Static port connector on back of altimeter question
 

I've got to change out my altimeter to one with a millibars scale on it. Before I get my gymnasts leotard on and contort myself behind the panel is the little connector that joins the static hose to the static port on the altimeter reusable or do I need to get myself a new one before I start?

Reusable, 1/8" pipe thread into the instrument. However, the can be known to break, so having a spare is a good idea.

You're back :ok: Really hope you are on the mend :D

Thank you sir, and do I use any plumbers tape type stuff or sealant on the threads.

PTFE tape is best avoided on aircraft. If you use too much or wind it in the wrong direction, loose tape can potentially cause a blockage. Maybe that wouldn't be too serious for an altimeter, but it isn't good practice.

A thin bead of thread sealant like loctite 567 applied a couple of threads down from the end of the fitting will give a good seal. And don't overtighten the fitting. Finger tight plus one turn is all that's required
