This sealing element is made from FKM, a high-performance fluoroelastomer material known for its resistance to heat, chemicals, and aggressive fluids. It is sized for 3\/4 inch pipe connections and is finished in black, consistent with FKM identification standards used across the ProPress product line. Plumbers and pipefitters working with copper tube size press fittings rely on sealing elements like this one to maintain leak-free joints over the long term. Whether you are replacing a worn element during a maintenance call or stocking components for a large commercial installation, having the correct OEM sealing element on hand is essential. The Viega ProPress system is the original press pipe joining technology and has been trusted by trade professionals for decades. Press connections eliminate open flame, reduce labor time, and create consistent, reliable joints compared to traditional soldering methods. The 17778 sealing element is specifically engineered to fit ProPress CTS fittings, ensuring proper compression and sealing performance when the fitting is pressed. FKM sealing elements are well suited for use in systems carrying hot water, chemicals, and hydrocarbons, making them a preferred choice over standard EPDM elements in applications where fluid compatibility is a concern. HVAC technicians, plumbing contractors, and mechanical installers working on residential and commercial hydronic systems will find this part to be a direct, code-compliant solution. Keeping replacement sealing elements in your service kit minimizes downtime and keeps press tool operations running smoothly on the job site.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFKM fluoroelastomer material provides excellent resistance to heat, chemicals, and aggressive fluids\u003c\/li\u003e\n\u003cli\u003eSized for 3\/4 inch Viega ProPress CTS fittings for a precise, leak-free press connection\u003c\/li\u003e\n\u003cli\u003eBlack color coding identifies FKM material for quick identification in the field\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Viega 17778 sealing element is an OEM-grade FKM replacement component for 3\/4 inch ProPress CTS fittings, delivering reliable sealing performance for plumbing and mechanical professionals working with press pipe joining systems.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 17778\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: FKM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Fitting System\u003c\/strong\u003e: Viega ProPress CTS Fitting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin\u003c\/strong\u003e: Import\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VIEGA","offers":[{"title":"Default Title","offer_id":51120814063922,"sku":"17778","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304884859.jpg?v=1777740242","url":"https:\/\/voomisupply.com\/products\/viega-17778-propress-sealing-element-3-4-inch-fkm-black-for-propress-cts-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
