Good quality

I bought this for my brake booster on my Chevelle and I love these little things, be sure you want it in the hose though, it's a pain in the ass to take out and turn around when you get it backwards like I totally didn't.

Used for condensate pumps in basement

Installed in-line from each condensate pump to stop them from pumping water back and forth into each other across the main drain they are attached to.

These worked perfectly for a long time under harsh conditions.

I am used these a check valves on a system that runs mineral oil at 140 deg. F 24/7 for 16 months with no problem at all. It was time to replace the motors and tubing just as routine maintenance and these were still working fine. As I took the hardened tubing off of one of them the valve cracked, but that was fully expected because mineral oil makes plastic brittle over time. IN A NUTSHELL: These worked perfectly for a long time under harsh conditions.

3/8 check valves

I only needed one, easy to install and fit correctly in 3/8 hose. Not much else to say, 1 way check valves.

Great for Condensate Lines

Wanted to tap a second condensate pump into the drain line for an existing pump instead of running a whole new line to the outside. A couple of these one way check valves, along with a brass T fitting and a small length of vinyl tubing, and voila, works like a charm. These have been installed for six weeks and they are functioning perfectly.

Valve works good

Update: 03/11/2019 Lucy from BBT team has resolved my issue. You will have an exceptional customer service if you have any issues with this product.. As I mentioned earlier, other than the missing item, this product works as expected without any issues. This item works as expected.. but the item description says 2 pack but have only recieved one in the package. I was in need of two.. And now i have to order another and wait for few more days to complete my project.

Works great!

Function great with clean liquid. Any liquid with debris the internal valve could get wedged stuck and not check.

Perfect for aquaponics Air pump.

Using this on a large hydroponic air pump: Hydrofarm Active Aqua AAPA110L and has a 3/8” outlet. It’s rated at 110 liters per min. Seems to be doing great!

Needed this as a water check valve

I used these to connect a dehumidifier pump to the drainage line for my air conditioner. They work fine and water from one pump doesn’t flow into the other.

Compact and works

Use as a secondary check valve to keep two long condensate pump lines primed. Worked perfectly with the low psi of the pumps.
