Fittings that go with the tubes: clamps to fix a tube to a frame or to another tube, end caps to close an open bore, and aluminium sleeves to stop a clamp or bolt crushing a thin wall.

Everything here is sized off the tube. Clamps and caps go by the tube's outside diameter; reinforced sleeves go by the inside diameter. We have written which is which on each product page because it is the single most common way to order the wrong part.

Most fittings list the full size range in one place, so if you are building a frame that mixes 16mm and 20mm tube you can order both here.
