Marketing Description

Gates Molded Coolant Hose is manufactured to fit specific applications. Similar to OEM specifications. Approved for marine applications.

Recommend for upper, lower, by-pass, heater and other coolant hose applications.
Heat and ozone resistant cover.
Engineered to resist electrochemical degradation - the leading cause of hose failure.
Re-engineered materials resist vacuum collapse. This reduces the need for internal springs in many applications.

Temperature Rating: -40 F to 275 F (-40 C to 135 C) in coolant hose applications.
