NO!!

These are not the same clips, they are the same type of clips, but the link goes to a page with clips very much smaller than is needed.

I know because I took the link and bought the clips.

I do not know which of them is the actual correct size, but the 3675 is not correct.

Just ordered a pack based on your recommendation! Thank you!

Yea confirmed those are not the right one. They actually weren't too small. It seemed like the legs actually expand too far and get stuck in the hole's bore before the legs reaches the other side. I was able to clip a little bit off both of the legs and it worked just fine. But it's certainly not the same.

Hi Peter,
I've recently just bought the BDB and saw this Mod you did. Just a quick clarification though,


Is this fitting you got the same as this one from amazon?

If anyone else has successfully done this mod, if you guys don't mind confirming this for me as well. Thank you again for all of you guys' input.

Peter hasn't been active here for a while.

I've done the mod and helped others out with it. There are a couple of concerns with the fitting.

1: hose and pipe compatibility. I think you are good to go. You need 4mm hose on the press side. Check. You need 1/8 bsp on the OPV side. There are 2 kinds of bsp. Bspp - bsp (parallel) and Bspt- bsp (tapered) I know the vibbimme brass OPV is 1/8 bsp but I am not sure which one. This part does not specify either. But, honestly, I think you could make either one work since the part has the o ring at the top.

2: temperature rating. The water moving through the pump is room temperature so you are good there.

3: pressure rating. This one is only good to 145psi, which is like 10 bar. I would want one that is rated higher than that incase I had a problem with my OPV sticking. You pump will put out pressure well in excess of the capacity of this elbow. I would hate to have the fitting burst, if my OPV failed.

So, in short. I would not use it. I think I'd take a chance on issue 1. But issue 3 is a no go for me.

These can be pretty hard to find via Amazon. McMaster Carr has them reliably but the site can be pretty hard to navigate. Sadly, I am not in a place where I can find the part for you. Maybe you can take a look or someone else can post a link.

Hi lancealot,
Thank you for responding. Read a lot of your posts too. Its great to see you are still active here. So here's what I found.

Would these work? But man they are quite pricey.

Happy to help. They're expensive cause they're stainless. I searched my order history and came up with these.

This is the pressfit one:

This one is a more traditional compression fitting
https://www.mcmaster.com/product/3868N193

I had a pressfit fail on me. The press fitting would not hold and the tube came out under pressure. It's probably my fault for messing with it too much. After that I switched to using the compression fitting.

Great!! Thank you so much!! I think I'll go and get the second one. Since this second fitting has an O-ring, did you still have to apply PTFE tape before installing it?

One more thing though, if you wouldn't mind explaining to me why Jake said in this video guide that we have to cut the tube before connecting it to the elbow compression fitting.

I have zero experience in plumbing so I apologize if this question seems stupid.

This is the compression elbow I used. Honestly been so long I don't remember if/or why line has to be cut.

Since the fitting has the o-ring, It won't hurt to use PTFE tape. You probably don't need it but why not.

You have to cut the tube because it wont fit into the compression fitting with that brass ferrule on there. You cut it, slide the cut end into the compression nut and then slide the new brass ferrule (comes with the elbow) onto the tube, then connect all this to the elbow. I think the video is pretty self explanatory. I'm sure you will understand it once you have the parts in hand.

Two things to note:

If you buy the compression fitting I linked to, it swivels. You'll thread it into the OPV, tighten it up enough to compress the o-ring, when it is tight the elbow will swivel so that the output can go in a natural direction. Notice how his pointed to 7 o clock in the video and made the tube bend in an odd way, yours won't do that. I'm telling you this so you don't think that you have to keep tightening it to get it to stop swiveling. You can over tighten that part and strip the threads, they are brass. Tighten it till it compresses the o-ring and you can't tighten it anymore using moderate force.

Second. The point he makes about not over tightening the compressing fitting is important. I don't know how to communicate how tight it should be. Just remember that as you are tightening it, you are compressing the brass ferrule onto the soft plastic tube. You want it tight enough so it presses into the tube a bit to prevent it from coming out, but not so tight that you cut or damage the tube.

Good luck. You've got this!

Oh man I actually purchased this but it takes too long to get to me. And I realized after 2 days of ordering it that I couldn't wait that long and its too late to cancel.
