I ordered a full set of Silicone Hoses from Moss for my MGB. They are still on back order. But when received I'm considering installing them with the Gates Heat Shrink, power grip Hose clamps. Has anyone used them on an MGB before? If so positive or negative results?
Thanks;
Chuck

Are you sure those are for silicone?

FWIW both my cars only have Silicone hoses (Samco in the MK1 and ASH in the GT - no usual suspects kits for me) for coolant use. I preferred to use worm clamps - the type that don't cut into the silicone.

Barrie:
I called the Gates help desk and they said the heat shrink clamps had been fully tested on Silicone hoses. So that's all I'm going on right now. I'm hoping someone who is or has used them on Silicone hoses with the MG's can tell me how well they work. A friend of mine installed Silicone hoses and used the heat shrink clamps when he overhauled his 1970 Corvette, and is pleased with them. His only caution was to buy the special removal tool with the hoses.
But that's just a sample of 1. I appreciate your response.
Thanks; Chuck

So I just watched a Utube video - seems like a good idea but they are a one time clamp so for mine they should only be used once you're satisfied that you won't be undoing them any time soon - not an option for me currently on the GT; and it looks like you need the removal tool. How does price compare to a "normal" clamp.

I haven't used them on the rad hoses, but have installed the Gates Powergrips on the heater valve.

I have a solenoid style heater valve installed.

I used the Gates clamps to reduce the clutter of four regular style clamps.

The Gates Powergrip clamps hold well. However, they are one use only, are a bit expensive, and require a special tool to remove. Even with the tool, I had to cut into the clamp with a knife and damaged the hose.

I have avoided using them on the rad hoses because of these qualities. Should I have a problem on a road trip, I have many more options with the regular clamps.

I have a buddy that installed silicone rad hoses on his B. He had to go with a constant tension bolt-type clamp to achieve a good seal.

Mmm this is about radiator hose size so @ $AU55 for one I'd be staying with worm clamps for silicone.

Ouch! Barrie, I hope there are other available sources for you in Australia.

They are under $3 US at most outlets.

Looking at the prices. They run between 2 to 3 dollars each depending on size and vendor. More expensive than regular clamps, especially if you already have a box of the standard clamps. Once I get my silicone hoses, will probably try on the heater hoses as a test. If they seem to work ok then will move to radiator hoses later. But will keep a set of the standard clamps in the road repair bag, just in case on a trip they give me a problem.
Thanks for the responses from everyone.
Chuck

I didn't search very far Ron so that may be an aberration - I stopped when I saw that.

We installed them on the Zetec car and they've held up well. Much cleaner look than clamps.

They make a special tool to cut them should you ever need to remove them.

Hi Chuck,
As said the heat-shrink clamp system is a novel idea but is not service removeable, which will make field repairs much more challenging.
Silicone hoses have a much longer life than regular rubber, they are seen frequently in heavy-duty trucks, tractors and construction machinery both for cooling and induction system use. I avoid them on my vehicles simply because the cheaper ones tend to tear and nick easily, and those will spread easily and destroy the hose should this happen. What I've chosen to use instead is Goodyear Hi-Miler Blue heater and radiator hoses where I can, because of the higher heat resistance threshold they have a longer life, and their EPDM construction allows the use of regular clamps and general handling procedures, even after many years of underhood time they withstand field repair quite well. Just food for thought. Cheers.

David:
Interesting about the Goodyear hose. May try it after I go through the silicone. Never heard of it so thanks.
Ron:
$37.08 for the tool seemed pretty excessive. So I called the local NAPA dealer and was told $17.00. They would discount that, if I bought the Shrink Clamps from them. But we all know prices differ greatly depending on where you go.
I do appreciate the information.
Chuck

Yep, but you do have to get the exact size as they are limited in their travel when tightening.
