Zodiac G58 O-ring Kit Polaris Backup Valve

Product Description

The ZODIAC G58 is a replacement O-ring kit designed specifically for the backup valve assembly used in Polaris automatic pool cleaners. The kit provides the sealing components needed to restore proper valve function and prevent water bypass that reduces cleaning performance. Made from rubber, these O-rings are engineered to withstand continuous pool water exposure, including contact with chlorine and other common sanitizers. Pool service technicians and experienced pool owners install this kit as part of routine backup valve maintenance or when a cleaner shows reduced drive or erratic movement.

This O-ring kit applies to Polaris pressure-side automatic pool cleaners that use a backup valve assembly. Compatible models include the Polaris 180, 280, 360, 380, and 3900 series cleaners. The backup valve is a critical component that intermittently reverses the cleaner to prevent it from getting stuck, and worn or cracked O-rings in this assembly are a common cause of valve failure. Replacing the O-rings restores the seal and proper cycling of the valve.

Key Features

• Rubber construction rated for continuous pool water and chemical exposure
• OEM-style replacement seals for backup valve assembly
• Addresses common failure point in pressure-side cleaner drive systems
• Fits multiple Polaris cleaner models with a single kit

Compatibility

Designed for use with the backup valve assembly on Polaris 180, 280, 360, 380, and 3900 series automatic pool cleaners.

Installation Notes

Installation is performed by pool service technicians or qualified pool equipment servicers. Before servicing the backup valve, shut off the pool pump and relieve any pressure in the cleaner line. Lubricate new O-rings with a silicone-based pool equipment lubricant before installation to ensure proper seating and to extend seal life. Do not use petroleum-based lubricants, as they degrade rubber O-rings.
