Rubber seal for MPK roof light vent

[Autoroute]

My van was supplied with a MPK roof light vent in a "permanently vented" "free air flow" style with half of the roof light unsealed. Initially I thought it was a fault but it's mentioned as an option in the installers manual.

Now that might work well in sunny climes but here in the windy north it creates a noisy cold draught.

I only need about 80 cm length to seal around the whole vent. Image of the profile attached.
Does anyone have any spare? Any ideas?

I've found some online however even the delivery charge is extravagant.
Thanks.

It is like that because all motorhomes require a certain amount of ventilation when in use and that is the cheapest way to provide it.

Our motorhome has fully sealed roof lights but it also has 2 small roof vents to provide the required ventilation.

Very good to deal with, I wasn't sure and they sent some samples to try before ordering.

I'm not a lover of MPK and changed ours for non vented Heki apart from the bathroom so much quieter when travelling. Bob.
