The size of all our tube insert products is based on the outside size of the tube they fit into. Please follow the below guidance to select the correct item. For assistance, please contact our sales department 01282 424376 [email protected]
OUTSIDE SIZE OF TUBE: Measure the external size of your tube, eg if this is 25mm square the correct product would be part 3981/1 (25mm Sq Ribbed Insert 1.0-3.0mm WT).
TUBE WALL THICKNESS: Sometimes referred to as 'gauge size' and listed in some of the product tables as 'WT'. This is the thickness of the tube wall, the ribs on the inserts will suit a range of tube wall thickness. To check the insert will fit the tube inside size minus 2 x wall thickness from the tube outside size.
