These 42mm Key Clamps are designed to fit 42.4mm outer diameter tube. Industry standard 1.1/4" Galvanised Nominal Bore tube is the standard tube that is recommended for use with these fittings. However, any tube within the 41-43mm range in most solid materials should suffice. If you are unsure that a tube that you already have and would like to use will fit, give us a ring and we will try to determine if it will suit.
