Bongo Fury

Having helped Northern Bongalow out with the Bash bleeding sessions (and of course "Kirsty" the newly appointed Bongonaught of the year) I have been looking at the types of hose clamps available,
It would seem that conventional "worm/screw" clamps may not be a good idea. the following info is quite enlightening.

These could be the answer to the weeping Sil hoses

Hi, there has been lots of talk about the issues of sealing silicone hoses, the combination of thicker silicone hoses, the natural tendency of the silicone to 'flow' away from pressure, and the wide temperature range the hose will be subjected to, means that constant pressure clamps, as used by manufacturers, are the way to go.

The clamps can absorb a lot of change in diameter , and also tend to be 'rounder' than the screw clamp type.

Also, DO NOT cut off the old hose with a knife, the spigot can be scored in doing this, leaving a leakage path.

The link Haydn posted is a good one, the hose and spigot and clamp is a system which must all work together for best results.

Are those constant pressure clamps ?? I don't think so.....!!
The problem seems to be that the constant Hot/Cold/Hot/Cold cycles are not compensated for with a "screw type clamp.......the "spring" clamps do expand/contract with the Spigot and Hose......as do the standard Mazda Bongo clamps

the choice of clip i think on a bongo maybe more important than on a racing application purely because it will live on a bongo for a long period of time,more cycles of temp, racing motors tend to be pulled apart and rebuilt,and things replaced more often,i cannot find anything better than a mazda clip and hose,checked and replaced at a modest interval you will have no issues.
a key thing i have noticed is that when a hose goes,there is usually an underlying issue running alongside.ie stat not working correctly.fans not cutting in,rad not efficient,
sorry to put this here but it is relavent to the topic generally.
