Stainless steel Exhaust U clamps? for JP Exhaust

[Cruz]

The (formerly) zinc plated exhaust clamps on my JP Exhaust are looking rather worse for wear now after 4/5 years and I was wondering if anywhere sells stainless steel U clamps?

I need
4 x 42mm clamps
3x 48mm clamps

I have found 42mm clamps at U bolts R us for £30 for 43

and 48mm clamps on ebay via poland for £16 for 3
all are 304 stainless

Would these be ok strength wise, and does anyone know of a place that sells both 42mm and 48mm stainless clamps (that may be cheaper)?

[R0B]

I am after the same.

Just realised its been on for 2 years. feels a lot longer. why did they not fit stainless clamps in the first place grrr

[R0B]

Just rang a mate who works at jp exhausts.He recons the stainless ones keep working loose.Otherwise they would be using them.I suggested using two nuts,one as a locking nut.He said they have tried that and they still work loose.He suggested trying the MIKALOR type clamps.But that means stripping the exhaust.

[Cruz]

I am inclined to agree Ian. Just have to remember to change them more regularly than once every 2.5 years

I'll have to cut some off they are that corroded

42mm £0.99 http://www.ebay.co.uk/itm/Universal-Exh ... 2392wt_836" onclick="window.open(this.href);return false;

48mm £1.79 http://www.ebay.co.uk/itm/48MM-1-7-8-In ... 2194wt_963" onclick="window.open(this.href);return false;

So £9.33 all in

[Ian Hulley]

Rob, Mikalor clips can be undone and bent round the joints ... we use them here ( ) BUT I'm not sure they will go tight enough without stripping the thread in the clip. Plus the band itself may be stainless but the bolt/captive nut isn't.

He recons the stainless ones keep working loose.

Then use stainless aerotyte nuts ... we use them as well

Ian.

[Cruz]

So what are we saying now?

Stainless U clamps with aerotyte nuts?

Found 42mm stainless U clamps for £4 here (from Poland) http://www.ebay.co.uk/itm/181140962550? ... 1994wt_726" onclick="window.open(this.href);return false;

Though they don't seem that heavy duty to me

[R0B]

Thats what i would like to try.Its the cost (forty odd quid) that's holding me back

[Cruz]

That's not even accounting for the cost of the aerotight nuts (in my case) which pushes it up to nearly £60

I can change the mild steel clamps 6 times over for that

[R0B]

I can get the mild steel fer nowt.(I know a man) Looks like thats what i will do.Again...

[Cruz]

Ah well. It was worth a try.

We have PRC (sealant) here that we use on parts that are near the engines on military aircraft that I may use to overseal the nuts, which should make them easier to get off the next time

[R0B]

Thinking about it its my nuts that are in bad shape I might just try aerotight nuts on the mild steel clamps.

The U bolts on mine have crumbled to half their thickness in some cases
