The Importance of Impulse Testing for High Pressure Hydraulic Hoses

2026-08-06

Hydraulic hose products aren't all made equal. Durability is really tested by impulse cycling – mimicking real-world pressure pulses. On every lot of our High Pressure Hose Vector Hose makes a standard Impulse test.

Why should that matter?

Thousands of pressure surges in a hydraulic system. A hose with a burst rating suitable for a static test may fail prematurely under dynamic impulse.

Our 4SP, 4SH, R12, R13 and R15 hoses are tested to the highest standard SAE and DIN have to offer. Vector Hose also tests Rubber Hydraulic Hose for Oil Resistance, Cold Flexibility, and Ozone Aging. Impulse testing ensures that the layers of reinforcement (braided or spiral) remain cohesive when flexed and pressurized many times.

For Drilling Hose in oilfield applications, the API 7K impulse demands are even higher. Our Rotary Hose and Mud Hose are tested for high frequency pulses. Certification documents are available to Vector Hose customers upon request.

When purchasing a High Pressure Flexible Hose, such as this one, be sure to ask if impulses data is available. Inexpensive hoses often omit this step and fail in the field. We make the necessary investments in testing apparatus, so you can be confident you are getting dependable, long-life products.

If you're shopping for Hydraulic Hose Pipe for your press or Water Hose for your pressure washer, you'll find that impulse-tested designs will reduce your overall cost of ownership.
