Does stored Mastercool oil deteriorate over time?

Maccer on Tue July 28, 2009 7:37 AM User is offline

Year: 1965
Make: Ford
Model: Mustang
Engine Size: 200ci
Refrigerant Type: 134A
Country of Origin: United States

Actually... I've got two questions --

1)
I bought a mastercool vacuum pump about 2-3 years ago along with the oil, which I still have stored. Still good? I know some products like brake fluid need to be tossed out after time if the seal is broken.

2)
Have a new sanden compressor/evap/condenser/drier/hoses/accum valve and will be installing the new A/C in the '65 mustang as time permits over the next few days. The sanden compressor came with an assortment of differerent sized green O-rings. Those arent to be used on fittings to the conderser, evaporator, are they? Im guessing "those" connections should be made up without O-rings... correct?

The O-rings are probably a kit. It may contain all the "universal" o-rings for the systems. All the hose connections should have an o-ring. Check the face of the manifold-to-compressor block. It too should be grooved for o-rings.

Just able to get back to the computer Ken. Phoned the folks at Classic Air and they told me the o-rings are for compressor-to-hose fittings only . The other connections are flare and not made for the o-rings.
