X8R Ltd is a British company completely dedicated to providing high quality improved design vehicle components; correcting original manufacturers design faults. We take the common faults associated with a variety of vehicle manufacturer’s parts and re-design and manufacture parts that will not fail again or that will prevent damage to vehicles.
Leak from EAS system but no visible leaks when testing components, vehicle on bump stops? Slow leak? Complete failure of EAS system?


The diaphragm and or O-rings within the valve block can wear and can lead to the compressor overworking causing complete EAS failure, 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 Viton O-rings and cure those valve block leaks, importantly our O-rings are made from Viton 75, this material is suitable for the elevated and varying 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.
Fit our diaphragm seal, this is made in the same way as the OEM seal, beware of aftermarket designs that cause the compressor to run on and burn out, this part is precision made to prevent this.

1x complete Valveblock o-ring overhaul kit consisting of:
1x Diaphragm Solenoid Housing Base Seal
3x Valve Seals
18x Diaphragm Solenoid Base Seals
7x Solenoid Plunger Seals
4x Port Seals
