Alt Static Air Source Options

[lr172]

Had leaks on my previously leak free static system last week. Finally tracked it down to the air switch I put on the panel. It came from Mcmaster, which generally is mid range quality. Seems the orings shrunk over the last few years. Am a bit hesitant to just replace it, but have a 1/2" hole in my panel for it. Any suggestions for a better quality switch or ideas for a better solution? On my 6, I just used a TEE and a cap, but was easy to hide it from view. On the 10, none of the tubing is exposed to the pilot. I was considering a bulkhead fitting with a cap, but is kind of ugly.

Appreciate any ideas

Pneumatic toggle actuated valve for alternate static air source. You will also need our P-515 fitting to connect to 1/4″ tubing.

Thanks. That looks identical to the one that just failed. Looks like the sam mfr stamping.

Mine has been leak free for over 550 hours. Sorry yours failed.

Well now I know where to look first if I develop a static leak. I have the same toggle valve installed. I imagine something like that is difficult to make to where it wouldn't be susceptible to o-ring shrinkage. A bulkhead fitting with a cap is an elegant solution as long as it can be tight enough to seal well and still be loosened by hand when you need it.

Basically the same switch I have in the SubSonex as a gear switch (pneumatic gear) - hasn’t leaked in six years… but then again, I have a dual air pump to keep pressure up if it leaks! Not like a static system that needs to be very leak free….
