IM-PP 599834 0320 ProPress Stainless
2.4.4 Tubing
1 Each tting contains an application specic sealing element. A green
dot on a Viega ProPress Stainless tting indicates the presence of Smart
Connect technology and an EPDM sealing element. A white dot on a
Viega ProPress Stainless tting indicates the presence indicates the
presence of the Smart Connect feature and an FKM 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 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.
1 A 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 An application specic sealing element (FKM or EPDM) ensures water-
tight or air-tight connections.
ProPress 2½" to 4" 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 Press Fittings
Viega stainless steel tubing is oered in ½ inch to 4 inches size in either
304 stainless steel or 316 stainless steel to complement the Viega
ProPress Stainless ttings and oer a complete system solution. Viega
stainless steel tubing meets the requirement of ASTM A312 or ASTM
A554 for Schedule 5 304 and 316 stainless steel pipe.
Only Viega stainless tubing is approved for installation with Viega
ProPress for Stainless ttings. This is to ensure reliability and conformity
with the stainless steel system.
Viega ProPress for Stainless tubing is thicker than Schedule 5 inert gas
welded pipes, meeting ASTM A312, A554, and DIN 1988 wall thickness
requirements.
All diameters are delivered in nominal 20 foot lengths, with a metallic bare
exterior and interior surface. The tubes are free from annealing color and
corrosion-promoting substances.
All tubing has been tested for leaks and is subject to continuous quality
monitoring as well as external monitoring by the material testing oce.
