  • I think we may both be mistaken. The threads do not seem to line up well with my 18 or 20 TPI gauges. Checking the manufacturer’s web site suggests that they are using the British Standard Pipe system. That would make these fittings BSPT R-¼, that is a tapered ¼" pipe fitting with 19 TPI.

  • The ones I received are definitely ¼" NPT. Try a ¼" fip (female iron pipe) fitting - It is a perfect fit. In fact, I used brass ½" mip - ¼" fip couplers (bushings) to make a base. The ½" male end can be screwed directly into a ¾" hole in hardwood. Nylon bushings are cheaper but harder to find.

No public wish lists :(
