Always provide some angle on straight hose installations, this reduces forces and ensures that hose is only bending i one direction. The Hose must have some slack to compensate for hose length variations.

When radius is below the required minimum, use an angle adaptor to avoid sharp bends.
At radius below required minimum, angle adapters should be used to prevent sharp hose bends.

To prevent hose collapse and flow restriction, hose bend radii should be kept as large as possible. Tight bends can also compromise the hose reinforcement and cause premature hose failure. Refer to hose specification table on page 6 for minimum bend radii.
