Great purchase.
I purchased for my 2006 Workhorse chassis under my Winnebago RV A class. Functions perfectly.

Used this to fix the vents on my 1991 Jeep Cherokee XJ
Finally fixed my a/c vent issue in my 1991 Jeep Cherokee. I tested all my vacuum lines with a vacuum pump and there was no leak, but I was missing the check valve so when the manifold vacuum was reduced under heavy acceleration the air would stop blowing out of the front facing vents and start blowing through the defrost vents. I previously brought a Dorman 47170 which was listed for Chrysler, Dodge, and JEEP and it was defective right out of the box (passed air both directions). I decided to give this a try and glad I did. Was a tight fit on 1/4" hose. Now my forward facing vents continues to work when I'm on the freeway and does not default back to the defrost vents.

Advice for older Dodge pickups.
I have ulterior motives in writing this review, more of advice than a review. The check valve is fine, no problems. Used it on a 1997 Dodge Ram 1500 to correct the vacuum bleed off which effected the climate controls. That's the review. The advice is to locate the initial vacuum port (appears to come from the passenger side of the block) and replace the first check valve on a 90 degree elbow. I wasted a certain amount of time before I discovered where this check valve was located. For what it's worth, I generally work on Chevy's. Needless to say, the plumbing on a Dodge is completely different. If it helps just ONE poor, dumb, SOB... my time has been well spent. The Duck

Nipples are both for 1/4" sized tubing.
Works fine. It is just a simple one way low pressure valve. Replaced a failed Ford piece in our spa that is used to keep primary pump from getting air locked on start up. Wait, I'll get in there right now and test it for ya, aaahhhhhhhh.... yup, it works. One star off for being about twice the price it should be but maybe I'm geezed on todays costs for everything.

Works like a charm, no more gas all over!
Purchased this to replace my failed check valve on my 2001 Kawasaki Ultra 150 jet ski. Woke up to find gas all over the driveway and the side of my ski. Turns out the check valve was no good! Did a quick search found this installed and we have been good ever since. Check valve for a fuel breather tube on Kawasaki ultra jet ski!
