Stainless Steel EGT 1/8″ NPT Compression Fitting
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.
