Silicone RTV sealant will satisfy the waterproof, temperature, and
flexibility and with the right brand will not be effected by sunlight (see
label) but if your system is pressurized it might not be strong enough to
resist leaks.

Perhaps you can insrt a rigid tube (metal, glass, plastic) inside the rubber
tube and clamp onto that surface. If tight enough, no sealant would be
needed.

I have a rubber solar panel system to heat my swimming pool.

A few of the small rubber tubes have cracked and are leaking.
Anyone out there know how to go about repairing them?
I did a google search and found only one instance which described this
problem and the possible fix (using flexible tubing - not detailed on
the repair procedure). I would prefer to use an adhesive if there were
one that could withstand the heat being generated by direct sunlight
and the chemicals in the water passing through the repair joint.

TIA to all who reply.
