Legris 6316 60 00WP2 LIQUIfit Push-to-Connect Fitting, Inline Bulkhead Union, 3/8" Tube OD

I used one of these to turn a 5 gallon bucket into a reservoir. I added silicon to the bulkhead just to be safe. It's working well.

I purchased this and seeing the review of the customer whose fitting was leaking I thought I had received a bad one as well. After messing with the tube several times it still leaked. I got a closer look at it and realized it was leaking through the threads not the hose connection. Just added teflon tape to the treads and that fixed that.

I try my best to avoid posting negative reviews and clear things up with the seller... but these things leaked (I ordered 2, both did.) I used 1/4" OD Polyethlene tubing as well as tested them with 1/4" OD clear plastic tubing, being sure to push the squarely cut tubing in as far and as snug as possible. No success with either, and seemingly no way to get in touch with the seller. Slightly disappointing, but not worth the $ to ship back and try to return.

These worked great for the lids on my BRS calcium and alkalinity containers. I have a Bubble Magnus dosing pump and needed to route 1/4" tubing through the containers. These give the setup a professional look. Just drill the hole and screw these bulkheads on. Super simple.

I installed this in a 5 gallon container to make it an auto top off for my saltwater tank. i used 1/4" water line and plumbed it to a float in the sump. no leaks and is a quick disconnect if i have to move the tank.

These are high quality, durable, and the Push-to-Connect is even airtight with the proper hosing. Get these to mount hoses through any flat surface!

Works then doesn't, anytime the tubing gets moved it drips, until re-push. Maybe I just got a bum one, as I haven't tried others of this brand.

This fitting is well constructed and easy to use. It's made from quality materials, and although I haven't put it in use yet, I would have complete confidence it will serve it's purpose well.
