XPRESS STAINLESS GAS FEATURES
XPress Stainless Steel Gas is optimised for use Manufactured from 316 stainless steel
as a system. Fittings are manufactured from 316 Available in sizes 15 to 108mm
(BS 316S31/DIN 1.4401) or 316 Ti (BS 320531/DIN Designed for use with XPress stainless
1.4571). The fittings incorporate a yellow HNBR steel system tube
(Hydrogenated Acrylonitrite Butadiene Rubber) For use in internal and external above
O ring. XPress Stainless Steel Gas fittings do not ground 2nd and 3rd family gas services
have the LBP feature for safety reasons. (see page 136) – where we locate the

and 3rd family gas services and available in sizes permits or costly insurance
from 15 to 108mm. BSI verified
XPress Stainless Gas fittings are approved for use
at temperatures from -20 to 70°C. The maximum
working pressure inside buildings is 1bar and
maximum working pressure outside buildings is
5bar (maximum test pressure 7.5bar).
XPress Stainless Steel Gas fittings are marked
with a highly visible yellow label stating Gas on
each fitting.
As part of the DVGW/BSI (formerly GL, British
Gas) approvals process, XPress Stainless Gas
fittings have passed the High Temperature
Leakage Rate test at 650°C for 30 minutes at
PN5/GT1.

XPRESS SOLAR FEATURES
XPress Copper Solar fittings are manufactured Manufactured from copper/copper alloy
from copper and copper alloy and incorporate a Available in sizes 15 to 54mm
green FPM (Fluorocarbon rubber/FPM Viton™) Leak Before Press
O ring and incorporate the unique “Leak Before Suitable for high temperature solar
Press” (LBP) design. This feature means that any applications
assembled joints inadvertently left unpressed will Electrical continuity assured when
exhibit a leak during system testing. This enables XPress joint complete
contractors to easily identify unpressed fittings Clean, heat free jointing
before commissioning. Safety - no naked flames, no hotwork
XPress Copper Solar fittings are available in sizes permits or costly insurance
15 to 54mm and are marked with a highly visible Temperature rating -20 to 200°C
label stating Solar on each fitting, to confirm that Pressure rating 10bar maximum working
solar fittings have been installed once crimped. pressure
Designed for use in solar applications and
for use with most proprietary ethylene glycol
and propylene glycol heat transfer fluids in
concentrations of up to 40%.
