Swapping out the upper cylinder on my Kioti DK6010SE. Curious if those hydraulic hoses sealant or not.

Huh?

Only pipe fittings need sealant. Most others use gaskets or metal to metal.

The only fitting needing sealing is where it adapts to the cylinder itself. Silver goes into orange via pipe thread.

NPT(pipe thread)needs sealant(not teflon tape),tapered threads do not(metal to metal).

I don't remember the name of it but when I did some fitting replacement the thread sealant was listed for hydraulic lines.

I'm not aware of any hydraulic hose fittings that need sealant. I've heard that if you use sealant, you risk it getting into your hydraulic system, and potentially causing issues.

Tapered threads need something, tapered seat fittings (SAE/JIC) do not need sealant, and if there's O rings then those do not need sealant either.
On tapered threads tape is fine if used CORRECTLY which most people don't do, the tape should start one thread back so none get into the medium inside... Thread sealant is a lubricant and a sealant so it covers both but some people use tape and sealant...

Only tapered threads (NPT) need sealants.... Tape or paste or fluid (locktite?) .. Straight threads do not "seal" they provide pressure to make a metal to metal contact seal (like JIC connection) or use some sort of gasket ("O" Ring?) to make seal..
