Black Hi Temperature EPDM Rubber Hardwall Wet Exhaust Hose, 1.50 Inch ID, Up To 57.00 PSI

Continuous operating temps up to 250 degrees F are within spec for this hose. The EPDM rubber construction handles that heat without degrading, and it also resists ozone and exhaust gases on top of that. Just make sure it's installed far enough downstream from the water injection point so the actual temperature at the hose location stays within that limit. If your setup runs hotter than 250F at that spot, you'd be looking at a different material like silicone rated for higher temps.
