is it ok to clamp spa flex?

Runfrumu · 08/10/2008, 07:49 PM

I was re-doing my return plumbing so i could put a ball valve and thought I would give spa-flex a try. Is this stuff ok to put on a hose barb and clamp down instead of gluing?

You should cement it with Weld-On PVC 795 which made for this propose.

thing is Im attaching it to my UV sterilizer and Im also planning on adding a chiller in the near future so i wasnt wanting to make it permanent just yet, I seen one reef site where a guy was using clamps and was just wondering if anyone else had done it without any problems.

thanks for the response though.

I wouldnt trust clamps on it.

I think it would be fine. I mean automotive companies trust them in $100k cars and the hoses on a car aren't exactly the same but there under alot more pressures than the average return line.

But cars dont use spaflex and aquariums dont have the metal barbs that cars do that alow alot more pressure from tightening

Why not glue in some unions

dj9264 · 08/10/2008, 10:53 PM

I'm also not sure the spa-flex fits the barb (too loose) and a clamp will not work on PVC; it's not like a rubber hose.

What about cementing the flex end on to a male adapter then into a threaded union? That way you are free to change the plumping at a later time. I do this with all my flexible PVC just so I can get it apart for cleaning.

Runfrumu · 08/11/2008, 12:30 AM

so how long should I give the cement to dry on the PVC if I glue in the unions and the spa flex before I can start running the pump again?

Also on the turbo-twist UV im running, it has a 1" barb and below it is thread, so what kind of bush or adapter would I need for that?

My return is connected to spa flex with just a barbed fitting.. Been like this for 2 years. Though its a Eheim 1260 with a metric fitting. I wouldn't try it outside of the sump though, just in case

I hooked spa flex up to a scwd with a clamp to barb.
I had to heat up the spa flex with a heat gun just to get it over the barb.
It would be easier to glue it. Just use a junction so it can be removed.

i appreciate all the help guys, one more question, my pump goes to a UV then up to the tank, would it be ok to put the ball valve after the UV or do I need to put it before the UV?

Thanks alot

why not just use vinyl tubing on a barb as intended.
