## Description

desertcart.com: Milton S-684 1/8" NPT Tank Valve - Pack of 2 : Milton: Everything Else

Review: Great for DIY pressurized containers - These valves came in a two pack. They are good quality and the threading is slightly thicker as it threads in. This was perfect because I used it to be able to pressurize a scepter water can. I would recommend these to anyone!
Review: leak free, brass, 1/8npt pipe thread - Way cheaper than I could buy vocally. Common 1/8"-27 thread tap. I used 11/32 bit before tap, worked fine. Holding 150psi air pressure with 250° temps.

## Features

- 1/8" male national pipe thread
- Maximum pressure of 200 pounds per square inch
- 1" overall length

## Questions & Answers

**Q: Does anyone know the thread size for the male end which would go into the object you are attaching the valve to?**
A: 1/8 national pipe thread

**Q: Will it burst at 200 psi?  what does it mean.  e.g. some tubes  say 150 psi max working pressure... and burst pressure is 500 psi?**
A: That is a 200 PSIG working pressure... theoretical burst is usually 4-5 times the working pressure.

**Q: Do you need some type of washer or rubber seal to be sure there is no air leak?**
A: These screw into a 1/8" FPT fitting of some sort.  You will need some thread sealant, but no washer or rubber seal.

**Q: Buying in 2016 here, and pic says 2 valves whereas listing says one. Is it 2 valves or not? Reviews differ.**
A: One

Put one on my fuel regulator on my f-250 7.3 and it's all good. Not much else to say other than it works.
