Gaskets

Innovative Fluid Sealing

We are delighted to announce that we have been appointed the official UK agents for Triangle Fluid Controls Ltd.

Triangle Fluid Controls Ltd are a market driven, technology based company serving customer worldwide with innovative sealing products. They manufacture and distribute filled-PTFE, compressed non-asbestos sheets/gaskets and semi-metallic gaskets. Our commitment to quality and service ensures that our customers receive high quality products in the shortest lead time possible. TFC offers design, engineering, technical and sales support, to both end users and distributors.

All of their products are tested throughout the manufacturing process by their onsite laboratory staff to provide consistency and traceability to our/their customers. This also applies to our line of metallic gaskets. All of these product lines are marketed under the Durlon® brand name..

Durlon® Sealing Products have the widest possible range of service applications, therefore, the number of gaskets required to be inventoried can be greatly reduced. This impacts process safety because limiting the number of gasket styles reduces the change of installing the wrong gasket in the wrong service. For these reasons more and more original manufacturers and industrial consumers are specifying Durlon® gasket materials for their needs.

Service & Cost Savings

Unsurpassed seal ability drastically lowers emission levels
General purpose sheet out performs traditional economy sheets
