Q:
Please share with us any “non-standard” applications that hose fittings have been used for.
14 answers
Answers:
Most non-standard applications have been mis-applications where the wrong fitting has been selected for the wrong application, (example) cam and groove fittings used as the connection in a freon 11 transfer/loading operation, (example) Chicago style fittings being used for steam service.
~Steve M, Marketing/Sales, Bakersfield, CA
In an emergency temp state of mind, we have used hydraulic hose in water of coolant systems. I am sure that isn't all but that is all I can recall at the moment.

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of hose fittings?
22 answers
Answers:
Under tightening is the number 1 failure of fittings and costs millions of dollars a year in leaks.
~Michael A, Process Engineer, Chaska, MN
There have been instances of Chicago fittings being used for steam service in place of traditional ground joint fittings typically used for steam service. Chicago fittings are designed for air service, connect with a 1/2 turn, seal with matching rubber gaskets in each fitting, the fittings are not for steam service and the gaskets are compounded for high temperatures. These fittings are easily unintentionally disconnected during routine steam service which leads to a whipping and burn hazard, and resultant serious injury and fatalities.
~Steve M, Marketing/Sales, Bakersfield, CA
It is CRITICAL that port specifications on all hydraulic components be listed on the drawing! I know of a case where a steering motor with straight thread O-ring ports... thread size was called out, but not the port spec that designated how to make the O-ring groove up by the spotface/counterbore. The wrong adapters were easy to install and torque up, but they soon leaked. NOT GOOD ON A STEERING MOTOR.
~Design Engineer, Jackson, MN
Yes, and costly. The hoses were not installed correctly during maintenance and cause a huge dump truck to catch on fire, causing over $500,000 worth of damage in a remote part of China.
~Keith M, Manufacturer, Columbus, OH
Where do I begin? How about plumbing a simple constant driven gear pump into a closed center control block! Installing a 2000 psi hose in a 3000 psi system twice in a row. Because that was all that was on hand the first time! Oh the second failure was. " I replaced it with the same hose that came off"! Or the best one was finding the hose was not inserted all the way into the collar before being pressed.
~Bill T, Fleet Manager, Lakewood, WA
Not end fittings, but because 9 was not followed I have had to supply very expensive SPECIALS when contact earlier would have resulted in cost effective standard products being used.
~Ray S, Marketing/Sales, Swindon, England
Using a plated steel fitting instead of Stainless Steel. The fluid was slightly corrosive, and over time, compromised the integrity of the fitting.
~Rick F, Production Engineer, NEWARK, CA
Nearly destroyed an engine and turbo due to cheap Chinese fittings. Incorrect drainage size fittings.
~Peter Saunders, Home mechanic, Adelaide, Australia
Wrong thread configurations can cause users to strip or damage equipment and cause huge leaks...
~RICHIE M, Marketing/Sales, Kaukauna, WI
Blow the fittings off from too much pressure / eaten by corrosive materials.
~Leonard H, Facilities Manager, Fresno, CA
Most common, using fittings not designed to take pressure.
~Bob G, Technical Support, Brisbane, Australia
System failure because fittings were not rated high enough.
~Chris J., Builder/Contractor, Edmonton, Canada
Yes, blown hoses; environmental contamination.
