need help quick trouble with pyro compression fitting
I was installing my gauges and seem to have lost the part of the compression fitting that gets sandwiched.The sleeve part that goes on the inside.I have looked this evening at my local parts stores and home depot,lowes,but can only find them in brass.Will this hold up to the heat?My only 2 other options as I see it are to make a steel one from a steel spacer by drilling it out and cutting it to length.Or putting a steel pipe plug,that I have yet been able to find,in it until I can get one ordered on line.
I already have the hole drilled in the manifold so I have to do something to be able to drive it.Any suggestion?Will the brass stand enough heat?

Is it a clamp type or drill & tap type sensor? Mine simply had an adapter screwed into the tapped hole, then the sensor itself screwed into the adapter. No spacer or anything involved. Here's what it looks like:

He's talking about the thermocouple that seals the probe. a brass one will work fine. the melting point for brass is ~1700 and its fracture state (bendable) is ~1200. It will be fine as long as you don't run 1200+ for extended periods, but if you do, it wouldn't be the pyro i would worry about.

It is the drill and tap.Inside that adapter is a ferrel ,not sure if that is spelled right,that gets sqashed to hold the adjustable probe tight.Go to this page and look at r683

I do and I know what he is talking about, the brass one should be fine since it is isolated(on the outside) of the manifold. It is a Ferrule that is under the nut that IZZY shows in his picture. It is used to adjust the depth of the probe in the exhaust stream.

Ok I can tell you that it does take a ferrul and one from lowes works fine.They were not quite long enough so I used 2.I just went in there with my thermocouple and probe and check them till I found one what fit.
I got all the gauges in and love them.trans. temp never really moved until I let it set and idle awhile then it came up to 190 and stayed there,it was above 90 here today and this was after towing a trailer with a car on it for about 25 miles.The pyro moves alot faster than I had expected but I couldnt make it get over 1150 even on 120hp with my foot in it,thats a good thing.With the car behind me and dp in 80 econo,cruise at 75 with 410 gears it road at 750 which was good I thought.My buddy and I got the most enjoyment out of the boost gauge tho.You could watch it and tell when the motor used more and less.On the highway with the cruise on it would stay steady on flat stuff.Then going up overpasses it would come up going up ,going down it would go down to zero.Then level back off.I dont know why but that was really neat.
Thanks to everyone who responded.Thats what I love about this site.

I probably have what you were talking about on my thermocouple but was not really sure what you were talking about. Mine came assembled and I just installed it a long time ago. Glad you got it.
