Need to replace FX4 hose with non ribbed hose, which one?

  • We are currently upgrading MFK. thanks! -neo
How do you connect this the FX6 aquavalve? Since it is ribbed, does the hose clamp still work without any leaks?
1” Corrugated pond tubing for FX6?

How do you hang it on the tank side?

I don’t care for the fx hose clamps either, hose too stiff, hose clamp on tank does not stay straight but direction of hose angle.

Did your FX6 come with these brackets for over the side ? As far as the clamps go, you can just go to Walmart or auto store and get regular hose clamps. I like stainless ones though, no rust problems.

Yes, it came with that hose mount. The included fx hoses convert to the white rubbery part which is smooth, the tube clamps goes on there.

The corrugated hose is ribbed so if you same clamp, will it leak? That was what I was checking.

Hmm, I’m not sure on that a spot I’ve not had to replace any yet. Maybe we can get Oughtsix Oughtsix to chime in.
 
Yeah, I get it. I’m going to buy it when I have to replace mine. I would rather have the smooth inside. Easier to clean.

Are you asking about the corrugated pond tubing?

It does not come with any connectors... and can be a bit of a hassle with the inch vs metric filters. I use sumps so I just buy the pvc connectors that fit. A couple of local homedepots stock the corrugated tubing for close enough to online prices that I buy it there if they have the size I need. It is in the pond department.

There is no spiral path for the water to leak through if you get a tight fit on your connectors. I always put the ends in boiling water before putting the connectors on... Just like every tubing.

I have been using the PEX pipe pinch clamps lately. They provide a lot more clamping pressure. But are miserable to remove if you ever need to.

Yeah, my local Home Depot had it this spring. I haven’t needed any yet though. Nothing wrong with adapting a connector. We were asking about what to use for a clamp on the ribbed hose? I hate pex, it’s a pain in the butt to redo it. I’ve had motorhomes with that in it.

These are the crimp clamps I have been using on all of my tubing lately:

They are commonly used for Pex because they provide so much clamping force but they are available in just about any size you might need (through the internet). Not only do they clamp REALLY well they don't leave the excess band hanging out so they are a lot neater and don't get in the way when you have a lot of connections next to each other.

To remove them you have bend that little tab up then pull the band off of the tab. They are one time use. And they are a royal pain when you do have to take them off!

The reason I keep mentioning HomeDepot is that you can take your fitting/connector to the store and test it on the hose before you commit to buying it. On occasion I have chucked a PVC fitting in my lathe and made the perfect diameter barb to make an exact fit for a weird hose.... not everyone has this capability though. So although I love the pond tubing and use it extensively I would hate to frustrate someone that might buy the tubing then find it won't work with their connector.

Previously I used QUALITY screw type hose clamps and they worked well. Cheap (Harbor Freight or even Homedepot/Lowes) screw type hose clamps have never worked well for me. A while back I bought a bunch of quality screw type hose clamps (and paid dearly for them) which restored my faith in them.

I always put which ever type of clamp I am using on when the hose is still hot and soft from dipping it in boiling water. I feel it makes a tighter clamp that way... but that is just my opinion... nuthin to support it.

Hi!

I saw your post about using corrugated pond tubing for your filters. I picked some up and have installed it on my Fluval FX4, but there is a very slow leak where it connects to the filter. I have a hose clamp on it, but I think the seal is not tight because of the corrugation. Do you have any advice on how I might fix it?

Thanks!

The corrugation should be on the outside of the tubing only. The inside of the tubing should be smooth. With a good tight fit I have not had an issue with slow leaks when using the corrugated pond tubing.

1) If the tubing is a tiny bit too big for your filter fitting a couple wraps of electrical tape and a bit of silicone will most likely solve your leak problem. I have also used a 1" long piece of thin clear vinyl tubing to fill in between the pond tubing and some slightly smaller connectors.

2) Heat the pond tubing in boiling water so it is very soft before clamping the hose clamp. With the tubing soft and the fitting built up a little bigger than the tubing the silicone sealer will act as a lubricant to help you slip the tubing over the connector and when the silicon dries it will give you some additional gap filling leak stopping help.

3) Forget about the screw tightening hose clamps. Purchase the correct size of pinch / crimp hose clamps:

I use a pincer (a type of nail puller available for cheap at harbor freight) to crimp these:

4) When you need to remove the hose clamp down the road some time forget who I am and that we ever talked! The pinch clamps are removable... but they definitely require a good bit of cussing the first few times you try to remove one.

Good luck and let me know how it works out,
Michael.

P.S. I have scored hose barbs on fittings when cutting the old tubing off the hose barbs with a knife before. This will cause a very slow leak through the score line. The bit of silicone should help seal a score line if the barb isn't easily replaceable. I suggest letting the silicone dry for at least 24 hours before putting it back into use.
