150 - Internal Expanding Joint (Self Colour)
A straight fitting for joining tubes of the same size. This fitting can only be used for 3.25mm wall thickness tube (1”, 1 1/4” & 1 1/2” BS EN 10255, formerly BS 1387, medium weight) and must not be used as a load bearing joint, particularly for tensile loads. Type 149, which has superior load characteristics, may sometimes be used as an alternative.
Please note that these fittings are bare metal and will be naturally prone to rusting unless a protective coating such as a lacquer is applied.
