The importance of a hoseguard® safety valve

HOSEGUARD® Safety Valve

A HOSEGUARD® provides simple, efficient protection should an air hose rupture or become disconnected.

The HOSEGUARD® is a safety device you install between the point of air supply (at the FRL outlet) and the air hose. This device is critical to preventing accidents. Don’t wait until it’s too late to act! Install this valve on all your flexible hoses today. This is a basic safety rule that applies to all industries. Read on to understand how this component works as part of a compressed air piping system.

Situation — Air hose breakage and hose whip

When a fitting breaks free of a pressurized flexible hose or when a pressurized flexible hose ruptures, the flow of compressed air can turn the hose into a wild, thrashing hazard. This is referred to as hose whip. This hazard will strike anyone or anything in its path and:

  • Injure nearby workers or bystanders
  • Damage production
  • Blow up dust from the floor
  • Disperse particles in the air

What follows is a demonstration of an air hose without a HOSEGUARD® Safety Valve when it breaks. Watch the video from start to finish to see how the same situation can be averted if a HOSEGUARD® has been installed on the faulty hose.

A HOSEGUARD® provides simple, efficient protection should an air hose rupture or become disconnected.

How the valve works

The valve is factory set and configured to allow free passage of airflow during normal use of an air tool. If air consumption exceeds the valve’s preset value, the internal piston immediately cuts off the compressed air supply. Once the problem is solved, a built-in bleed hole leaks a certain amount of airflow, automatically resetting the HOSEGUARD® Safety Valve.

This process means the HOSEGUARD® meets two standards for air hose use:

OSHA Standard 1926.302(b)(7)

“All flexible hoses exceeding 1/2 inch inside diameter shall have a safety device at the source of supply or branch line to reduce pressure in case of hose failure.”

ISO Standard 4414-11 (

“When failure of a hose assembly or plastic piping constitutes whiplash hazard, it shall be restrained or shielded by suitable means and/or an air fuse for compressed air shall be mounted.”
