(Sebastien) ________________________________ Message 1 _____________________________________ Time: 07:48:14 PM PST US Subject: AeroElectric-List: Re: Plumbing Instruments From: "rparigoris" Hi Group After a nice job of plumbing I tried a leak test pulling altimeter to 1,000 from Zero. Leaks about 108 feet per minute. Shoot. Every one of my nothing installed Nylon fittings were leaking. A day job to pull them out (all barb fittings, tubing would need replacing). I tried some thin no stink silicone #3140 while pulling a 1,500 foot vacuum. Worked great. After 5 minutes I dropped pressure to 1,000 for half an hour, then let it go static and cure overnight. The fittings are from McMaster Carr and don't have a seam I can see from molding. I tightened them smartly. Ron P.

From: "rparigoris" Hi Group After fixing vacuum leak on static system, I set altimeter to zero and pulled a 1,000 foot vacuum. My Winter W-6423 in 3 1/8" airspeed indicator is showing 151 knots. I kinda thought it should be indicating 135 knots? Is this acceptable? If not what should I do? Thx. Ron P.
