About us

TST started out as a manufacturing partner to RUTAB, Sweden's leading supplier of cable and pipe entries.  From the very beginning, our main focus has been innovative production techniques and products.
Our offices and production facility are located in Nässjö, in south central Sweden - one of the country's major logistical centers.

We put a lot of focus and effort in creating products that bring added value to the customer/user - one should benefit from using our cable seals.  The aim is to continue to push the boundaries of conventional production and mould technology, as a leading innovator in the cable and pipe entry market.

TST is a family owned and managed company and has been so since it was founded.
