Quick disconnect replacement 1640 loader

[CJN8]

Replacing the QDs on my 1640 loader as they are leaking and new o-rings did not help. The hoses are 3/8 npt, what should I look for in a replacement? What ISO series, just the standard agricultural type? On the threads I assume Teflon tape is a no no, just use paste, or? Thanks for the help!

Most likely they are ISO 5675 "AG" type. Tape is a no-no as you guessed, any PTFE-based paste is good, as are some Lockite and 3M products but they are very expensive.

I have had good luck with 'Leak Lock' to seal those stubborn hydraulic connections.

Anothe item is "aviation gasket sealer", its available at Auto Zone or Advanced Auto. Brush the threads and let tack dry for an hour or two.

If you want to replace the couplers with a "better" upgrade go with flat face connectors. When they are disconnected they stay clean unlike the AG connectors.

Thanks guys, all really good info. Wolfman are the flush style connectors less likely to leak?

Yes a lot less leakage issues because they stay cleaner.

Here is a link for them for a relatively cheap price,
