How exactly does one remove the baffle assembly from the lower filter housing? It looks like you need a special tool to insert into the fitting from the outside??IMG_0883.jpegIMG_0884.jpeg
 
The outside has an extension that threads into the inside. Hold the baffle inside and use a rubber strap wrench (or another mechanism to not damage the outside threads) to unscrew the outside.

Thanks! I finally carefully grabbed the bulkhead fitting from the outside. There is only about 1/2” wide area to grab, but I was able to get it with a filter wrench.
New problem….the new o rings for the bulkhead fittings don’t seem like the correct ones. I believe the o ring is Pentair PN 86006900. The supply store gave me a non Pentair part and said it was the same o ring. I don’t think it is. New on the left, old on the right.IMG_0894.jpeg

My filter was mfg in 2016. According to the footnotes, I’m using the correct part 86006900. However, it’s not the Pentair version…it’s supposedly compatible. It doesn’t fill the o ring groove in the bulkhead fitting like the original. It’s clearly not the same size.
