Built with Smart Connect technology, the fitting allows installers to visually confirm an unconnected fitting before system pressurization, reducing the risk of missed connections. The body is manufactured from copper containing a minimum of 99.9% copper, meeting ASTM B88 tube compliance standards. At 0.5 inch by 0.5 inch sizing and weighing just 0.08 pounds, this coupling is a compact, reliable component suited for tight spaces and high-volume installations where speed and code compliance are both priorities.\u003c\/p\u003e\n\u003cp\u003eThis coupling is used in potable water plumbing systems where a press-fit, no-stop coupling is required. The no-stop design allows the fitting to slide freely along the pipe, which is useful during repositioning or in repair scenarios where a standard shoulder stop would interfere. It is appropriate for residential and light commercial plumbing applications and is commonly installed by licensed plumbers working with copper pipe systems. The ProPress connection method eliminates open flame, making it suitable for fire-sensitive environments and occupied spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSmart Connect technology enables visual identification of unpressed fittings before system pressure test\u003c\/li\u003e\n  \u003cli\u003eNo-stop design allows free pipe travel through the fitting for flexible positioning during installation\u003c\/li\u003e\n  \u003cli\u003eManufactured from copper with a minimum of 99.9% copper content per ASTM B88\u003c\/li\u003e\n  \u003cli\u003eComplies with California Lead Law AB1953 and VT193 requirements\u003c\/li\u003e\n  \u003cli\u003eConforms to NSF-61, Annex G weighted average lead content evaluation at 0.25% maximum\u003c\/li\u003e\n  \u003cli\u003eFlameless press-fit connection reduces fire risk and speeds up installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style press-fit replacement coupling for 1\/2 inch copper pipe plumbing systems using the Viega ProPress connection platform.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before cutting pipe or positioning the fitting. Use only a compatible Viega ProPress jaw tool sized for 1\/2 inch fittings to make the press connection. Inspect each fitting with Smart Connect technology before pressurizing the system to confirm all connections have been fully pressed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1\/2 inch x 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper (minimum 99.9% copper, ASTM B88)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: ProPress press-fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Plumbing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Compliance\u003c\/strong\u003e: NSF-61 Annex G, AB1953, VT193\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: VIEGA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 78172\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VIEGA","offers":[{"title":"Default Title","offer_id":51138454913330,"sku":"78172","price":26.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305528021.jpg?v=1778256907","url":"https:\/\/voomisupply.com\/products\/viega-78172-propress-copper-coupling-no-stop-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
