ITL was first established in the 1960’s, specialising in the manufacture of special electro-optical tubes for university and science research applications. 

During the 1980’s and 1990’s, ITL expanded rapidly with the introduction of a full range of KF, ISO and Conflat catalogue vacuum hardware flange and fitting components augmented with glass to metal seals, viewports, feedthroughs, ionisation gauge heads and manufacture of custom designed chambers and non-standards.

Since the 1990’s, ITL has developed and maintained several significant key accounts, serving the world leading vacuum equipment suppliers and during this time received a number of achievement recognitions, including Virgin Fastrack 100 and Sussex Business awards.
