15MM TO 108MM SIZES

The XPress jointing system has been designed with easy, efficient installation in mind. XPress Copper, XPress Stainless,
XPress Carbon, XPress Copper Gas, XPress Stainless Gas and XPress Solar have common installation instructions.

To ensure the fittings stay clean and the

only remove the fitting from its packaging 15 20 20 20 10 50 50 50
immediately prior to installation.

The tube can be fully inserted by hand. A
damaged tube end will require excessive 22 21 21 21 10 52 52 52
force to be used. If this is the case you should
check the tube is round and deburred before 28 23 23 23 10 56 56 56
continuing. Check the O ring is not damaged. 35 26 26 26 10 62 62 62
XPress fittings with plain male ends must not
be used directly with capillary fittings, since 42 30 30 30 20 80 80 80

Heat should not be applied to XPress 64 - - 50 30 - - 130
fittings, directly or indirectly. They should be
disconnected (where applicable) to avoid any 66.7 - 50 50 30 - - 130
possible damage to non-metallic parts if they 76.1 55 55 50 55 165 165 140
are to be used on a system in conjunction
with capillary fittings. Similarly, reconnection 88.9 63 63 64 65 186 186 193
must not be considered until the heated 108 77 77 64 80 234 234 208
