How To Measure End Caps

Caps are a relatively simple product to measure, sharing many similarities with Tube Inserts in the sense that the most important measurements to consider are the Outside Diameter and Internal Diameter.

Firstly, to start measuring you want to find the outer measurement of your application. This is done by working out the distance between both of the outer lips of your object. (See image below)

Secondly, once you have the outer measurement correct you want to match this up with the internal figure detailed on-site. Matching up your outside with the internal measurement will provide a tight and secure fitting. 

Due to the materials used, you may find that certain products have the ability to stretch across a range of diameters, preventing the need for an exact measurement.

Please refer to the images below for a visual representation.
