This replacement sealing element is a core component of the ProPress press pipe joining system, which is widely used by plumbers and pipefitters across residential, commercial, and industrial applications. The sealing element is made from FKM, a high-performance fluoroelastomer material known for its excellent resistance to heat, chemicals, and a wide range of fluids. FKM seals are commonly specified for systems carrying hot water, chemicals, or other demanding media where standard EPDM seals may not be appropriate. This element is sized for 1 inch CTS fittings, making it compatible with standard copper tube size pipe used in plumbing and hydronic heating systems. The black color indicates FKM material, which helps technicians quickly identify the correct seal type during installation or service. Viega ProPress is recognized as the original press pipe joining system. Press connections eliminate the need for open flame soldering, which reduces labor time, improves job site safety, and allows connections to be made on wet or damp pipe. Having the correct replacement sealing element on hand is essential for maintaining and servicing ProPress fittings in the field. If a fitting needs to be reopened or a seal shows wear, replacing the sealing element restores a leak-free, pressure-rated connection. This part is an imported product, consistent with standard industry supply. Trade professionals performing plumbing repairs, new installations, or system retrofits will find this sealing element to be a reliable and straightforward replacement part for keeping ProPress connections performing as designed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFKM fluoroelastomer material provides resistance to heat, chemicals, and demanding fluids\u003c\/li\u003e\n\u003cli\u003eSized for 1 inch CTS Viega ProPress fittings for a precise, reliable fit\u003c\/li\u003e\n\u003cli\u003eBlack color coding makes it easy to identify as FKM for correct material selection on the job\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Viega 17788 ProPress sealing element is a direct replacement part for 1 inch CTS ProPress fittings, built from FKM for chemical and heat resistance.
