Built from steel with a zinc chromate finish, this coupler provides a secure, corrosion-resistant connection between air supply lines and pneumatic tools or equipment. It features a 1\/2 inch body diameter and accepts a 3\/4 inch hose ID, making it suited for medium-flow pneumatic circuits. The NPTF threaded connection ensures a pressure-tight seal without the need for additional sealant tape in properly machined fittings. This type of fitting is typically installed by HVAC technicians, industrial maintenance mechanics, and pneumatic system specialists.\u003c\/p\u003e\u003cp\u003eThis coupler is intended for industrial pneumatic applications where a reliable hose barb connection is required. Common install scenarios include air compressor outlet lines, pneumatic tool drops, and plant-floor air distribution plumbing. The steel construction and zinc chromate finish make it suitable for both shop and light industrial environments where moisture and mild corrosion exposure are a concern. It ships as a single unit and is appropriate for both new installations and replacement of worn or damaged couplers in existing pneumatic lines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSteel body with zinc chromate finish for corrosion resistance\u003c\/li\u003e\n\u003cli\u003e1\/2 inch coupler body diameter for medium-flow pneumatic lines\u003c\/li\u003e\n\u003cli\u003e3\/4 inch hose ID barb connection for secure hose retention\u003c\/li\u003e\n\u003cli\u003eNPTF threaded interface for a leak-resistant pressure seal\u003c\/li\u003e\n\u003cli\u003eCompact, single-piece coupler construction for straightforward installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for industrial pneumatic hose assemblies requiring a 1\/2 inch hose barb coupler with NPTF threaded connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with pneumatic system plumbing. Depressurize and lock out the air supply before removing or installing any coupler. NPTF threads are designed for a dry-seal fit, but verify thread condition and mating port integrity before assembly. Follow applicable shop air and pneumatic plumbing standards for your jurisdiction when sizing and routing supply lines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose ID\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Zinc Chromate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\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: 0.71 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-501-12HB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542331031858,"sku":"EZ-501-12HB","price":113.88,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb56ce312f69214c0dfa28675ce300b6.jpg?v=1785898409","url":"https:\/\/voomisupply.com\/products\/parker-ez-501-12hb-pneumatic-hose-barb-coupler-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
