Flex Hose Installation Precautions

DO NOT TORQUE DURING INSTALLATION.

Metal hose assemblies should not be used to compensate for bolt hole misalignment. Floating flanges will help to minimize twisting of the metal hose. Pipe unions will help to reduce twisting during connection to the piping. The use of two wrenches will help to keep the hose from twisting when tighten the pipe union.

DO NOT COMPRESS OR EXTEND AXIALLY.

Corrugated metal hose installed in-line with the longitudinal axis of the piping should not be subject to axial movement.

DO NOT ALLOW HOSE MOVEMENT IN MULTIPLE PLANES.

Flexing a metal hose in two separate planes of movement will torque the hose assembly. Always install the metal hose assembly so that flexing occurs in one plane only and this is the same plane in which bending occurs.

AVOID SHARP BENDS.

Use elbows to avoid sharp bends near the end of the metal hose assembly.
