Magnehelic gauge hose configuration

[Scubaroo]

Anyone using a magnehelic guage (I know there's a few people out there with them)?

I bought a surplus gauge, and there were no hookup instructions - I want to connect the mouthpiece from Peter Built to the gauge, but there are three other ports in the gauge - what should be done with them?

Looking at the picture of the gauge at Peter Built, the mouthpiece hose goes into the Low Pressure port on the side of the gauge. That leaves two plugs, and another hose adapter - which holes do the plugs and adapter go into? See the attached picture for the layout of high and low pressure ports on the gauge.

I plugged the HP and LP ports in the back (so I wouldn't lose the plugs) and screwed the brass nipples into the side ports (using the LP port with the Peterbuilt mouthpiece).

I just wasn't sure if leaving the other ports unplugged had any effect on the reading - I'll try that.

you need to plug any low port not in use.

Hi C viper, this is a really old thread with out of date links. Here is one to the mouthpiece adapter.

Not to sound harsh, but have you considered contacting Dwyer and getting your answer right from the manufacturer? Trust me, they don't bite!

He asked that question 8 years ago! Most likely has his answer by now.

Thanks, I did not look at the dates. My bad!
