• Fits Pentair FullFlow sand and D.E. valve models 263010 and 263011.

Description

The Pentair 275300Z O-ring is the correct #2-154 Buna-N 70 replacement seal for Pentair FullFlow sand and D.E. valve models 263010 and 263011. Pentair lists two required in the valve assembly, so replacing both during service is the clean move. This is not a universal O-ring. Match the valve model before ordering to avoid leaks, poor fit, or repeat teardown.

Pro Tip

If the valve is already apart, replace both required O-rings and inspect the valve adapter seals at the same time. Reusing old seals is usually not worth the risk.

Installation Tips

Shut the pump off and relieve all system pressure before valve service. Confirm the valve model is 263010 or 263011, remove old seals carefully, clean the grooves, and lubricate replacement O-rings with pool-safe silicone lubricant only.
