Not quite sure if is a half inch. I measured on wp500 bleed male, and I've got ~11mm. But I'm quite sure that is not metric is most likely imperial. Friend Google say a match of 7/16" at ~11mm but I don't know... Keep looking.
Thank you!
Well, not find so far what type of nut is that one. Nothing seems to match. 1/8" BSPP male is only 8.7 mm inside. 1/4" BSPP male is 11.6 mm inside. FOSTER 2202 Quickplug and 22-2 adapter is (1/8" NPT) - 10 mm - not match with what I need.
The bleed brass adapter screwed in WPX is 10mm inside (1/8" MPT) and 11 mm outside and don`t know what type is.
Really sorry for the delay as I have been travelling.
Please always feel free to email support@picotech.com for anything requiring an answer.
Anyway, the details are:
The Thread size for the ¼” OD compression is 7/16" X 24
The brass fitting is a part of the Watts A-22 (LFA-22) Compression fittings, complete with an “Ander-Lign” tube to male pipe connector with brass insert. The O.D. threaded piece is 1⁄4" OD Comp. X 1⁄8" MIP
