If there is sufficient interest, I can enquire what other colours are available. Once the tooling is ready, colour choice should not be a problem. The Material is I suspect in fluid form and I guess easy to swap colours. Maybe wrong about that. Unless I misheard, apparently I would own the tooling but, they would keep it at their premises. I suspect for competition reasons.
Sounds positive I think you can work out the colour I would want by my avatar 😁

I'd be happy with the Blue, but Yellow would be nice for ole Yella.

Yes, VVC-G ... I have seen those. I even have them in my ebay watch list and black versions. I also bought a black and red set like those for my MG Montego Turbos when I had some of those cars years ago. The red car was vandalised badly so I never got round to fitting the red set. The black set I keep in reserve in case I need any hoses for my only MG Monty Turbo I now have on long term SORN.

When its warmer, I will get the Red Set down from the loft and put them on ebay.

I'd be interested... if nothing else, at that price it makes a cheap reliable spare :-)
Might be worth setting up a list somewhere to keep track of everybody who is interested.

I do not want to be tarnished as a detractor from silicone hoses, I have used them and considered them on other cars, but a friend of mine is an expert in this field, and classic cars being the editor of a few mags.

We were having a discussion on using these hoses in classic cars and he gave us this information that you should consider. You may say he has an axe to grind but he is well respected in the field.

I reproduce an article he wrote after we had our discussion.

Your Editor has to advise you that he has an interest in a rubber manufacturing concern who produce cooling system hoses for many classic car clubs and specialists. We often get asked about silicone hoses and the following are a few disadvantages of this material. I would also add that if you do fit them to a vehicle that you must not use traditional jubilee clips as the sharp edge will cut into the material.

Silicone Hoses Disadvantages.

Permeability to oil and fuel.
The molecular structure of silicone doesn't play well with oil and other oil based products. We do not recommend using silicone hoses for any applications where they will come into contact with fuel or oil.

Permeability to water molecules.
Silicone is watertight, but water vapour can escape very slowly through the walls of the hose. Think of a balloon that you blow up with air and leave on a table for a week. The air escapes very very slowly through the walls of the balloon. There's a similar effect with silicone and if you have silicone hoses you will find that you have to top up the radiator from time to time , not because of a leak, but because of the water escaping through the walls of your hoses.. While silicone hoses are a must for racing applications some people do not like them for daily driving for these reasons.

He then goes on to explain the benefits of rubber hoses and the problems found with the readily available cheaply manufactured imported ones. THey use Kevlar reinforcement and not cheap fabric found in the imported ones causing them to soften and fail early.

So the information he gives makes silicone, in my opinion, to be something to probably avoid. We use them on intercooler hoses where they get into contact with fuel and oil, and cooling systems. I know my Rubber hoses lasted 130,000 miles but looking at that info will the silicone? Only time will tell but for me now a good set of uk made rubber ones are preferred.

Default As always, the choice is up to the individual.

Interesting topic.

With coolant hoses, there should not be any contact with oil or fuel. The negative qualities the "expert" has found with Silicone hoses are all precisely those I have found with Original Equipment RUBBER Hoses I've have found on my MG ZT 1.8Ts... all six of them. Has expert research data involved hoses on ZT Turbos?

In addition to fatigue fracture as my earlier images show, both along manufacturing seams, more recently TWO OE rubber hoses have shown negative signs of coolant escape I have previously described as "bleed" through the very structure of the rubber composite material. As per your balloon slow escape scenario.

So on that evidence available to me, the best as it's from my own eyes and experience, BOTH materials have longevity issues. In fifty years plus of car ownership involving many cars, the only time I have had hoses let go previously was due to rubbing against sharper parts in engine compartments from the vibration caused by normal running. Bleed I have not seen before although it may have been there unseen by my non-expert eyes.

One thing I have a strong suspicion of, the material used for hoses in all the MG ZT and ZT-T 1.8Ts I have experience of, are not of the same "longevity" quality all my previous MG, Rovers, Austins and Morrises hoses had. I have been impressed with the Silicon Hose fitted to one of my cars despite it not being designed for this particular car. It is far stronger than the Rubber originals it replaced.

Previously I bought two sets of OE complete rubber hoses assemblies for the 1.8T ZTs. Label dates show 2002 and 2004. No question, the rubber is nowhere near as substantial as the Silicon ones. Softer and more flexible than the top hose on my MG ZS 120 which I have had from new.

As always, the choice is up to the individual. I have chosen...

Finally, Silicon is a non metallic element whereas Silicone is a word used for any material compound using Silicon.... apparently. I thought it was a UK/USA word thing..

I considered Silicone Hoses - In the End i opted for a complete set of Original hoses £100 with PRT and all connections the Original hoses on my Car lasted 14 years and (almost) 90k WITHOUT failing time will tell on the New set i fitted.


OEM Looks Tidier too
