This coupling connects two R20-threaded components using a nut-style engagement, providing a secure, leak-resistant joint at transition or extension points in a piping run. Licensed plumbers and hydronic heating installers are the typical tradespeople who work with this fitting during system assembly or repair. The R20 thread standard is common in European-style PEX and multilayer pipe systems, making this coupling appropriate for residential and light commercial hydronic applications.\u003c\/p\u003e\n\u003cp\u003eThis coupling is suited for use in radiant floor heating systems, plumbing distribution manifolds, and other hydronic piping configurations that rely on R20-threaded connections. It is used wherever two R20-nut fittings must be joined inline, such as during pipe extensions, repairs, or manifold assembly. The fitting is intended for use with compatible UPONOR piping and fittings that share the R20 thread specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR20 x R20 configuration joins two R20-threaded components inline\u003c\/li\u003e\n  \u003cli\u003eNut-style coupling design allows for controlled tightening and a secure seal\u003c\/li\u003e\n  \u003cli\u003eCompatible with R20-threaded PEX and multilayer pipe fittings\u003c\/li\u003e\n  \u003cli\u003eSuited for radiant heating and plumbing distribution applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or system fitting for use with R20-threaded UPONOR piping components in hydronic heating and plumbing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified hydronic heating technician. Shut off system water supply and relieve pressure before making any connections. Use appropriate R20 tooling or wrenches to tighten the nut fitting to the manufacturer-specified feel without over-torquing. Follow all applicable local plumbing codes and system manufacturer guidelines during installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: R20 x R20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Coupling with Nut\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: UPONOR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: a4322020\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UPONOR","offers":[{"title":"Default Title","offer_id":51233407893810,"sku":"A4322020","price":150.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633999.jpg?v=1780099307","url":"https:\/\/voomisupply.com\/products\/uponor-a4322020-coupling-r20-x-r20-nut","provider":"Voomi Supply","version":"1.0","type":"link"}
