Corrugated Black Hi Temperature EPDM Rubber Hardwall Wet Exhaust Hose, 3.00 Inch ID, Up To 60.00 PSI

It's designed to withstand continuous temperatures up to 250 degrees Fahrenheit, making it suitable for wet exhaust and engine coolant systems.

The inside diameter is 3.00 inch and the outside diameter is 3.6 inch, so it matches a 3 inch ID wet exhaust connection while giving you a little more bulk on the OD for clamps and clearance planning.

Placement matters more than most folks realize with wet exhaust hose. The hose needs to be positioned far enough past the water injection point that the temperature at its location stays under 250 degrees F continuously. That's the rated ceiling for this EPDM material. There's no fixed distance that works for every setup since engine load, water flow, and system layout all affect temps at any given spot. The goal is just making sure wherever this hose sits, it's seeing cooled exhaust mix, not raw hot exhaust gases.
