S	 NASA TECH BRIEF 
This NASA Tech Brief is issued by the Technology Utilization Division to acquaint 
industry with the technical content of an innovation derived from the space program. 
Safety Restrainer Prevents Whipping of Ruptured High-Pressure Hose 
The problem: Failure amounting to rupture in fluid 
transfer hoses under high pressure can cause whipping 
action damaging to equipment and dangerous to per-
sonnel. 
The solution: A modification of a standard electric 
cable puller reinforces high-pressure, flexible, fluid-
transfer hoses and restrains them if a failure occurs. 
How it's done: The braid at each end of a standard 
electric-cable puller is modified to the form of a dou-
ble cable loop. The modified cable puller is installed 
over the high-pressure hose and the two loops are 
secured to some structural member at each end of the 
hose, for example, a fuel trailer frame member or a 
fluid manifold support structure member. If a failure 
occurs in the hose, it is safely restrained while correc-
tive action is taken.
Notes: 
I. This device provides a strong anchoring method 
that securely restrains even a completely severed 
hose under very high pressure.
