Onga Pantera PCF II Cartridge Lid O-Ring (OR020 / OR534)

Bought the O Ring to replace the original O Ring that was installed in 2012. No one had one in stock in the Newcastle region so found it on line and bought it from Allstar Pool Parts. I spoke to them by phone and then ordered it. The item arrived a few days later, the price was excellent and it fitted perfectly. Well done Allstar Pool Parts

It appears to be too soft or slightly smaller than the OEM product. After about about 10mins, the seal started leaking from around the join between the new lid and the cartridge cylinder. I placed the old seal back on the new lid and there were no leaks thus the assumption of the seal being fractionally small or too soft.

I received my filter lid in a short time and it fitted perfectly
