Play safe with hydraulic hose

Whilst commercial considerations encourage the re-ending of hydraulic hoses, it is in effect an illegal practice in Europe and the wider world and is contrary to BS EN 982 'Safety of Machinery - Safety requirements for fluid power systems and components - Hydraulics' here in the UK as well. Ian Morris of the BFPA says: "Whilst a re-ended hose may look perfectly good and pass a pressure test, there are a number of critical factors which must be taken into account. The first issue is degradation. All hoses degrade over time. Chemical changes in the hose compound mean that cutting and inserting a new end can alter the molecular structure further rendering it weaker than it should be. The angle of any internal reinforcement can also change to the detriment of the hose integrity when a new end is inserted. Another critical issue is hose length. Cutting a hose will reduce its length to below that installed by the original manufacturer with the result that it can be over stressed when refitted." The BFPA itself doesn't gain financially by alerting the industry to the illegal practice of re-ending hoses, instead it gains as do all members of the BFPA by raising standards within the industry as a whole and creating a 'best practice' ethos within those who work in the industry. The BFPA operates a 'Q' Approved Hose Assemblies scheme which seeks to ensure that only approved hoses are fitted throughout the industry.
