The O-rings and diaphragm seal within your vehicles EAS valve block system can wear causing the symptoms noted above.

The O rings and or diaphragm wearing can lead to the compressor overworking and can cause complete EAS falure, we always recommend replacing the diaphragm seal when replacing the o-rings in the valve block as both can cause leaks and EAS failure.

Fit our improved material O-rings and diaphragm seal and restore your EAS system to full health.

Fit our Viton O-rings and cure those leaks, importantly our O-rings are made from Viton 75, this material is suitable for the elevated and varing temperature range which the valve block endures. Viton rubber also has extremely good wear resistance far outlasting Silicone and Buna O-rings. Beware of cheap kits with Silicone and Buna O-rings we only ever use Viton.
