Whipchecks- Air Hose Restraint-3/8” wire rope for hose i.d 4 Inch (Set 1)

Whipcheks® are designed for use on air hose at pressures of 200 PSI or less. Hydraulic oil is non-compressible and therefore does not induce hose whip during a coupling or hose failure. The real danger in these cases is high pressure oil being injected into a worker’s skin or eyes. The only suitable safety device for these applications is a solid guard between operators and connections.

 Whipchecks are not made in Stainless Steel because the increase in price is much higher than the increase in longevity. Stainless steel is not really stainless, and our Whipcheks® are already made of corrosion resistant parts. It is more economical to replace 3 standard Whipcheks® than one made of stainless steel. Second, stainless steel is about 15% weaker than equivalent diameter galvanized aircraft cable. Our design and the inherent 5 to 1 safety margin are based on the tensile strength of the cable we use. We’re not going to build a weaker product!

Whipcheks® are designed with a 5 to 1 safety margin at 200 PSI. At 300 PSI that margin drops to 3 to 1.  Any pressure above that is not a suitable application for Whipcheks® and may result in injury or death in the event of an explosive coupling decompression. We recommend Whipcheks® be used only on air hoses carrying 200PSI or less. Any other use is at your own risk.
