Getting prepared to install new hydraulics to my 4R tractor and wanted to know if any thread sealant is recommended on the fittings shown below or is the o-ring sufficient? There a quite a few of these types of fitting in the 3rd SCV and Power Beyond kits from JD.
I believe they are referred to as SAE Straight Thread O-Ring (O-Ring Boss) SAE J1926-1 ??
If so, would Loctite 565 LOCTITEĀ® 565ā„¢ Thread Sealant Controlled Strength - Henkel or a paste PTFE thread sealant like RectorSeal T Plus 2 https://www.rectorseal.com/rectorseal-t-plus-2/ be acceptable?
