Buses, cranes, trucks, mobile/heavy-duty off-road equipment

E-Z FORM HT High Temperature Oil Resistant Hose

Series 7399 is an extremely flexible, lighweight, high temperature petroleum-based oil suction/return hose designed to resist cracking and deterioration for the extreme heat generated in Tier IV engine compartments of buses, cranes, trucks and mobile/heavy duty off-road equipment. Series 7399 may also be used in non-SAE power steering applications (as a low pressure return line only) and is capable of being routed through confined spaces where formed hose might normally be required. The lightweight Greek corrugated hose construction incorporates a wire helix that provides full suction capability, superior kink resistance and minimal force-to-bend. the unique corrugations are tightly pitched and precision-engineered, providing extreme flexibility compared to the traditional rounded corrugation profile. The cover is resistant to high temperature oil in high temperature environments.

NOTES:
Do not drag across sharp edges or highly abrasive surfaces.
For E-Z Form standard multipurpose oil resistant hose, refer to Series 7219.
For E-Z Form coolant, vacuum and water hose, refer to Series 7395.
