Brass (BSB) British Standard Brass

Brass tubing has a uniform wall thickness, irrespective of the tube diameter, therefore any thread cut on, or in, it needs to have the same depth, so 26 TPI is standard on all BSB diameters.
BSB is often confused with BS Cycle thread, the difference being that brass thread has an angle of 55° whereas Cycle is 60°.
