Trelleborg's enhanced D-shaped seal designs lower automotive emissions

Source:Adsale Plastics Network Date :2022-06-28 Editor :JK

Trelleborg Sealing Solutions launches its enhanced double D-Seal, a resilient, dual-function sealing and damping solution specifically developed to meet the needs of the automotive, truck, and transportation industry.

 

Designed specifically for static and semi-dynamic powertrain applications where vibrations can cause damage, D-Seals can extend the time to service intervals of the engine, contributing to lower emissions through improved efficiency.

 

Developed as an alternative to O-Rings, X-Rings, Square-Rings, and other oval-shaped seals, Trelleborg Sealing Solutions has developed two main designs of the D-Seal, an enhanced double D-shaped seal, and an updated single D-shaped seal. The robust designs each have a customized profile that effectively absorbs vibrations and maintains strength and rigidity.

"The key applications for D-Seals are in engines and transmissions, unlike with O-Rings and traditional static seals, in addition to sealing, the D-Seal provides vibration damping to prevent damage, making it more effective," Peter Astrom, Product Manager, Trelleborg Sealing Solutions, introduced. “The enhanced design of D-Seals optimizes a vehicle’s powertrain efficiency and contributes to a reduction in CO2 emissions."

 

Unlike O-Rings, D-Seals are simple to install and do not twist in the groove during installation, making them suitable for use in automated manufacturing processes. The design has no mold or parting line on the sealing surface, removing the risk of failure at the join or a potential leak path.

 

Trelleborg’s double D-shaped design includes sharper edges that ensure a tight seal fit, for example, against a cylinder lining, evenly distributing pressure to improve seal performance and eliminate the risk of leakage or cavitation damage, where water vapor bubbles form and damage metallic components. 

 

Available in a wide choice of industry-approved materials, D-Seals can be manufactured to provide specific characteristics including temperature, pressure, or media resistance, and colored to aid in identification or camera detection to support automated processes.

 

Additional assembly coatings can also be added to D-Seals to reduce assembly forces and eliminate lubrication during installation.
