3/8" 10mm Inline vacuum Barbed Check Valve,1Pcs/ 2Pcs /5Pcs ABS One Way Water Non-Return Breather Check Valve for Fuel Gas Liquid Air

I used this item to repair my older Cuisinart 12 cup coffee maker. The original check valve which was imbedded in the input water tube had disintegrated and was not available as a replacement part from Cuisinart. I cut out the old valve from the rubber water line tubing and inserted this check valve in its place. The 3/8" nipples fit perfectly into the tubing and sealed well using some small zip ties to tighten. The coffee maker is now working perfectly again.

I bought these to install on a dehumidifier condensate line that I had run through a wall to discharge outside of my house. The line was holding water after the pump would stop and I was worried that that line would build up scum or have problems during the colder part of the year. My thinking was this would allow for the entrance of air into the line and breaking the surface tension of the water and allow the line to drain by gravity. This worked exceptionally well for my purpose and fit very easy to install into the 3/8" tubing I had been using. They appear well designed when I checked them in both directions by air pressure.

VERY low valve open pressure- perfect for something like a small condensate pump. I recently ran my condensate to a sink drain pipe and wanted some reassurance that if the pipes ever clog I won't have anything flowing back down to my pump.

So the most important thing for me is they would work even in super light water flow, and they do. That is great. Issue was consistency. One of them started malfunctioning and letting some water through, after a little use. This was actually adequate for my use, but annoying. So you can swap it out for another one, or string a couple in series to solve that issue. Overall not a bad check value for low pressure purposes.

The perfect fix for my chilisleep dock pro the check valve under the reservoir went bad and would drian it when turned off

Item recieved is what is shown and described. Worked as a valve and doesn't seem to be restrictive. Fluid flows very well one way.

Used this as a vacuum booster check valve and a pre catch can PCV valve in a turbo application. They have been in use for a solid month now and seem to hold up well to engine bay temperatures, crank case vapers, and about a 40lb pressure differential across the check valve.

I installed these in the line down stream of the condensate pump for my A/C unit. The first one lasted a couple of years. I noticed the pump cycling more than normal and checked it. the valve was letting water backflow. I installed the second valve ,and it failed within a week. The pump is only pumping up about 3 feet and thru about twenty five foot of line. The check valve should be able to hold against that small amount of back pressure.

replacement for condensate pump check valve. works great.

Perfectly working product for the scope, and delivered on time.

Good checkvalves. I only needed one, but it works good as an extra to my my furnace water condensator. I'll likely add one or two to my ATV vent lines as well.
