Pelican's AC parts : r134a?

[Bukowski]

Is all the AC hardware listed in the Pelican Parts catalog rated for r134a?

[mattdavis11]

What do you mean by "rated". Will the hbnr orings work with all refrigerants and refrigerant oil? Yes. Does the reman compressor come with pag 46? not sure.

What, specifically, do you have concerns about.

[Bukowski]

Sounds complicated. Thanks.

All the "hard parts" will work with R134. What needs to be changed are the o-rings (to the green ones) and the oil in the compressor to PAG46, IIRC 6-7 oz of it. New receiver dryer ($12 or so here) and you're set.

The color of the o-rings does not always indicate the type of elastomer.
Although some producers color code the o-ring material you can get HNBR
(aka Hydrogenated Nitrile Butadiene Rubber) in green, black or blue.

A simple conversion in terms of oil type is "ester" rather than PAG,
in some cases PAG does not like to mix with R12 mineral oil.

If you are converting then chances you have a leak, hence ... where is the leak?
Most common leaks on the series you have are compressor seals, the compressor to condenser hose and possibly condenser to drier (sometimes on the later). So, fix the leak while you are at it.

What you need to do in basic:
1) Recover whatever remaining refrigerant that is in the system, no pressure in the system.
2) Remove the compressor, turn it upside down and turn the outer clutch hub, trying to push out any remaining refrigerant oil. Inspect the oil for: debris (aluminum particles from a trashing compressor, dark grey matter from worn pistons, and congealed oil). If you have any of those situations you may need to replace the compressor and and liquid ac flush the system. If things look good you can proceed.
3) Replace the drier with a drier having desiccant that is R134a compatible, most today are.
4) Replace all the orings in the system that you can where there joints between components and hoses.
5) Remove the scrhader valve cores and attach R134a fittings that have their own valve cores.
6) Add ester oil
7) Evacuate, charge and test

Absolutely agree with the Ester oil. When I replaced my compressor etc I put in Ester oil and recharged with R12. Now I can easily change to or add R134 if needed. PAG oil reacts with any R12 left in the system/hoses.
