Received as advertised Works well

Perfect replacement

Part of a chemical feed pump

The Stenner Pump Company manufactures peristaltic metering pumps which produce high pressures for injection, but with a slower rise time than piston or diaphragm type injector pumps. I'm using this injection module with a Uni-dose pump. So far, so good, but I'm wondering for how long? Please skip the part about contacting the manufacturer. Stenner will correctly point out that their valve is designed to be used with their pumps, but that does not necessarily mean it won't work in other applications. Their duck-bill style check valve costs 80% less than the Uni-Dose ball-check comparable model, so it is worth a try, at least.

Nothing can pass thru check valve in either direction.

First off I would like to clear up some reviews,1 the 1/4 inch is for 1/4 inch tubing and the 3/8 is for you guessed it 3/8 tubing. 2.It has 2 sizes for screwing into what size T you are using from 1/4 or 1/2 .The ferrel is inside the nut you just slide the tubing inside the nut and push onto the threads then screw onto the threads by hand no tools needed . Make sure you use thread tape so you do not have to over tighten when installing into your T. This product is hands down the best one on the market. Cleaning is easy ,I put a valve on each side before an after T so I just turn them off and remove whole valve use a brush internally, rinse and replace.

Part arrived on time , price was good

Look at the review regarding pipe diameters....the lady was right, you need to watch your diameter. The product is excellent.
