Onga Pantera PCF II / Davey / Monarch P4 / Hurlcon QX Cartridge Filter Lid - 93515

Cartridge filter lid fits perfectly but associated O ring was slightly small which allowed small leak from around lid seal. used petroleum great on seal but did not stop the leak. reused old O ring and fixed the problem.

It’s got a leak somewhere that I am having trouble stopping. I’ve tried a new seal and repositioning it.

Exact fit anddelivery time was great.
