Large diameter, thick heat shrink

[RaceDiagnostics]

Does anyone know where I can buy heat shrink this size?

The shrunk dimensions are;

i/d is ~24mm
thickness is ~2mm
length 450mm

Looks like this and is used to protect a power steering hose in the engine compartment.

Thanks.

How about this, https://uk.rs-online.com/web/p/heat-shrink-cold-shrink-sleeves/0450515/
50/16 claims to have a 2.7mm wall thickness

I can probably sort you out with some if you know what the unshrunk diameter (or flat width) should be?

I’ve used these guys at my last place. Website isn’t that good. They are helpful on the phone

Thanks, it just needs to be bigger than the end of the hose in the pic above, so anything bigger than 30mm diameter or so that can shrink down to 24mm would be great.

Edit: I guess to get the thickness it would need to be much bigger pre shrinking, depending on the shrink ratio.

Give me an hour and I will have a look in the shed..

We use HD spiral wrap to protect hydraulic hoses from abrasion or ceramic cloth if it’s a bit toasty, I can’t see the point in using heat shrink

In my experience the wall thickness after shrinking is greater than before. With some I have here the wall thickness before is approx 0.35mm and after shrinking is 0.5mm

As with bob, I’d be trying to get some fire sleeve myself, hear shrink will abrade quicker than the hose will

I meant the od needs to be much bigger pre shrinking, to get the thickness.

The heat shrink I took off has been on there for forty years. Anyway, where can you get the sleeve you suggest?

The hose sits here, protection against the battery, air filter housing on top and heat from below?

Mercedes must have put it there for some reason.

For heat we use this ceramic cloth and stainless cable ties, it can be done neatly if the you give it a couple of wraps and keep the join underneath.

Probably, but from what I can make out Mr Race Diagnostic is doing his level best to keep the car original

it’s gonna be concourse A plus by the time he’s done

I have got some 60mm o/d thick-wall,
Stuff is like a drain pipe though so might be costly to post.
Or I have got 60mm flat width thin wall. You could build that up in layers to get the thickness you need?

I have got smaller or bigger as well but it's freezing out there so I can have a shuffle through it tomorrow if you wanted another size...

Thanks, PM sent.

If you know any BT guys, the adhesive lined heatshrink for underground cable joints is pretty useful, but has an interesting almost-camo finish...

I’d wager it was just a rubber sleeve when new, and has gone hard from heat and age.

I could be wrong though, it happened once before.
