I am ready to assemble my 10PA17C compressor after cleaning and inspecting, which appears to look very good. ...just a shaft seal was bad.
I have read that the PAG oil does not get along with moist air. So, for reassembley I didn't want to use any other lubricants for the moving parts and o-rings, etc. So, is it safe to use the NYLOG Gasket Thread Sealant and Assembly Lube on all these moving parts (bearings, pistons, shaft, etc) in the compressor (or suggest different and/or additional stuff)? Then I was going to tape off the line connection ports to keep any air or moisture from getting inside until this Spring when I install it.
Any other suggestions are greatly appreciated also. Thanks and Merry Christmas!

Do not use Nylog on internal parts. Thin coat of mineral oil will work for lubrication.
Is it ok to use nylog as assembly lubricant inside the compressor for some items? I read that it is ok from http://www.refrigtech.com/NylogManual.pdf (see below), but you say it shouldn't. So, as you recommended, I went and bought some mineral oil from the pharmacy (I hope that kind is ok).
But I was just wondering for sure if it's ok to use internally because I wanted to see if it's ok to apply to the schrader valves and shaft seal rubber and heard it is good at keeping the rubber from drying up. I guess I'm just curious as to why it can't be used internally since I've never been told why it shouldn't (particularly for pistons, cylinders, bearings, etc). I'm just trying to learn something, and not show contradiction in opinions. Thanks for the help.
Since Nylog is a Refrigeration fluid (oil), all sealed system parts can be pre-lubricated. Typical uses include coating of pistons, cylinders, rods, rings and valves. Refrigerant leakage is greatly reduced when shaft seals are coated with Nylog.
Coated Schrader valve cores do not leak and their depressors remain lubricated.
Pre-lubed solenoids, actuators, unloaders or ball valves are prevented from binding
Wrong mineral oil!
41-50000 Mineral Oil
Nylog is not an lubrication oil for your compressor.
Thanks Tim for the mineral oil correction. I'll get some before my assembly starts.
However, I'm still trying to find out why nylog can't be used as an assembly lube when the bottle states that it is. I showed a link stating that it works great for 'assembly' applications involving cylinders, pistons, seals, etc. and that it's also an a/c oil based material.
I understand that you are saying that this information is wrong, but I guess I'm trying to find out is why? Because if I had not found this site to get help from you (and not listening to the other info I have found and read on nylog), I would be here gooping nylog over everything that had moving parts. I would just like to know educationally and also be able to give a good explanation if I'm ever asked the same.

GASKET and THREAD SEALANT
NYLOG renders a strong, flexible, lubricative glaze
that prevents high pressure leakage through
refrigeration gaskets and threaded fittings.
NYLOG never hardens and always
remains temperature and vibration resilient.
NYLOG is fully miscible with all refrigeration fluids
and can be used for high tack lubrication
on internal compressor parts, system valves,
seals and much more.
This is what the manufacture claims, so feel free to use it if you like.
Thanks again. I'll keep it safe with the mineral oil, but wasn't sure if there were any negative effects like clogging, etc. Appreciate your feedback very much.
im about to recondition my AC compressor (nippondenso10PA17C) since it is leaking somewhere in shaft seal.. anyone have manual ??
There are special tools needed for "most" shaft seal replacements, it might pay you to check your compressor on Ackits.com for a "quality reman" or even new. You can e-mail the guys at Ackits.com as they may have "New" offshore replacements for the price of a reman, this way you get one either redone or new and don't need the special tools. If you have never done a compressor rebuild, I would not suggest it..Shaft seals aren't as bad, but still the cost of the tools may not warrant fooling with it..Just my opinion..Hope this helps..
Freedoms just another word for nothing left to lose
