Unfortunately had to use the continental branded sealant in my car for a puncture last night. Does anyone know if the replacement bottles are all a standard thread? The continental replacements seem quite expensive.

Do you mean the thread on the tyre valve, or some other connection?

It’s not clear.

Where the sealant container connects to the electric pump.

All car tyres use the same size schrader valve.

If they didn’t then filling them with air at the petrol station would be an absolute nightmare.

I am aware of that thanks, maybe I should have been clearer but that wasn’t what I was asking.

The emergency sealant cans I have used all connect to the air valve of the tyre. You then use the air pump later to pressurise the tyre. I would not connect the sealant to the pump, it will ruin your pump.

A lot of you answering this do not understand the question that the OP is asking... maybe you are unaware of the manufacturer supplied OE tucked in the boot of many a spare-wheel-less car... Google 'oe tyre sealant' to be enlightened.
In answer to the OP, I don't know for sure, but I very much doubt that they are 'universal'. All I do know is they are very expensive, which is why I always advise family and customers with lease cars to buy the aerosol types to use in an emergency, and leave the OE canister well alone!

Seems I'm among those not understanding this system, the ones I've had in the past are aerosols that connect to the valve, much like a pump.

OP, did you recycle the bottle. If not maybe swing along to you nearest Halfords type place and compare the threads on them?

Edited to add a picture which should help explain assuming this is what you've got biggrin The orange cap unscrews and bottle screws directly into the pump

I can check mine when I get a minute, but because the pump can be used to just inflate the tyre OR to put the sealant goo into the tyre, I think they use a standard schraeder connection, otherwise you'd need another connector.

In that case you need to clarify what you're asking.

The kits I've seen consist of a bottle of goop, a cap with a hose coming out with an end fitting that connects to the valve on the wheel, and another fitting the same size as the wheel valve which the pump connects to. The pump pressurises the container, the goop is pushed into the wheel.

I would not expect the cap to be reusable since it ends up filled with goop. The replacement should consist of the bottle plus a new cap.

If you're buying a cap and bottle, the only fittings that have to match anything are the air connections in and out. Those are all standard valve connections.

If you're only buying the bottle then I don't expect there is any standard for the thread so you'll need to match the cap you plan to use. Is the original cap still in a usable state?

You still aren't getting what he is asking.

Look at the pic in the post above yours.

The big orange screw on the pump allows the tyres to be topped up when it is in.

When you want to try to seal a flat you remove it, screw in the cylinder of "goop" and then pump the tyre up, which pushes the "goop" into the tyre.

The OP is asking if the "goop" cylinders have a standard thread?

No. They have completely random threads so that nobody has a clue what to expect, which adapters to buy etc.

I would have thought you're better off just buying something like this one. I imagine the screw in continental one also requires that you replace the hose and part you screw it into too as they sell replacements for that as well. I have one similar to the one above and you just use it inline with the compressor. The whole lot is self contained.

I understood the OP's question, it's just that my equivalent of that kit works a different way, so my answer reflected that.

I know they don't mean the aerosol cans, they mean the pumps with a separate big tub of goo.

My big tub of goo is clearly different to that big tub of goo.

Which, at least, does answer the question - no, they're not all the same.
