ok i have a miss match of coolant hoses, adaptors and jublie clips i want to remove, and i'm looking for a 20mm to 30mm hose reducer in rubber and a 30mm to 30mm joiner

i've done ebay and googled but not found one yet, anyone got any ideas please?

Have you tried demon thieves(tweeks),
rally design,car builder solutions,europa?
Have you got a local hose company like hyphose ?

I used

These

For my hoses. Great serviie but not sure if they have your sizes.

CBS will custom make hose joiners for you - great quality too

When i made up my hoses i just asked in my local motor factors if i could rummage through their pipes to find the bends and reducers i needed. They were quite happy to let me, and and I got all the hoses and bits i needed for about £15.

For the joiner how about a bit of 1.25" pipe. Thats 32mm, and with a jubilee clip on it wont leak.

Depends how 'locost' you want to be
