Alan, 

I looked at MIL-I-23594 on the assist site and according to that document,
you want class 2 tape.  The classes are defined as follows:

Class			Backing Thickness (mils)
Class 1		1.5 - 2.5
Class 2		2.6 - 3.5
Class 3		3.6 - 4.5
Class 4		4.6 - 5.5
etc...

You might want to re-check your suppliers.

Subject: [TN] Looking for 3 mil PTFE Tape

Hello Technetters,

I'm looking for Type I, Class 3 (3 mil) PTFE (Teflon Tape) per A-A-59474 
(Mil-I-23594).

I've found a couple suppliers with Class 2 or 4 (2 and 4 mil), but not the 
3 (called out on a drawing; can change drawing to use 2 or 4, but just 
trying to find the 3 mil first).

Thanks in advance,
