TECHNICAL PRODUCTS King New Water Feeder 400/600 ./ 630 Lid Cover O-ring 01-22-9920, 01-22-9926

Part #01-22-9920 is not the same as part #01-22-9926 as it only resembles part #01-22-9920 in that they are both black and round. The material in part #01-22-9926 is a hard rubber where as part #01-22-9920 is more like a foam rubber that is twice as thick and more flexible than 9926. I rated this only 2 stars because after installing it the pool frog cap leaked more than it did before.

O-ring not the correct size, way too large. Ordered from manufacturer thinking this would insure getting item needed. Well that thinking didn't pan out. Quality is ok, but have no use for this item and not worth taking trouble to return. Guess I'll just go to local pool store to see if I can get what need.

The gasket for the pool frog bac pac goes bad at least once, sometimes twice, per season. This is the right replacement for it.

Fits chlorinator as described and seems to work perfectly.

What more can you say other than it fits and works.

fit perfect
