Featuring a 3\/8 inch NPTF connection, this coupler is built to maintain consistent flow rates while forming a pressure-tight threaded seal. The NPTF thread form creates a mechanical seal on the threads themselves, reducing reliance on thread sealant tape alone. Licensed plumbers and gas fitters install this type of fitting during new construction, system retrofits, or service calls where a reliable threaded coupling is required at 3\/8 inch line connections.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for residential and light commercial gas piping applications where a 3\/8 inch NPTF threaded coupling is specified. It is sold individually and is appropriate for natural gas and propane distribution lines where the installer requires a high flow path through the fitting. Typical installation scenarios include manifold connections, appliance supply drops, and branch line terminations in both new and existing piping systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch NPTF thread provides a pressure-tight mechanical seal without relying solely on thread sealant\u003c\/li\u003e\n  \u003cli\u003eHigh flow design supports full line capacity at the 3\/8 inch connection point\u003c\/li\u003e\n  \u003cli\u003eCompact, single-piece construction suited for tight installation spaces\u003c\/li\u003e\n  \u003cli\u003eSold individually, allowing single-unit replacement or system expansion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation coupling for gas piping systems requiring a standard 3\/8 inch NPTF threaded coupler.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or gas fitter in accordance with applicable local codes and the IFGC. Shut off the gas supply and verify zero pressure at the connection point before disassembling or installing any fitting. Apply an appropriate thread sealant rated for gas service to all NPTF threads prior to assembly. Do not over-tighten threaded connections; follow the fitting manufacturer and local code guidance for proper make-up.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/8 inch NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Type\u003c\/strong\u003e: High Flow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.754 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662459922465\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: WILLIAMS COMFORT PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8RH38D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51345575706930,"sku":"8RH38D","price":113.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310542708.jpg?v=1782061091","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-8rh38d-high-flow-coupler","provider":"Voomi Supply","version":"1.0","type":"link"}
