Spiral Hydraulic Hose Pipe

Size – 1/4” , 1/2 ' , 5/8” , 3/4” , 1” , 1-½” ,

A spiral hydraulic hose is a type of heavy-duty hose designed for very high pressure applications and extreme working conditions. Unlike R1 or R2 hoses (which use braided wire reinforcement), spiral hoses use spiral-wound wire layers, which gives them superior strength and durability.

🔧 Spiral Hydraulic Hose – Key Features:

Reinforcement:

Multiple layers (typically 4 or 6) of spiral high-tensile steel wire.

Wires are laid in alternating directions (left and right hand) for flexibility and strength.

Common Types:

SAE 100R9, R12, R13, R15

R13 & R15 are among the highest pressure-rated hoses.

Pressure Rating:

Can exceed 6,000 psi depending on the type and size.

Maintains high-pressure performance even in large bore sizes.

Temperature Range:

Typically -40°C to +121°C (-40°F to +250°F), depending on the cover material and fluid type.

Applications:

Heavy machinery, mining, construction, offshore drilling rigs, and hydraulic systems with shock loads or pressure spikes.
