I have a Top N Tilt kit with 3/8 Ag style quick couplers, my tractor has 1/2" Ag style quick couplers (fyi the hose is 3/8"). Will something like a Parker PTR fitting 1/2 x 3/8 do the trick?

Should work if thread dimensions are correct.... Be sure its steel and not brass though...

Thanks, I'll be replacing 6602-6-6 connectors with 6602-8-10, both of which are NPT. Just to confirm since these are NPT they need to be assembled with some sort of threat sealant (e.g., Loctite or teflon tape)?

Depends on if they are 'dryseal threads' or not. NPT can be either way actually. Check with your supplier to find out.
If you do use sealing tape, be sure not to apply the tape to the threads at the very end or overlap the orifice as the tape will get in the system and possibly ruin the pump.

LocTite 545 is the one for hydraulic NPT threads. Teflon tape and dope just lubricate the threads so you can get them tighter, they don't seal at hydraulic pressures. You may be able to get the fittings tight enough to seal but in m experience it's not easy. The 545 is an actual sealant.

I use Detroit Diesel Anerobic sealant myself but you cannot buy it at a local store. Must come from an authorized DDEC dealer.

Yup, not a fan of Teflon tape for this application, I'll be using Loctite 545.

You can buy DDE products. Readily available for anyone that wants to trade their first born and a gallon of blood. He's not building an engine, just trying to keep fittings from leaking. I use PST and have never had any issues with it.

Fixed it for you and a tube isn't that costly either and a tube will last you a very long time. Just bought a full tube last month and it was 6 bucks retail. Of course you won't find it in a box store or online (well maybe).
Amazing stuff with many uses, not just for thread sealing. You can use it as a gasket maker as well and it's solvent, fuel and diesel resistant.

You can find literally anything online. Including this.

I agree that this is the way to go. Teflon tape works well on softer fittings like brass or if you put a steel fitting in aluminum but steel on steel (especially stainless) needs a sealant. The cheaper China made fittings that I have gotten don't seem to have a good thread form and tend to gall before they seal even though they appear tight. 545 helps in this regard.

I'd go with an anaerobic thread sealant if you can easily get it. An alternative, that I have used when I didn't have the anaerobic sealant is Rectorseal 5, a slow (and soft) setting tread sealant. It requires probably 24 hour or longer cure time before you put hydraulic pressures to it, but for NPT-NPT or NPT-NPTF connections it has worked for me, and it's available in most of the big-box stores. Like any thread sealant, be sure to keep it away from the first couple of threads of the male end of the connection.
