Coolant Hose for Heavy Duty Engines 881272

Coolant hose for heavy duty engines are required to provide long service life under very demanding conditions. To develop a coolant hose/joint assembly to meet these requirements, a life cycle test rig has been developed that can closely simulate engine conditions in heavy duty applications. Hoses of various materials, reinforcement and construction were tested for up to 2000 hours and evaluated for retained burst strength, leakage, and serviceability. The test has correlated very well with field experience.
