Our kit includes a new improved design piston seal constructed to the finest of tolerances from improved materials to restore full output. A replacement piston liner to replace your scored or damaged liner. Full filter replacement kit to allow you to replace all filters, the original filters saturate quickly and drastically effect output, our improved replacements will solve this problem. 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 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. 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.
