There's a silicon tube avalible in many different dimensions ,it only smolders if it's too near the flames I've used it for years on the bits that don't get hot,It looks like a semi clear plastic pipe but it 's got great friction ..I buy it from a hardware shop it's quite cheap...The main problem is getting it over the staff or whatever cos then the friction stops it sliding on-I use chalk dust to help it on or washinp liquid.The other problem was when I ask for silicon tube they always assume I want the sealent that comes in a tube...ciao for now
