FlyingDude Posted January 22, 2025 Report Posted January 22, 2025 Guys, Ssp-885-2 requires the use of POB or equivalent gasket sealant on the Donaldson oil filter adapter gasket. I can't find POB on aviation sources. People mention POB ( Perfect Seal #4 for that matter) on marine sites but boats are for rich people. I'm a cheap mooney driver. What can I use? Thanks.
