Utah Pneumatic 1/4" Bulkhead Fitting, Nickel Plated Brass Push to Connect Air Line Union, Heavy Duty Pneumatic Straight Connector for Air Systems (5 Pack)

Work's like it should, holds tubing perfect.

I used a brake line as the tubing and underneath attached the drip line which is on a timer. It is so awesome and fills up each day on it's own. I have three of these in different flower gardens.

I had an air line that ran through my floor on my peterbilt with a similar bulkhead that was leaking. Found this and it fit great and stopped my air leak. Not really an issue but just watch about how tight you tighten it, I may have stripped one by torqueing it as if it would be holding a wheel in place lol

A bit too small for hydroponics drainage, but it works.

The bulkheads are very well made. But you will have to buy O-rings to prevent any leaking. 1/2" diameter will work and create a tight fit.

I design, build, and sell food processing equipment. I buy a huge variation of pneumatic hardware. I have to say, Utah Pneumatic is some of the best quality I’ve seen... I’m very pleased with my purchase!

now what its advertised as. not 1/8 in pipe thread. its some metric thread important when your counting on this produce to get you moving.

Worked for what i wanted it for. Works great for connecting air hoses to an electrical box.
