JIUWU White Fittings Bulkhead Connector 1/4-Inch Tube Quick Connect RO Water Filter Pack of 5

No problems. I used 3M 5200 as a sealant to ensure a permanent bond.

Only needed one, but that one worked fine. No leaks.

Thanks

Come on guys. It does not have the tubber washers which are custome order and cant be found at local hardwere stores. Include the rubber washers and advertise ait and charge more. Its not the price. Its a pain in the butt to find.

Worked great. All sealed great and were compatible to use in a dosing pump system. They shipped immediately and they arrived in the middle of North America from China sooner than expected. There are no gaskets included between the bulk head nuts but these sealed, screwed tight and worked so well, I reordered. Should I need more in the future, I will not hesitate to order this product from this vendor again.

Good product, but needs washers - had to make a separate purchase of washers.

These worked great for the plastic bucket drip irrigation that I made for trees I planted. They did not leak even without washers. You do have to be careful not to overtighten.

I was not able to get these to hold water. They leak right through the front as stated in other reviews - not around the sides where I added hose washers.I tried with two different materials of tubing, both with the correct diameter and had the same result. I was sure to push the tubing ALL the way in and had it cut perfectly straight. I ensured that the clips were fully seated under the tubing lock ring. I even tried adding a little petroleum jelly to see if it would somehow help the seal but it leaked in all my tests.A very slow leak, but still a leak which defeats the purpose of the part. Since watertightness was my #1 criteria in buying this product I have to say 1 star.

Great connectors, did the job for what I was doing.
