Oil hose fittings

So apparently worm hose fittings aren't allowed for connecting oil cooler to engine and to the oil cooler.

Any ideas on where to find these?
 
That's right - they shouldn't be used as they twist the hose while tightening the clamp. Better use this type:

They build up an even pressure on the whole circumference of the hose. Same kind clamp you'll find on the carburetor intakes...

Cheers,

Couldn't find hose clamps as such in the Speedflow catalogue. They do a compression type hose fitting that would be an ideal solution, but I suspect Carlo is looking for a quick/easy replacement for his worm drive clamps.

It's a bit of a challenge to find non worm-drive hose clamps in a small enough size for oil cooler lines, but these fuel injection hose clamps may be acceptable. They use a bolt and nut rather than a worm.

They go up to 17mm. The hoses on my Jota are 16.5mm OD so hopefully yours are about the same. The link above is for a supplier in NZ. If you shop around a bit on the web you should be able to find them in Australia. Search for fuel injection (or EFI) hose clamps.

Another option is double-ear hose clamps https://www.ebay.com.au/itm/Zinc-Plated-Double-Ear-O-Clip-Eared-Hose-Clamps-2-pieces-or-10-packs/272186431092?hash=item3f5f935674:m:mR9R7_zZFnGxs4MHTs0QzqQ
You just need a pair of pincers to tighten them.
 
The things you learn, I have used worm drive clamps on my oil cooler for the last 30 years. If you find something better Carlos let us know.
 
I use worm drive clips on my Jota too. Never had one leak or fail in any way. The problem for Carlo is that they aren't acceptable for racing. I presume one must have let go at some stage and hosed oil all over the track.

Actually, I use two hose clamps on each hose end, fitted 180? opposed to each other to minimise the hose deformation that Alex mentioned.

Yes, two at the oil cooler and two at the front of the crank cases  (bolt)
Actually, I think the rules state 'no clamped oil lines' in other words, compression fittings only.

 
I have to agree with most experienced Motorcycle enthusiasts - Use SIMPLE Industrial Hydraulic/Gas Hose with Heavy Duty Clamps whether its for Gas or Hi-Pressure  Oil Pneumatic lines.
