It features a 3\/8 inch MNPT thread and a 1\/4 inch body diameter, built to Industrial Interchange standards for broad compatibility across air tool and hose setups. Constructed from nickel-plated steel, the 1503 delivers corrosion resistance and reliable sealing under typical shop and field air pressures. Licensed HVAC techs, plumbers, machinists, and general maintenance professionals use this fitting when assembling or servicing pneumatic lines that require a secure, quick-disconnect-ready threaded connection.\u003c\/p\u003e\u003cp\u003eThis coupling is suited for light industrial, commercial shop, and maintenance environments where Industrial Interchange pneumatic fittings are the standard. It connects air hoses to tools, manifolds, blow guns, and other pneumatic accessories via standard NPT threaded ports. The 1\/4 inch body size is common in air tool applications operating at typical shop air pressures. Its compact size and low weight make it practical for both permanent installations and portable air setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndustrial Interchange coupling type for broad cross-brand compatibility\u003c\/li\u003e\n\u003cli\u003e3\/8 inch MNPT thread connects to standard NPT-ported equipment and fittings\u003c\/li\u003e\n\u003cli\u003e1\/4 inch body diameter suits common air tool and hose configurations\u003c\/li\u003e\n\u003cli\u003eNickel-plated steel construction resists corrosion in shop environments\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight at 0.07 pounds for easy handling and 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 pneumatic systems using Industrial Interchange standard couplings with 3\/8 inch NPT threaded connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified maintenance technicians or trade professionals working on compressed air systems. Depressurize and bleed the air line completely before removing or installing any pneumatic fitting. Apply appropriate thread sealant to NPT threads and tighten to hand-tight plus the number of turns appropriate for the pipe size per standard practice — do not overtighten steel fittings into aluminum or plastic ports. Consult applicable facility safety codes when modifying compressed air distribution lines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Connector\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: MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inches\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: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Nickel-Plated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COILHOSE PNEUMATICS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1503\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51689041887538,"sku":"1503","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cfa32e069b73b4b50e73bab2b9b3c2e6.jpg?v=1788254153","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-1503-pneumatic-hose-coupling","provider":"Voomi Supply","version":"1.0","type":"link"}
