Circle of Safety

Many industrial hose manufacturers will suggest which coupling to use with which hose for a given application, but they won't guarantee that combination will perform to the rated burst pressure of the hose.

Parker will.

Our Circle of Safety program establishes Parker's Industrial Hose Division as a single, accountable source with a specific performance guarantee to protect distributors and end users from accidents, unplanned downtime and increased liability associated with failed industrial hose assemblies.

In this age of litigation, where individuals and corporations are being sued on a daily basis for what seems to be only the slightest reason, what is your liability for industrial hose assemblies (non-hydraulic) made at your facility?

For over 50 years, there have been rigid standards for hydraulic hose assemblies.

The Society of Automotive Engineers (SAE) first established these hydraulic hose and fitting standards (SAE J517) in 1952. In 1968, testing standards (SAE J343) were established. This was done to ensure that hydraulic hose assemblies working under pressure in a hydraulic system would be safe and reliable and not a danger to workers or the environment.

On the other hand, industrial hose used to convey acids, chemicals, gasoline, abrasive materials, LP gas, solvents, welding gases and slurries can cause far more harm to workers and the environment if there is a failure. The hoses that are used to transport these hazardous materials have no established safety standards!

There are more than 200 manufacturers worldwide that make only industrial hose and do not manufacture any end-connections. There are dozens of end-connection (fitting) manufacturers that machine these components so they fit onto the hose, but have little or no knowledge of the compressibility, elasticity or flow of rubber compounds that have wire or fabric reinforcement. And there are clamp (attachment) manufacturers who have little knowledge of how much compression is needed to enable the rubber and reinforcement to hold the fitting under pressure. Then, when you consider the thousands of Distributors/Fabricators who make hose assemblies without any industry standards, it is not surprising that litigation for industrial hose is over 100 million dollars annually in the United States!

There are four critical components of an industrial hose assembly. Three of these components—the hose, fittings and clamps—must be designed to allow their differing tolerances to work together to ensure that a hose will fail before its fitting blows off. The fourth component is the distributor/fabricator of the hose assembly. Do you have a system to compensate for the plus and minus tolerances of all of the components? What type of clamps (attachments) are you using? Do you use worm gear, flat bands, 2-bolt, 4-bolt, swaged or crimped methods for holding the fittings in place? What testing do you use to validate the performance of the hose assemblies you fabricate? Is there a certified procedure and documentation for you to follow to fabricate safe, reliable hose assemblies? Can you, or your distributor, make up an industrial hose assembly with the same high level of confidence that has long been the standard for hydraulic hose applications? Do you have a vendor that will stand behind you with liability insurance coverage if there is a problem with an industrial hose assembly?

With the responsibility you have at your distributorship, what can you do to eliminate or substantially reduce your liability for industrial hose assemblies being fabricated by your company?

The “ Circle of Safety ” program from Parker's Industrial Hose Division could be the way to resolve these issues.
