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.
- Meets SAE 20R4 and 20R3 Type EC Class D-1 and D-2 specifications.
Temperature Rating: -40° F to 275° F (-40° C to 135° C) in coolant hose applications.
