Common Application Terms

As application experts, we have listed some common industry terminology to help you determine the right product for your specific application.

BEND RADIUS DEFINITIONS

Bend radius (silicone hose and all rubber hose)

The radius of a bent section of hose measured to the innermost surface of the curved portion.

Minimum bend radius

The smallest radius at which a hose can be used.
Dynamic bend radius The radius at which constant or continuous flexing occurs.

Static bend radius

The smallest fixed radius at which a hose can be subjected.

Force to bend
The amount of stress required to induce bending around a specified radius. Hence, a measure of stiffness.

Bend Radius (all, except metal hose) = R1

PRESSURE DEFINITIONS

Maximum rated working pressure
The maximum pressure that the hose should be subjected
to on a continuous basis.

Nominal rated burst pressure
The average pressure at which the core or braid will rupture at ambient temperature. This is usually tested at 68"F.

Pulsating or shock pressure
The performance of hose can be greatly reduced under pulsating working pressure. Pressures are normally reduced by 50% in pulsating or shock pressure applications.

Pressure/temperature correction
Silicone and rubber hose pressure capabilities decrease as the temperature increases.

Pressure drop
The measure of pressure reduction or loss over a specific length of hose.
