4PCS 1/4" NPT Tank Valve Anti-Corrosion Brass Schrader Valve with Standard Valve Core with 1/4'' NPT Male,Using with Air Compressor Tanks with Sealing Caps

They work as designed well-made

Solid brass, quality product that works well. A+++++++++++

These brass schrader valve fitting by Breezliy are the perfect solution for many pneumatic project needs. I have some old compressor tanks that I could use these on but for my immediate needs, I had a bad press fit valve on a riding mower wheel that needed to be replaced. By using these in a threaded hole, I was able to install a replacement valve without removing the tire. Fine for a riding mower but probably not for anything out on public roads. The included Teflon tape is handy to have and seals the threads well. If you don't have a female 1/4" NPT fitting for your situation, you can simply pick up a 1/4-18 NPT tap for under $10 along with a 7/16" drill bit to thread your own hole as I did. The brass fitting are machined accurately and screw in perfectly. They perform as expected with my pump and for the current price of $8.98 for 4 (and 2 rolls of tape) I can't fault these so far.

So I wanted air horns on the golf cart. Real ones, not the little compressor driven ones so I needed a tank. I installed a 4.5 gallon tank (actually two tanks that total 4.5 gallons) and put this adapter in one of them. So far I don't need to add a compressor! I just top off the tank to 125psi. The regulator drops the pressure to 75psi for the fire truck horn I have. Plenty of air for a lot of horn blasts since I'm not using the air for anything else. If I opt for air ride suspension in the future I'll need a compressor on board but that seems like a bit much for a golf cart! Actually, fire truck horns are a bit much too I suppose... ;)

I have a 88 Chevy truck on air ride. I was looking to add a fill valve that I can use a regular air chuck for tire in case my compressor failed. I came across these valve and they are perfect, screwed right into my tank, now I have a backup plan for pressurizing the system. Great product and fast shipping too. A+ all the way!

While I have yet to permanently install any of these, I did do a quick pressure test to 50 PSI on all of these and they all held great. No sticking valves, and time will tell how they hold up. Initially, though, these are absolutely worth every penny if you need several schrader valves.

These are absolute trash, only one of the four had correct 1/4 npt threads but the Schrader valve on the other end wasn't standard. The cap wouldn't even screw on it correctly.

This package comes with 4 valve and teflon tape. Fit and finish look decent, and the treading appears good and smooth. Looks like it will be a perfect match for a tire inflation system i'm putting together. Very nice!

Quarter of the price compared to my local option. Arrived fast worked as advertised.

I liked the all metal construction and was perfect for making an adaptor for my air hose when I only need to use my hand pump. The 1/4” NPT directly fits into a female air hose quick disconnect without having to use more adaptors. I used this adaptor with my long coil hose compressed as an air supply for my smoke generator for vacuum leak detection. Useful for those applications that don’t require high-pressure, and not worth the bother or hassle to use your compressor.
