NEVERLUBE DIVERTER KIT
Product Overview
The standard specification for restoring internal seal integrity in Jandy 2-port and 3-port NeverLube valves.
The Jandy 4720 Diverter Kit is a proven choice for repairing valves that suffer from internal bypass or stem leaks. This OEM assembly includes the diverter, shaft O-rings, and the lid O-ring, ensuring a complete seal without the need for constant maintenance. In our experience, using genuine Jandy parts prevents the common sizing issues found with generic alternatives that often lead to stiff handle operation or premature seal failure.
Benefits & What Makes It Different

Lubrication-Free Design
Constructed from proprietary materials that do not require silicone grease, preventing debris buildup inside the valve body over time.
OEM Precision Fit
Specifically engineered for Jandy NeverLube 1.5-inch and 2-inch valve bodies to ensure a 100% shut-off when diverted.
Compatibility

- 1.5-inch x 2-inch and 2-inch x 2.5-inch valve bodies
When To Use This
Pro Tip
When reinstalling the lid screws, always use a hand screwdriver rather than a power drill. Over-tightening can easily crack the plastic valve housing or strip the threads, which would require replacing the entire valve. In regions with high calcium hardness, check the internal housing for scale buildup before installing the new diverter to prevent scoring.
Common Questions & Instructions
How do I know if my Jandy NeverLube diverter needs to be replaced?
You likely need a replacement if water is leaking past a closed port (internal bypass) or if you see water weeping from the handle stem. If the handle becomes physically difficult to turn or feels 'gritty,' the internal diverter or O-rings have likely reached the end of their service life.
Does this kit fit both 2-port and 3-port Jandy valves?
Yes, the 4720 diverter kit is the standard replacement for both 2-port and 3-port NeverLube valves in the 1.5-inch to 2.5-inch size range. It is designed to drop directly into the existing valve body once the eight lid screws are removed.
Do I need to apply pool lube to the O-rings in this kit?
While the 'NeverLube' name implies no maintenance, we recommend a very light film of silicone lubricant on the O-rings during installation to prevent pinching. However, the diverter face itself is designed to operate dry against the valve housing for long-term reliability.
