This single O-ring replacement is a small but essential fix for keeping your AR pressure washer running right.

Designed to match OEM specs, this replacement O-ring is made for sealing connections across the Annovi Reverberi pressure washer range. Whether it’s a worn-out gun fitting or a hose connection starting to drip, this is the go-to part that keeps things tight and leak-free.

It’s pressure-rated, heat-resistant, and sized for M22 fittings - giving you a reliable seal that can handle the water flow and PSI your machine puts out. A quick, low-cost fix to restore performance and stop unnecessary pressure loss.

Compatible with AR models like the AR591+, AR680, AR630+ and more.

• Built for Pressure Washers: Handles high pressure, water temp, and daily use.
• Stop Leaks: Prevents pressure loss from worn or cracked rings.
• Sold Individually: One ring per pack — keep a few spares on hand for maintenance.
