Introducing the Mild Steel 150 Internal Joiner Sleeve, a straight fitting designed to seamlessly join tubes of the same size. Specifically designed for 3.25mm wall thickness tubes (1", 1 1/4" & 1 1/2" BS EN 10255, formerly BS 1387, medium weight), this joiner sleeve offers a reliable and secure connection. It is important to note that this fitting is not suitable for use as a load bearing joint, particularly for tensile loads. For applications requiring superior load characteristics, type 149 may be used as an alternative.
