Yes, just call Rotechniks, they\'ll send you the hose that they normally use. Its a rubber one. Some people use Silicone, but its liable to splitting.

I have done half of mine but keep on breaking solenoids !  :reallymad

be very careful when changing these hoses they are very brittle!, i used some high temp silicon stuff it has a thick wall on it.

The trick is getting the old ones off. Where they join the solenoid or valve, cut it open gently with a stanley knife first.

Glen,
i have 2 reels (3 metres each )of samco silicone hose if you need it.  Did mine over christmas and bought too much from Demon Tweeks....

was gonna advertise it on the board anyway.

I paid about £12.00 (per reel) + VAT + Postage

You can have them both for £20.00 (and all the spare cable ties)

As long as you are careful with the silicone hose it is the best stuff for the job (according to the guys in the US).

Silicon doesnt last that long due to oil vapour in the system. You really want to try and get hold of some Viton tubing. 4mm and 6mm, but cant remember the amounts needed.

I\'m looking at doing my hoses soon. From what I\'ve read it\'s 35\' of 4mm and 10\' of 6mm. But I may be wrong

Does anyone know where you can get the Viton hose?

[maximtaylor]

I know ReWorx can source it, don\'t know of a direct supply line.
