It transitions from a 1 inch female thread on the larger end to a 3\/8 inch female thread on the smaller end. Constructed from brass, this coupling provides solid corrosion resistance and reliable sealing in a wide range of fluid-handling applications. Licensed plumbers and mechanical contractors install this type of fitting when a pipe run must change diameter at a joint without additional adapters or unions.\u003c\/p\u003e\n\u003cp\u003eThis reducing coupling is suited for residential and light commercial plumbing, hydronic heating, compressed air, and similar threaded piping systems where a direct pipe-size reduction is needed at a coupling point. It is appropriate for use in water supply lines, distribution manifolds, and equipment connections that require a transition from 1 inch to 3\/8 inch pipe thread.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 1 inch to 3\/8 inch in a single fitting, eliminating the need for a separate adapter\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance suitable for water, air, and compatible fluid service\u003c\/li\u003e\n  \u003cli\u003eThreaded connection type for standard NPT installation with no special tooling\u003c\/li\u003e\n  \u003cli\u003eCompact coupling profile keeps the piping assembly tight and low-profile\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation brass reducing coupling for standard 1 inch x 3\/8 inch threaded pipe connections in residential and commercial plumbing and mechanical systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing or installing any threaded fitting. Apply thread sealant tape or paste to the male threads before assembly and tighten to snug with a pipe wrench, avoiding overtightening that can crack brass fittings. Inspect for leaks after restoring system pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLarge End Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\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: MATCO-NORCA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: b-rc0502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MATCO-NORCA","offers":[{"title":"Default Title","offer_id":51138286747954,"sku":"B-RC0502","price":22.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305526662.png?v=1778252555","url":"https:\/\/voomisupply.com\/products\/matco-norca-b-rc0502-brass-reducing-coupling-1x3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
