High Pressure Hose

High Pressure Hose

CEJN
Best Seller

Features: The CEJN High-pressure hose is a spiralized steel reinforced polymer hose that picks up where conventional product capabilities stop. It gives you ultra-high working pressure with maintained flexibility through entire life. Its low volumetric expansion gives fast response time in hydraulic systems while the smooth inner bores provide a minimized pressure drop. A long-lasting service time and extended hose life in even the toughest applications is a result of the kinkresistant steel-reinforced construction, abrasion-resistant covers and a superior chemical resistance. The small outside diameter makes the hose ideal for tight routing.

• Ultra-high working pressures
• Maintained flexibility through entire service life
• Low volumetric expansion
• Smooth inner bores
• Kink-resistant steel-reinforced construction
• Abrasion-resistant covers
• Small outside diameter
• Superior chemical resistance

Swivel Connectors

CEJN

Features: Available from CEJN are swivel connections for high-pressure hydraulic applications. The swivels are especially suitable for use in confined areas and for bolt tensioner tools, torque wrenches, cylinders, bearing pullers etc. The swivel connections offer increased flexibility for hose kits and their swivel function allow a 360° movement up to full working pressure. This ensures that no twist or torque is transferred to the hose. As a result, the hoses’ service life is prolonged and the handling is made easier for the operator.
