Keep your pressure washer sealed tight with this full 20-piece OEM O-ring kit from Annovi Reverberi.

This kit includes 20 genuine O-rings designed to match the factory spec used across Annovi Reverberi pressure washer systems. Whether you’re tackling a full rebuild or just stocking up on spares, this set gives you the right parts to fix common leak points on hoses, guns, fittings and internal pump connections.

All rings are pressure-rated and built to handle heat, wear, and repeated use - making them ideal for preventative maintenance or restoring proper sealing after a tear-down. It’s a small investment to avoid big problems later.

Perfect for owners of AR591+, AR680, AR630+ and other compatible AR units.
