Important factors for identifying hose length
- Jan 22, 2018 -
Whether you are identifying hose lengths by OAL or hose cut length, remember that length will change under pressure through expansion or contraction (typically between 2% to 4%). Other important factors to consider include:
Make note of machine vibration and motion, as well as the routing design.
Allow enough length so that the fittings are not subjected to pull-off forces when parts reach their limits of travel.
Avoid stretching the hoses, as this can restrict fluid flow.
Avoid clamping hoses at their bends, to allow for length changes during pressurization.
Do not clamp high and low pressure lines together.
Cut the new hose the same length as the one being removed when replacing hoses.
