Trelleborg dual-function seals can cut automotive emissions

Trelleborg, Sweden – Trelleborg Sealing Solutions has developed a sealing and damping component to meet the needs of the automotive, truck and transport industry.

Described as a “resilient, dual-function sealing and damping solution”, the D-Seal is designed for static and semi-dynamic powertrain applications where vibrations can cause damage.

According to Trelleborg, D-Seals can extend the time to service intervals of the engine, contributing to lower emissions through improved efficiency.

The D-Seal provides vibration damping in engines and transmissions to prevent damage, making it more effective than traditional designs, said Peter Astrom, product manager, Trelleborg Sealing Solutions.

Trelleborg linked the development to e-mobility and vehicle electrification trends, saying that its new seal “optimises powertrain efficiency and contributes to a reduction in CO2 emissions.”

D-Seals, it added, do not twist in the groove during installation and have no mould or parting line on the sealing surface, removing the risk of failure at the join or a potential leak path.
