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.
(See clamp 149).
N.B. Type 150 cannot be used for tensile loads.
