2 PCS Brass Bulkhead Fitting Coupling Both End 1/4" NPT Female

Worked great worth the money

Perfect for solid mounting an air chuck in my engine bay for onboard air. No leaks.

Item as described and shipped as stated

Didn't know if these would work, but they work like a charm. Good quality and a value for the money. Would buy again if needed in the future.

Good price, but the silicone gaskets are too soft and squeeze out from between nut and the bulkhead. Would be better if the gasket were a different more stiff material and the nut more like a flange nut. Overall it did work for my application but I had to make new gaskets out of cork rubber and even those started to squeeze out a bit, really need that flange, the contact area of the nut provided just isn't enough

These are quality, well made Inexpensive and good looking, fit is good just beware of sharp corners. RECCOMENDED

They work very well, but the washers they come with are crap. They cut and shred before you even get the brass pieces remotely tight. I switched them out with some different rubber ones I had and they worked great. I used them to make 3 seperate connections through my truck bed for an on board air compressor system. Once evey thing was installed and under pressure I tested them for leaks with a lil soapy water. Not a bubble to be seen, so mission accomplished.

Had an oil leak in my snowmobile oil tank. ordered these bulkhead couplings and used one in the tank to get rid of the grommet from the factory. No more oil leak even to this day. I have a spare if my other sled starts to leak. Great product for the money.

Very well made threads are cut perfectly. Sealing gaskets work well.

Very well made and sealed perfectly.

Perfect for what I needed. Took awhile to find a bulk head that is npt on both sides.

I chose this fitting to fit a .8" diameter hole, as it's listed 3/4" -16 external thread, which is a standard fine thread. However, it's actually a bastard thread. Actual diameter is .82" and the TPI is 14. This won't fit my bulkhead. Also, the plastic washers are .69" internal, which means they don't come close to fitting over the thread. At least the NPT threads are good.
