Sized at 3\/4 inch crimp-fit (CF) on the barb end and 1\/2 inch male pipe thread (MPT) on the other, this fitting provides a reliable mechanical connection without the need for specialized push-to-connect tools. Rated for potable water distribution and hydronic heating applications, the UC138LFA meets ASTM F1807, NSF\/ANSI 61, and NSF 372 standards, confirming lead-free construction and suitability for drinking water contact. Licensed plumbers and pipefitters install this adapter during new construction or retrofit work where PEX tubing transitions to a threaded fitting or valve body.\u003c\/p\u003e\u003cp\u003eThis adapter is suited for potable water supply lines and hydronic heating loops in residential and light commercial installations. The barb end accepts connection via a stainless steel clamp system or a copper crimp ring system — both sold separately. It is a practical, low-cost solution wherever a PEX run must terminate at a male-threaded component such as a valve, manifold port, or threaded fitting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLead-free DZR brass construction meets NSF 372 requirements for drinking water applications\u003c\/li\u003e\n\u003cli\u003e3\/4 inch CF barb end compatible with stainless steel clamp or copper crimp ring systems\u003c\/li\u003e\n\u003cli\u003e1\/2 inch MNPT threaded end for connection to standard pipe threads\u003c\/li\u003e\n\u003cli\u003eApproved for potable water distribution and hydronic heating use\u003c\/li\u003e\n\u003cli\u003eMeets ASTM F1807 and NSF\/ANSI 61 standards\u003c\/li\u003e\n\u003cli\u003eSingle-piece, low-profile design simplifies installation in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in potable water distribution and hydronic heating applications.

Shut off the water supply and relieve system pressure before cutting into existing lines or making connections. Use the appropriate crimp or clamp tool rated for the ring system being used — do not attempt to seat the barb without the correct installation tool, as an improperly seated connection can fail under pressure. Inspect the barb and tubing end for burrs or debris before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarb End Size\u003c\/strong\u003e: 3\/4 inches CF (Crimp-Fit)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread End Size\u003c\/strong\u003e: 1\/2 inches MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Lead-Free DZR Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.109 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ASTM F1807, NSF\/ANSI 61, NSF 372\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RWC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: UC138LFA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RWC","offers":[{"title":"Default Title","offer_id":51344171991346,"sku":"UC138LFA","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551238.jpg?v=1782030636","url":"https:\/\/voomisupply.com\/products\/rwc-uc138lfa-3-4-in-cf-x-1-2-in-mpt-brass-pex-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
