Quality Standards

Tube Clamp fittings are a blackheart malleable iron casting manufactured to BS EN 1562:1997 using grade B32-10 material with a hot dipped galvanised finish to BS EN 1461:1999

All Tube Clamp fitting are supplied with stainless steel grub screws. In order to protect any exposed threads in outdoor installations, we recommend the use of an anti-corrosion galvanising spray such as the one sold as part of our Tube Clamp range. The grub screws can be tightened with an Allen key, however, if fully tightened using a ratchet key to a torque of 4.1kg/m (29ft/lb) the grub screw is capable of withstanding an applied slip load of 900k.
