40Pcs Plastic Quick Fitting 1/4 Inch Pneumatic Push Connector Pipe Tube Fitting Straight, Elbow Union, Y Union, Tee Union Connectors PU6,PV6,PE6,PY6 Parts for Air Hose

They did the job for my pneumatic tire machine.

Worked great for water lines no leaks in any fittings. Used for mistking without any modifications.

I gave it 2 stars for the price. 1/4" tube barely fits in them. You really have to force it in. You'll never get the tube back out though.UPDATE: I just dug these out again, they DEFINITELY do not work with standard 1/4" tubing. I have a feeling they are meant to work with metric tubing. I have some flexible tubing that measures 6.25mm which works ok but is still extremely difficult to get back out. The 1/4" rigid nylon tubing that I use in my shop measures 6.39mm and definitely does not work with these fittings. Waste of $. I should have returned them.

They worked good

These devices leak. Will not seal. After doing an installation I performed a vacuum leak test to 10 inches wc. Could not pull any vacuum. Pressure test revealed all couplings leaking. Not a product I will ever purchase again. Waste of money! NO STARS HERE

Many leaked and not good. Would not buy again!

Item arrived on time (actually before the quoted date), and everything was received as advertised. I have not actually tested the fittings in a long term reliability test with my air setup, but they are the correct dimensions I ordered and when test-fitting a 6mm (1/4in od) hose, they fit snugly.

False advertising, don't properly fit 1/4air line.

Size was incorrect , it was all 6/mm

bien

Products meet my expectations!
