Product Information 2.4.5.3 FKM Sealing Element Viega ProPress 304 FKM fittings are manufactured with a high-quality, dull black FKM (Fluoroelastomer) sealing element installed at the factory. The molded sealing lips also seal tube surfaces with slightly uneven surfaces. Sealing elements are inserted into the fitting using a H1 food grade lubricant registered with NSF and the USDA, and is approved for use under FDA 21 CFR.
Product Information Fittings that do not have cylindrical guides risk making an unsecured connection. Without the guides, installers may damage the sealing element. Fittings are radially pressed around the sealing element in a single step. 2.4.5.
Product Information 2.4.5.7 Viega Smart Connect Technology 1 Identify an unpressed connection during pressure testing when water or air flows past the sealing element. Viega Smart Connect technology provides the installer quick and easy identification of an unpressed fitting during a leak test. When the fitting is pressed, a secure, non-detachable, mechanical connection is created.
Product Information 2.5 General Installation Requirements The Viega ProPress Stainless fitting system must be installed while considering the following general industry requirements. 2.5.
Product Information 2.5.3 Electrical Bonding When properly installed, ProPress Stainless fittings comply with Section 1211.15 Electrical Bonding and Grounding of the Uniform Plumbing Code and Section 310 of the International Fuel Gas Code. The mechanical press provides continuous metal-to-metal contact between fitting and tube. The press ensures the continuity of the bonding through this contact. A qualified electrician is responsible for ensuring electrical bonding is tested and secured.
Product Information 2.5.6 Concealed Spaces The Viega ProPress Stainless fitting system has been approved for use in concealed spaces. Specific performance tests were conducted to evaluate the fittings for use in concealed spaces. Concealed tubing and fittings shall be protected from puncture threats. 2.5.7 Corrosion Protection Viega ProPress Stainless fittings exposed to corrosive action, such as soil conditions or moisture, must be protected in an approved manner in accordance with NFPA 54 Section 404.
Product Information 2.5.9 Rotating a Pressed Fitting Once a ProPress Stainless fitting has been pressed, it can be rotated (not by hand), but once rotated more than five degrees, the fitting should be repressed to restore resistance to rotational movement. If the fitting is re-pressed, care should be taken to align the flat sides on the jaw with those on the fitting. 2.5.10 Deflection The pressing process can cause deflection (angular misalignment) to occur.
Product Information Re-Press ▶ Press the fitting, once on each side (that is, re-press the fitting a second time on the opposite side). Pressing the same connection from the opposite side will usually straighten misalignment between the tube and fitting. ■ When pressing overhead piping, it may be inconvenient to alternate sides for each press. ■ The natural weight of the piping plus pressing on opposite sides at a 45 degree angle should adequately eliminate deflection.

Installation Instructions 4.6 Cutting the Tube Damaged tube and/or sealing element Press fittings can form improper connections as the result of damaged tube and/or sealing elements. ■ Do not use flame cutters when cutting the tube. ■ Do not use grease or oils when cutting the tube. Only cut stainless steel pipe with an approved stainless steel pipe cutter. ▶ Cut the tube square using a displacement-type cutter or fine toothed saw.
Installation Instructions 4.8 Pressing the Fitting WARNING! Read and understand all instructions for installing Viega ProPress Stainless fittings. Failure to follow all instructions may result in extensive property damage, serious injury, or death. 4.8.1 Viega ProPress Stainless ½" to 2" Installation For use with Viega stainless steel tubing in ½ inch to 2 inches. ▶ Check the sealing element for correct fit: ■ The tube end is not bent or damaged. ■ The tube is deburred.
Installation Instructions No-stop couplings and extended no-stop couplings are often used to conduct repairs. Without a stop, these couplings can slide completely onto a tube and allow a connection to be made in tighter spaces. Unlike fittings with an integrated stop that have a minimum insertion depth, nostop couplings have minimum and maximum allowable insertion depths. Both the minimum and the maximum insertion depths must be marked and a line connecting the two marks.
Installation Instructions ▶ Open the jaw and place at right angle on the fitting. ▶ Look at insertion depth mark on the tube to make sure that the tube is properly inserted into the fitting. ▶ Hold trigger on press tool until press jaws have fully engaged the fitting. Jaws will automatically release after a full press is made. WARNING!
