When hose installation is straight, allow enough stack in hose line to provide for lenght changes which will occur when preesure is applied.
When radius is below the requirement minimum, use an angle adapter to avoid sharp bends.
Adequate hose length is necessary to distribute movement on flexing application and to avoid abrasion.
Use proper angle adapter to avoid tight or bend in hose.
Avoid twisting of hose lines bend in two planes by clamping hose at change of plane.
Prevent twisting and distortion by bending hose in same plane as the mation of the part to which hose is connected.
Reduce number of pipe thread joints by using hydraulic adapters instead of pipe fittings.
Route hose directly by using 45o and/or 90o adapters and fittings. Avoid excessive hose length to improve appearance.
When installing hose, make sure it is not twisted. Pressure applied to a twisted hose can result in hose failure or loosening of connections.
To allow for length changes when hose is pressure, do not clamp at bends so that curves will absord changes. Do not clamp high and low pressure in lines together.
