Used them for drip irrigation. They failed after I use, about 5 minutes of water flowing through them. I’m gonna guess they just can’t handle much pressure. And, if they can’t handle much pressure I have no idea what they’re good for.

They are cheap and look cheap but work great. I tried the first one and I saw air sucked in the line (hand soap). Tried the second one with same result and thought the quality of the seal was bad. Tested both with syringe and water and there was no leak with pressure. Turned out my tube was cracked and sucked in air, not the valves.

I ordered these to replace a true 1/4" valve. The edge of the barbs is barely 1/4", but it basically slips right out of a 1/4" line. You can see from the images the difference in size of this compared to a true 1/4" valve.

great product, fast delivery
