Arthur:

Yes...I'm talking about the outer threads; not the depressable valve.

Are there any mass-marketers..ie..Sears, etc. that might sell a tool suitable for this re-dyeing?

I have R-12 gauges, but am simply trying to avoid having to extract refrigerant, remove hose, pay for hose repair, etc.

Thanks.
