WaterArmor Protective Equipment

High-Pressure Water Jet Testing Results Proves TurtleSkin WaterArmor Protection

Protects Up To 40K psi
TurtleSkin WaterArmor uses an innovative, patented fabric to provide protection from high-pressure water jet injuries.

Created by Warwick Mills, TurtleSkin is made from the tightest weave ever achieved in aramid, a fiber two times stronger and five times lighter than steel.

TurtleSkin WaterArmor can protect ultra high-pressure water jet operators from pressures as high as 2800 bar (40,000 psi).

High Pressure Water Jetting Testing

Certified Water Jet Protection
We certify all TurtleSkin high-pressure water jet protective products to meet specific performance standards. We ensure that the quality and calibration levels of all of our high-pressure water jet safety equipment. Warwick Mills is ISO-9001:2008 Certified.

The protective performance of TurtleSkin WaterArmor depends on multiple factors, such as pressure, water flow, nozzle diameter and construction, distance between the high-pressure water jet and protective equipment, and contact time (swipe speed of the water jet). Under extreme circumstances (high pressure, high flow, close distance, and low speed) WaterArmor may not provide full protection. Please review the chart below.

High-Pressure Water Jet Testing Results:

The following conditions did not result in penetration of the protective system with high-pressure water traveling at 8 feet/second (2.4 meters/second) at no closer than 3 inches (7.62 cm):
