What diameter EGT probes does this work with?

  • It will hold a 3/16″ diameter probe.

What size drill should I use?

  • Use a “Q” letter size drill or 0.332″ for best results. A 21/64″ drill bit will work if you only have fractional sizes. If you happen to have metric drill bits, this is very close to a 8.5 mm drill.

What do I do if I need to remove the probes? Your notes on EGT port caps indicate they don’t work with these fittings.

  • Unscrew the bung and cap the hole with a standard 1/8″ NPT pipe plug.
