Pneumatic connectors thread

[Vlad]

I am not in the shop right now and would like to order some connectors for pitot-static system. The same ones Doug referred on home page http://www.automationdirect.com/adc/...ght_(Hex_Body)

Could somebody take a look at the thread at the back of altimeter and ASI? Is the thread NPT or other?

Standard pipe thread - NPT.

Thank you guys. Tony an offtop Q for you - in your album image #89 you cut the exhaust pipes at an angle. Is it just for aesthetics or has an aerodynamic benefit?

Hey Vlad! You might take a look at what Stein has. These fittings look really nice.

The pipes are cut short, as I didn't want anything hanging in the airstream. Don't remember where I read it, may have been in Paser's book, but the 30 deg cut is supposed to deflect the exhaust flow down. The deflectors on the bottom of the cowl are there for the same reason, and to gain a bit more clearance.
