Watch out for the crap reproduction hoses that have a very thick wall. You'll break the heater core putting them on.

They also don’t seal well with Corbin clamps too. My friend with a 69 Hemi RR fell for those things - they are huge, dont know how he evem got the clamps on them. But they leaked and he had to add screw clamps to them.

I always use a white pipe thread sealant. Seals perfect, and non hardening so you can get them off easily in the future.
