The fittings require no soldering or brazing and are installed with electro-hydraulic press tools (battery-powered or corded press tools).
Product Information 2.
Product Information 2.3.1 Commercial and Residential ProPress systems are approved for numerous applications in commercial and residential markets including potable water. “Zero Lead” identifies products meeting the lead-free requirements of NSF 61 through testing under NSF/ANSI 372 (0.25% or less maximum weighted average lead content). 2.3.2 Industrial and Plant Operations ProPress systems are also suitable for use in industrial and plant processes.
Product Information 2.4.2 Listings and Certifications The fittings have the following listings and certifications: ■ ABS: American Bureau of Shipping Type Approval ■ ASME B16.51: Copper and Copper Alloy Press-Connect Pressure Fittings ■ ASME B31.1: Power Piping ■ ASME B31.3: Process Piping ■ ASME B31.9: Building Service Piping ■ BV: Bureau Veritas Type Approval ■ Canadian Registration Number (CRN): 0A14541.
Product Information 2.4.4 Copper Tubing Copper tubing must be free of surface imperfections, including metal stamped print lines, before a ProPress fitting is installed. Viega ProPress may only be pressed onto copper tube in accordance with ASTM B88 or B75. When pressing onto B88 copper tube, types K, L, and M may be used. Tempers O60 and O50, known as “soft copper”, are limited to nominal sizes ½" to 1 ¼". Temper H58, known as hard copper, may be used with nominal sizes ½" to 4".
Product Information 2.4.5.3 EPDM Sealing Element Viega ProPress fittings are manufactured with a high-quality, shiny black EPDM (Ethylene Propylene Diene Monomer) 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 2.4.5.6 Cylindrical Guides All Viega fittings are designed with cylindrical guides to keep the tube straight and protect the sealing element during assembly. 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 2.4.5.8 Viega Smart Connect Technology 1 Identify an unpressed connection during pressure testing when water or air flows past the sealing element. 2 Upon identification, use the press tool to press the fitting, making a secure leakproof connection. 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 2.5.2 Expansion Thermal expansion in installed systems generates stress on tubing and appliance connectors. Compensation must be allowed for expansion and contraction that may occur within the tubing. Expansion joints or mechanical expansion compensators may be used to alleviate these stresses. ProPress systems do not require any additional protection as compared to a soldered system.
Product Information 2.5.5 Underground Installations Viega ProPress fitting systems with copper tubing are approved for underground installations. However, installations must meet all state and local codes, including those for underground. Proper authorization must be obtained prior to installation from the Authority Having Jurisdiction. 2.5.6 Concealed Spaces The Viega ProPress fitting system has been approved for use in concealed spaces.
Product Information 2.5.8 Pressure Surges ■ ProPress fittings should be isolated or separated by sufficient distance from pumps, fast-acting valves, and other sources of pressure transients. ■ The maximum operating pressure in a ProPress system is 200 psi, which applies to general operation as well as pressure transients. ■ Good engineering practices should be used to design the system in a way that minimizes sharp pressure surges.
Product Information 2.5.10.1 Controlling Deflection Deflection while pressing can be minimized by utilizing the following installation practices. Alternate Press Directions ▶ Press one end of fitting. ▶ Make second press on other end of fitting from the opposite side. Site conditions permitting. Push-Pull Method ▶ Rings = Push on press tool. ▶ Jaws = Pull on press tool. The press tool can be feathered using the trigger as needed to apply pulling or pushing force to control deflection.

Installation Instructions ▶ Carefully reach past the grip ring, pinch and remove the sealing element from the fitting. WARNING! Grip ring is extremely sharp, use gloves or extreme caution when reaching into fitting. CAUTION! If reusing the sealing element ensure the sealing element does not make contact with grip ring as this can cause damage. ▶ Visually inspect replacement sealing element. Ensure there are no defects, scratches, or burrs, is free of debris, and is coated with lubricant.
Installation Instructions 4.2 Installing and Mounting the Tube Observe the general rules of hanging and mounting: ■ Fixed tubing should not be used as support for other tubing and components. ■ Do not use pipe hooks. ■ Observe distance between fittings and mounting points. ■ Observe the expansion direction – plan fixed and sliding mounts. 4.2.1 Pipe Hangers and Supports Tubing supports perform two functions: ■ To provide support for the tubing. ■ To guide the tube during thermal expansion and contraction.
Installation Instructions 4.3.1 Transition Fittings 4.3.1.1 Threaded Connections The Viega ProPress systems can be joined with off-the-shelf threaded fittings made of non-ferrous metals. In this regard: ■ The threaded connection is made first. ■ The press connection is made second. This process avoids unnecessary torsion on the press fitting. 4.3.1.2 Flange Connections When using Viega flanges, bolt the flange end in place prior to pressing the fitting to the tube. 4.3.
