This elbow conforms to the ASTM F1960 standard, meaning it is installed using an expansion tool and ring — not a crimp or clamp method. The fitting connects two 3\/4-inch PEX-A lines at a right angle and is used to route water supply lines around corners in both hot and cold water distribution applications. Licensed plumbers and pipefitters handling PEX-A rough-in work are the primary installers of this fitting.\u003c\/p\u003e\u003cp\u003eThe 642WP3 is suited for residential and light commercial potable water supply systems where PEX-A tubing is specified. It is commonly installed during new construction or remodel rough-in when the plumber needs to change direction in a water supply run. The F1960 expansion connection style provides a reliable, leak-resistant joint when the correct expansion ring and PEX-A tubing are used together. Both hot and cold water supply lines are typical applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eF1960 expansion-style connection — compatible with PEX-A tubing only, not PEX-B or PEX-C\u003c\/li\u003e\n\u003cli\u003e90-degree elbow geometry for right-angle direction changes in supply runs\u003c\/li\u003e\n\u003cli\u003e3\/4-inch by 3\/4-inch sizing for standard residential water supply line diameter\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction provides corrosion resistance in potable water systems\u003c\/li\u003e\n\u003cli\u003eConforms to ASTM F1960 standard for expansion-type PEX fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3\/4-inch PEX-A tubing in ASTM F1960 expansion-style plumbing systems.

Shut off the water supply and depressurize the line before beginning any fitting work. This fitting should be installed by a licensed plumber in accordance with the applicable local plumbing code and IPC requirements. Do not use this fitting with PEX-B or PEX-C tubing, as the expansion method is specific to PEX-A material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: F1960 Expansion (PEX-A)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Angle\u003c\/strong\u003e: 90 Degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3\/4 inch x 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASTM F1960\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 739236423856\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 642WP3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIOUX CHIEF","offers":[{"title":"Default Title","offer_id":51383857840434,"sku":"642WP3","price":33.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312673936.png?v=1782609691","url":"https:\/\/voomisupply.com\/products\/sioux-chief-642wp3-f1960-pex-a-90-degree-elbow-3-4-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
