Feser 45 degree rotary barb - how are they for leaking?
 

I would like to pick up a few of these for my loop but I've gotten it into my head that I've read something about these being prone to leaking.

Anyone have experience with them that can comment?

They probably didnt tighten the fitting very well.

I have 45 rotaries (at least 4) on my rig and no leaks (knock on wood).

I have used the Feser and the bittspower double rotary. If you do take care to tighten correctly and you wont have any problems.

Excellent! I'll pick some up for my loop.

Thank you gentelmen :)

Don't put too much stress on the rotary and you should be fine. I've had a few of mine leak but just leasoning the tension and wiggling the rotary usually resolves it.

Like the others have said, it usually has to do with how much pressure/ tension is on them. Sometimes, rarely though, you will find one with a gimped inner o-ring, and will need to exchange it, but I don't think it happens often.

Once again = Thank you gentlemen :)

Ya the when you tighten the barb (too much... too little) is always the delicate part of an H20 build IMO and you get a "feel" for it with experience.
Good to know it isn't a design/engineering or QC flaw though.

Just put my 45 rotaries on today, mine are bitspower though, but since I'm typing this message, they're not leaking ;)

Mine leaked
 

Old thread, I know, but just wanted to put in my 2 cents in, since the thread is still open.

I bought two feser 45 rotaries (the same ones as in the picture). Half a year later, one of them started leaking from the smaller fitting. It was screwed on tightly, but I could jiggle it in it's place.

It started leaking pretty badly a few months ago so I super-glued around the fitting as my solution.

The other one hasn't leaked at all.
