5.0 out of 5 starsWorks great! It cuts off the air to the line and Amazon sells them cheaper than can be bought locally.
By Rolla Gravett on December 20, 2014

This brass air cut off switch works great. I use it on my portable air tanks to cut the air to the hoses. With the air cut off to any leaking hose, the pressure will stay at whatever amount of pressure put into the tank. It also makes it easier to take off air nozzles or the air chuck by removing pressure to the chuck or nozzle. With pressure on the chuck, they can be hard to get off and this takes care of that problem. I also checked locally and the price in this area is higher than the ones being sold on Amazon. I like them so much I ordered 4 of them for my air compressors and air tanks.

5.0 out of 5 starsJust the ticket for a quick shut-off on the end of a hose.
By Tech Diego on January 5, 2016
Size: 1/4"Number of Items: 1 Verified Purchase
A very nice SMALL quarter-turn 1/4" valve, priced right.

The scale is hard to take in from the solo picture, but remember that's a 1/4" NPT fitting.
This isn't a full-fist valve, but a two-finger mini valve.

That makes it just perfect to mount straight onto equipment or fittings. I don't feel bad about hanging it straight off a coupler, since it's small and light.

2.0 out of 5 starsUse for gas at your own peril.
By danno11 on April 6, 2015

Valves are far over rated as to their use. Spend the extra 10 bucks and get a valve that won't leak. I can see these working for some applications, however, when you're talking combustibles they are not dependable at all. I stupidly installed two of these on my propane manifold and initially they didn't leak, but when it got really cold, they both leaked enough gas to warm your hands over. I'd say the cost me about 100 bucks worth of propane. I really should have known better and frankly, I do. The price was way too low for a quality valve. I'll throw em in the parts bin. They can be used. Just not for critical applications.

5.0 out of 5 starsand I am very satisfied with it
By Terry Story on October 29, 2015
Size: 1/4"Number of Items: 1 Verified Purchase
My neighbor borrowed my compressor... I always leave the drain valve open when I have finished with the compressor, and when he used it it was open and he used pliers on the old style valve... You know what happened to it, it was toast! I bought this as a replacement drain valve for it, and I am very satisfied with it, although you do need to be sure that you have the room under the tank for it, it does take more space that the old style valves that they come equipped with. Now he will not have to use pliers on the valve and destroy it, he can use his fingers and swing the arm to open(close) the valve! I love it, well made, perfect functionality!

Good valve, not the best description on the item from amazon. please note it is NOT a full port valve and handle has 180 degree swing (closed-open-closed). Otherwise seems well made.

By David Painter on September 15, 2013

I use a couple of these on a vacuum chamber for degassing plastic prior to casting. They work perfectly and do not leak, at all, ever. I am impressed that they work this well considering the price. Great value!

Small with a good seal. I used 2 for drain stops on a marine engine replacing plugs that were really difficult to access in the boat. Now I can reach in with no wrenches and just turn the handle 90 degrees. makes it a much easier job.

5.0 out of 5 starsLight weight and low cost.
By Dan Pomeroy on October 13, 2014
Size: 1/4"Number of Items: 1 Verified Purchase
Only judging by the looks and feel of these valves, they should be perfect for my application. I bought a few Chinese valves from somewhere else in the past and the quality was just to low. These are noticeably higher quality and will be excellent for our product.
The only problem is that I ordered 3 of them and they came in three different packages. I will need to order higher quantities in the future, hopefully I can get many of them in one package.
