vacum setup

I'd thought of thought too, but when I bought one from HD, the pipe threads just didn't seem right..Chink made of course.

Just didn't want to take a chance on cross threading the pumpm intake.

Some take NPT and others take MPT. So you have to be care ful on what you buy.

I got my one of my tees from Fastenal and it cost 2.99.

I talked to a local vac pump servicer and got my sizes straight before I took the plunge. You cross thread the the in take you are in for some expensive OEM parts

And from the replies you may find that there are things that you may want to add and others that you'll remove.

Way to XL.

You very may well consider adding:

Nylog

Small bottle of denatured alcohol to clean sensor

Ya i order the nylog and keep the alcohol in the truck i clean the sensor every couple of uses

I ran the fitting in with some sealant on the threads.

good point. I didn't mention i have a bottle of 91% isopropyl
alcohol ( common rubbing alcohol ) that I use to clean my sensor in my all three of my micron gauges.

Most instructions indicate 70% alcohol...dont use it. The remaining 30% is water.

If you dont blow out your micron gauge with dry nitro, compressed air or Bone Dry co2, you rust the sensor with the higher water content on the cheap 70% alcohol.

FWI for those who aren't in the know: 91% isopropyl is available super cheap at most drug stores.

To clean your micron gauge use an eye dropper and fill the inlet about 2/3 or 7/8 full.

Place thumb over inlet opening and shake vigorously and then drain alcohol.

Repeat three or four times and blow out in the aforementioned manner.

Or you can allow the gauge to air dry for two hours. If you insist on using 70% Isopropyl then a dry gas purge is mandatory.

This may be common knowledge to some or most but it is worth mentioning.

In my case I got the tee that had OEM specs. My pump guy said on to use OEM O rings(no sealant) which he sent me gratis.

Like I said, check your OEM specs first! I have a Robinair 15600 6 CFM. Other mfg are different.


Got one small prob..my pump oil is migrating in to my 1/2" evac hoses...got a bad check valve.

It's isopropyl that i use that what fieldpiece said to use to clean it

On the topic of moisture content of alcohol....

After cleaning the micron sensor, wouldn't it be wise to install it on your vacuum pump and run the pump?

Would seem to me to be a quick and effective way to dry the sensor out.

Of course, you run the risk of contaminating it with oil right after you cleaned it...


Hmmm.

Thoughts?

[timetable15]

From the instructions on fieldpiece gauge after cleaning it let it air dry
i add the alcohol let it sit and turn it upside down give it a little shake and put it in the sun to dry it out

[timetable15]

Drop isopropyl (rubbing) alcohol into the opening of the SVG2 sensor and pour it out. Leave the sensor opening uncovered long enough to completely evaporate all of the residual alcohol. Do not use an object such as a cotton swab to clean the sensor, you may cause damage to the sensor.

Question last time i used my pump i had a little bit of oil coming out of the exhaust
is that the check valve going bad

Mine does too a little at the beginning of an evacuation when the airflow is highest.

Is the oil level a bit too high?
