Product details

The Jandy R0449100 kit replaces both sealing parts under the strainer lid on PlusHP, MaxHP and WaterFeature pumps: the lid seal gasket, which has a rectangular cross section, and the round o-ring. When a pump starts drawing air at the lid, these two parts are the fix.

Fit

PlusHP PHPF and PHPM, MaxHP MHPM and WaterFeature WFTR series pumps. The o-ring measures roughly 6-3/16 in. outside, 5-13/16 in. inside and 3/16 in. thick. The seal is roughly 6-1/8 in. outside, 5-3/8 in. inside and 3/8 in. front to back. Jandy gives these as approximate figures, so use them to confirm you have the right family of pump rather than as exact machining dimensions.

Symptoms of a worn seal

Bubbles collecting under the clear lid while the pump runs, a pump that takes longer and longer to prime, or a lid you have to crank down harder each season to stop the hiss. Any of those points to the lid seal, and a new seal and o-ring are far cheaper than a lock ring cracked from overtightening.

Installing

Clean the lid groove and the housing face, seat the new seal and o-ring dry or with a light film of silicone based lubricant, and tighten the lid by hand.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pumps use this seal?
Jandy PlusHP (PHPF and PHPM), MaxHP (MHPM) and WaterFeature (WFTR) series pumps.
What is included?
One lid seal gasket with a rectangular cross section and one round o-ring. Replace both together.
How do I know the lid seal is worn?
Air bubbles under the lid while the pump runs, trouble holding prime, or a seal that looks flattened, cracked or swollen. If the lid is tight and the pump still draws air, the seal is the first thing to change.
What are the dimensions?
The o-ring is about 6-3/16 in. OD, 5-13/16 in. ID and 3/16 in. thick. The seal is about 6-1/8 in. OD, 5-3/8 in. ID and 3/8 in. front to back. Jandy lists these as approximate.
