Built to the Industrial Interchange standard, this connector features a 1\/4-inch body diameter and a 3\/8-18 female NPTF thread connection. The body is steel with a zinc chromate finish for corrosion resistance. Rated to 300 psi maximum working pressure, it is suited for shop air systems, pneumatic tool lines, and light industrial pneumatic circuits. Licensed HVAC techs, plumbers, and general contractors working with compressed air distribution will find this a direct-fit, standard-specification coupling connector.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in residential and light commercial compressed air systems where Industrial Interchange-pattern quick-connect fittings are the shop or facility standard. Typical installations include air compressor outlet lines, pneumatic tool drops, and in-line hose connections where a threaded female port is required. The 3\/8-18 NPTF thread provides a pressure-tight seal without the need for additional sealant tape in most applications, though field practice varies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial Interchange pattern for broad compatibility with standard pneumatic quick-connect systems\u003c\/li\u003e\n  \u003cli\u003eFemale NPTF 3\/8-18 thread for a pressure-tight mechanical seal\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eSteel construction with zinc chromate finish for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch body diameter and 1.6-inch overall length for compact inline installation\u003c\/li\u003e\n  \u003cli\u003e0.81-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 connector for compressed air systems using the Industrial Interchange quick-connect coupling standard with 3\/8-18 female NPTF threaded ports.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician after depressurizing and locking out the compressed air system. Use a correctly sized open-end or adjustable wrench on the 0.81-inch hex to avoid fitting damage. Consult applicable facility safety codes and the compressor manufacturer guidelines when integrating into existing pneumatic distribution lines. Inspect the mating thread and port for damage or contamination before assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 Interchange\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: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.81 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\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\u003eWeight\u003c\/strong\u003e: 0.078 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\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: H3C-E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540837007666,"sku":"H3C-E","price":16.69,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/760887d7fca3089566aa40a4d928f9de.jpg?v=1785864603","url":"https:\/\/voomisupply.com\/products\/parker-h3c-e-pneumatic-hose-coupling-1-4-in-female-nptf","provider":"Voomi Supply","version":"1.0","type":"link"}
