Hydraulic hose failures lead to costly downtime, fluid spills, and safety hazards. Failure modes are a good thing to know about so you can have more?

Vector Hose Common Problems And Solutions.

Cause 1: Cracking of the tube - usually associated with fluid compatibility or severe temperature cycling.

Solution: Upgrade to PTFE Hose or Thermoplastic Hose.

Cause 2: Cover Abrasion - Hoses rubbing against machine frames.

Answer: use Heavy Duty Hose with UHMwPE Cover or with protective sleeving.

Cause 3: Blistering - result of gas permeability or rapid decompression.

Solution: select MSHA Hose or pin-pricked covers in gas service.

Cause 4: Burst at fitting – due to improper Hydraulic Hose Crimping or Hose Coupling which is not compatible with the hose.

Solution: how to properly match ferrule to hose and crimp spec.

Cause 5: Kinking – bending beyond radius minimum.

Solution: for tight spaces, use the compact R16 or R17 hose options.

Vector Hose recommends periodic visual examinations check for signs of cracking, bulging, leaks or corrosion. Change the hoses every 5-7 years or then after a major jolt of a shock event. Trim off the end with a Hose Cutter for nice clean ends when making repairs. For high-impulse applications such as excavators, go with 4SP or 4SH spiral hoses. For fuel lines, NBR Fuel Hose is oil resistant. Technical bulletins and training are available through Vector Hose.
