aerospace Pressure Switches

01/16/2008 11:25 PM

Is there a standard metric thread used for the pressure port of aerospace pressure switches? Is this a recognised BS Standard, If not what is the most common sizes used.

Designing a pressure switch with a MS33656E4 port just wanted to review an option with a metric equivalent

If I sign in can you answer me - whats the big secret thought this was the whole point of a forum

If the pressure switch is for hydraulic and into a manifold, it would be best to go with either 1/8th BSP or 1/4 BSP (1/4 BSP being the most common).

If it is going into pipe work (hydraulic) you could go either BSP, JIC or metric.

If it is going into fuel pipe work (deformed ends), such as on Jet engine or rail vehicle it would probably be better to go with JIC.

Yes, you can go with metric in any of the above systems but they are less common (until people get converted over, and the sooner the better).

If your pressure switch is for gas or any other consideration, seek advice elsewhere or provide more info'!

PLEASE NOTE:- the number of IF'S in this post! Specific questions beget specific answers!
