Table 2: Identification marking for stainless steel VSH Press fittings
All VSH Press fittings in the sizes DN20 to DN50 (22-54 mm) are equipped with a LBP sealing ring
as standard, to reduce the risk of installation errors.

Thanks to the special grooves in the
O-ring (figure 9) the Leak Before Pressed
O-ring (LBP) ensures optimum control of
the system during pressure testing (such as
for example described in the CEA 4001, no.
17.1.1). Unpressed connections will leak water
resulting in pressure loss and are afterwards
easy to detect (figure 8). During the pressing
procedure the O-ring deforms, closing the
special grooves, and the connection between
the tube and fittings is sealed, ensuring a
water tight connection.

The VSH Press Sprinkler fittings are available either in carbon or in stainless steel. The carbon
steel fittings are manufactured from unalloyed steel (material 1.0034/St 34-2) and are protected
against corrosion by means of a zinc layer (8-15 μm) which is applied by electroplating.
The stainless steel fittings are manufactured from stainless steel (material 1.4404 /AISI 316L).
VSH Press Sprinkler fittings are equipped with an EPDM O-ring as standard in the dimensions
DN20 to DN100 (22-108 mm).
VSH Press Sprinkler fittings are available in the dimensions DN20 to DN100 (22-108 mm).
