Conforming to the ASTM F1960 standard, this fitting connects via cold-expansion rings rather than crimp or clamp methods, producing a joint that cold-expands back to its original diameter around the fitting for a secure, leak-resistant connection. Plumbers and pipefitters working with PEX-A tubing use this elbow to make directional changes in tight spaces without reducing flow. It is suitable for both hot and cold water supply lines in residential and light commercial construction.\u003c\/p\u003e\n\u003cp\u003eThe 642WP2 is intended for 1\/2 inch PEX-A tubing installed under ASTM F1960 expansion fittings protocols. Typical applications include domestic hot and cold water distribution, in-wall rough-in work, under-slab installations, and radiant heating supply and return legs where a 90 degree direction change is required. The polyphenylene body resists corrosion and scale buildup, making it well-suited for both chlorinated municipal water and closed-loop hydronic circuits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eASTM F1960 cold-expansion connection method for a strong, permanent joint on PEX-A tubing\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch fitting size fits standard 1\/2 inch PEX-A tubing\u003c\/li\u003e\n  \u003cli\u003e90 degree elbow geometry for directional changes in water distribution runs\u003c\/li\u003e\n  \u003cli\u003ePolyphenylene construction resists corrosion, scale, and chemical attack\u003c\/li\u003e\n  \u003cli\u003eCompatible with potable hot and cold water systems and closed-loop hydronic applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation fitting for 1\/2 inch PEX-A piping systems installed to the ASTM F1960 expansion fitting standard.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation requires an ASTM F1960-rated expansion tool and the appropriate size expansion ring placed on the PEX-A tubing before expanding. Shut off the water supply and depressurize the line before cutting or joining any piping. Work should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local codes. Do not use crimp or clamp tools with F1960 expansion fittings, as they are not interchangeable with other PEX connection methods.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Standard\u003c\/strong\u003e: ASTM F1960 cold expansion\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTubing Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConfiguration\u003c\/strong\u003e: 90 degree elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Polyphenylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 739236423849\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: SIOUX CHIEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 642WP2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIOUX CHIEF","offers":[{"title":"Default Title","offer_id":51383980163378,"sku":"642WP2","price":27.67,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673896.png?v=1782613955","url":"https:\/\/voomisupply.com\/products\/sioux-chief-642wp2-1-2-inch-f1960-pex-a-90-degree-elbow","provider":"Voomi Supply","version":"1.0","type":"link"}
