Part of the KLEENFIT product line, this fitting arrives pre-cleaned and bagged to reduce prep time on the job. The integral stop ensures consistent, repeatable insertion depth, which promotes uniform solder joints and reduces the risk of over-insertion. At 0.054 pounds, it is a compact, lightweight fitting suited for residential and light commercial plumbing rough-in and retrofit work. Licensed plumbers and pipefitters are the typical installers for this type of copper pressure fitting.\u003c\/p\u003e\n\u003cp\u003eThis reducer coupling is used wherever a plumbing system requires a diameter change between 3\/4-inch and 3\/8-inch copper lines. Common applications include supply line transitions, branch connections, and fixture rough-in work in residential construction and remodeling. The KLEENFIT cleaning and bagging process means the fitting interior is ready for flux application and soldering without additional field cleaning steps, making it well suited for high-volume rough-in situations where workflow efficiency matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces from 3\/4 inches to 3\/8 inches copper tubing in a single fitting\u003c\/li\u003e\n  \u003cli\u003eIntegral stop provides consistent insertion depth for reliable solder joints\u003c\/li\u003e\n  \u003cli\u003eKLEENFIT pre-cleaned and bagged — ready for flux and solder without field prep\u003c\/li\u003e\n  \u003cli\u003eC x C (cup by cup) connection compatible with standard sweat-solder methods\u003c\/li\u003e\n  \u003cli\u003eCopper construction for corrosion resistance and long service life in potable water systems\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.054 pounds — minimal load on supply lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style copper pressure fitting for use in standard 3\/4-inch to 3\/8-inch sweat-solder copper plumbing systems in residential and light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and depressurize and drain the line before cutting and fitting. Clean pipe ends and apply flux before soldering; the KLEENFIT pre-cleaned fitting interior eliminates the need to clean the fitting cup but the pipe end still requires standard preparation. Allow the joint to cool fully before restoring water pressure and inspecting for leaks.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModel\u003c\/strong\u003e: 101R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Line\u003c\/strong\u003e: KLEENFIT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: C x C (Sweat Solder)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.46 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.97 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.054 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 683264307193\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: ELKHART PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: COU-34X38\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ELKHART PRODUCTS","offers":[{"title":"Default Title","offer_id":51383892771122,"sku":"COU-34X38","price":31.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312672674.png?v=1782610862","url":"https:\/\/voomisupply.com\/products\/elkhart-products-cou-34x38-reducer-coupling-3-4x3-8-copper","provider":"Voomi Supply","version":"1.0","type":"link"}
