Machined from steel with a zinc chromate finish, it features a 3\/8-18 MNPT thread and a 3\/8 inch body diameter. The connector measures 1.91 inches in overall length and carries a maximum working pressure rating of 300 psi. It follows the Industrial Interchange standard, making it a widely accepted fitting format across pneumatic tooling and equipment. Licensed HVAC technicians, pipefitters, and maintenance mechanics regularly use couplings of this type when assembling or servicing compressed-air distribution lines and pneumatic control circuits.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for industrial and commercial environments where threaded NPT connections are required on pneumatic hose assemblies. The Industrial Interchange profile is one of the most common coupling standards found on pneumatic tools, air compressors, and shop-floor distribution systems. It installs into standard 3\/8-18 NPT female ports and mates with corresponding Industrial Interchange bodies and plugs. Single-piece packaging makes it a practical replacement or add-on fitting for maintenance stock.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial Interchange coupling type — compatible with the most widely used pneumatic coupling standard\u003c\/li\u003e\n  \u003cli\u003e3\/8-18 MNPT thread for direct installation into standard NPT female ports\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\u003e1.91 inch overall length with 0.69 inch hex size for wrench engagement\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type — no special tooling required beyond a standard wrench\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Industrial Interchange connector fitting for pneumatic hose assemblies using 3\/8-18 NPT threaded ports.

Apply thread sealant tape or compound to the MNPT threads in accordance with the system manufacturer and applicable plumbing or pneumatic code requirements. Use a properly sized wrench on the 0.69 inch hex to tighten — do not use the hose or coupling body as a lever. After installation, pressure-test the connection and inspect for leaks before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.91 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.69 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\u003eInterchange Type\u003c\/strong\u003e: Industrial\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: Zinc Chromate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0912 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: H2E\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542382903602,"sku":"H2E","price":24.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d0049c5899cb99f20770db152441ed3.jpg?v=1785899228","url":"https:\/\/voomisupply.com\/products\/parker-h2e-pneumatic-hose-coupling-3-8-18-mnpt-industrial","provider":"Voomi Supply","version":"1.0","type":"link"}
