 inch hex size for standard wrench 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 industrial interchange pneumatic hose systems using 1\/4 inch body diameter fittings with female NPTF threaded connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician familiar with pneumatic system service. Depressurize the air line and bleed all residual pressure before removing or installing any coupler fitting. Apply thread sealant appropriate for pneumatic service to the NPTF threads and tighten using a wrench on the 0.75 inch hex to avoid damaging downstream hose or fittings. Verify that system operating pressure does not exceed the 300 psi rating of this fitting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: E-Z Mate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchange Type\u003c\/strong\u003e: Industrial\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.256 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: EZ-251-4FP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540992229682,"sku":"EZ-251-4FP","price":84.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c09818d110b99fddd79ffa5d86633b2a.jpg?v=1785867081","url":"https:\/\/voomisupply.com\/products\/parker-ez-251-4fp-pneumatic-hose-coupler-300-psi-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
