Environmental Excellence

Fugitive Emission Control

We have wide ranges of fluid sealing products that are proven to reduce VOC fugitive emissions from pipelines, processing plant and pressure vessels.

Many of these products are TA-Luft certified to demonstrate Best Available Technique under the European Union's IPPC directive.

In addition, our world-leading range of rapid gas decompression (RGD) resistant elastomers and seals help reduce the potential severity of leakages at oil and gas wellheads and pipelines.


DuPont™ KVSP®
