Suction Hoses
Reinforced with an embedded helical steel wire that prevents vacuum-induced hose collapse, these suction hoses guarantee continuous, uninhibited supply to hydraulic pumps — an unobtrusive yet crucial link for uninterrupted circuit operation.

Key strengths & applications
Vacuum resistance
The steel helix embedded in the wall keeps the bore open where an ordinary hose would collapse.
Pump protection
Steady upstream supply limits cavitation and preserves the service life of the hydraulic unit.
Generous flow
Flexible wall and smooth bore to reduce pressure losses on suction lines.
