Please read and understand the instructions before beginning installation
to eliminate safety concerns and reduce risks associated with use and
handling of Viega products.
Viega ProPress systems are state-of-the-art press 󶈵tting systems
that provide economical and reliable installations for the commercial,
industrial, and residential markets.
Viega ProPress are copper and zero lead bronze 󶈵ttings and valves in
copper tube size (CTS) ranging from ½ inch to 2 inches for ProPress
󶈵ttings and 2½ inches to 4 inches for ProPress XL-C® (Copper) 󶈵ttings.
The 󶈵ttings require no soldering or brazing and are installed with electro-
hydraulic press tools (battery-powered or corded press tools).
The 󶈵ttings feature a green dot representing Smart Connect® technology
with an EPDM sealing element suitable for many applications. Viega’s
unique, patented Smart Connect technology helps installers ensure that
they have pressed all connections.

2.4.4 Press Fittings
2.4.4.1 Viega ProPress Fittings
1 Each 󶈵tting contains an application speci󶈵c sealing element. A green
dot on a Viega ProPress 󶈵tting indicates the presence of Smart
Connect technology and an EPDM sealing element.
2 Viega’s distinctive hexagonal pressing pattern bonds 󶈵tting and tube
and provides the mechanical strength for the connection.
3 Color coded dots indicate the presence of Viega’s unique, patented
Smart Connect technology which helps installers ensure that they
have pressed all connections.
4 Cylindrical guides ensure the proper insertion of the tube and protects
the sealing element.

2.4.4.2 Viega ProPress XL-C Fittings
Viega ProPress 󶈵ttings 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 󶈵tting using a H1
food grade lubricant registered with NSF and the USDA, and is approved
for use under FDA 21 CFR.
The EPDM sealing element possesses excellent resistance to aging,
ozone, sunlight, weathering, environmental in󶈶uences, and most alkaline
solutions and chemicals used in a broad range of applications.
The operating temperature of the EPDM sealing element is 0° to 250°F
(-18° to 120°C).
2.4.4.3 EPDM Sealing Element
1 The 420 stainless steel grip ring's teeth cut into the tube and lock the
󶈵tting securely in place.
2 A PBT (Polybutylene Terephthalate) separator ring protects the sealing
element from damage by creating a positive physical separation during
installation and later during pressing.
3 The EPDM sealing element ensures water-tight or air-tight connections.
ProPress XL-C 󶈵ttings are designed to be pressed with ProPress XL-C press
rings and V2 actuator to produce a non-detachable, secure connection.

2.4.5 Copper Tubing
Copper and copper alloy 󶈵ttings are compatible with ½ inch to 1¼ inches soft
copper tubing and ½ inch to 4 inches hard copper tubing types K, L, and M. All
copper tubing that is to be used must comply with ASTM B88 standards.
Copper tubing must be free of surface imperfections,
including metal stamped print lines, before a ProPress
󶈵tting is installed.
