Where to buy V band clamps and rings at a good price

[s2_wot]

Looking for 3.5" V band clamps and rings in stainless 304, they seem to be priced very high in any of the usual places.

Shane very careful here... I had problems with 4" ones. The ones priced at £100 turned out to be cast flanges. Rather than CNC machined items i found out after i had welded 90% of the flange on then it just... well ****ed!

Many thanks for the words of warning.
I could get some machined up but the quantity I'm after wouldn't even come close to covering the cost of the writing the programme, let alone materials, machine time etc.

Did you weld yours up completely in the end?

I binned them and brought some more.

Its Jap/Chinese crap and i have a un-writen rule about it

I can not remember where i re brought them from But my 3" clamps and Bands i got came from Repo and they are pretty much the dogs bollachs

Mounting face i found another i put a welding rod about 8mm in there

That sort of result is pretty heartbreaking no matter what the application.

So I'm now looking for proven good v band flanges at the right price. Might reconsider having them machined, at least they'd be right.

This is the place i used for the larger flanges and clamps

James,
Just wanted to say thanks again for the heads up on the cast items. The world is polluted with them by the looks of it. I'm going to get some machined up I think. At least I'll know they're right.

Try Repo first Shane might save you some money

Absolutely no sense in making the vband flanges out of stainless. I have never used stainless bands, since I first tried, and they warped when welding, so the joint leaked no matter what I did.

Never ever had issue of corrosion or anything else with machined mild steel flanges welded to stainless pipe.

I have plenty of Vband kits. 102mm (4 in) kit with flange pair and a vband costs 75 eur. Equivalent 89mm (3,5in) 64eur.

Magic, thanks Repo, will drop you a pm in a while.

@Repo - Do you do a 70mm or 2.75" V band?
