Sievert Hose Failure Valve - UTTK9387

This regulator is designed specifically for flammable gases, such as propane, due to its P.O.L. fitting.

The hose failure valve is a safety feature that automatically stops the flow of gas if it detects a significant and sudden drop in pressure, typically caused by a damaged or severed hose.

P.O.L. stands for Prest-o-Lite. It is a standard fitting used exclusively for flammable gases, featuring a left-handed thread for connection to gas cylinders.

No, this regulator is not suitable for natural gas. It is designed only for flammable gases with a P.O.L. fitting.

The outlet size is 3/8 inch, which is a common size for gas hoses.

It is recommended to check for leaks every time you connect the regulator to a gas cylinder and periodically during use.

Typically, dispatch occurs within 2 working days, with delivery usually completed in 3-5 working days within the UK mainland.

Ensure the gas cylinder valve is fully open. Check that the regulator is securely connected to the cylinder. Verify the hose and any connected appliance are not blocked.

Turn off the gas supply immediately. Re-seat the regulator connection to the cylinder, ensuring a tight fit. If leaks persist, the O-ring or fitting may be damaged; discontinue use and replace the regulator.

Check for kinks or damage in the connected hose. Ensure the gas cylinder has sufficient pressure. The hose failure valve may have engaged due to a sudden pressure drop; reset by closing and reopening the cylinder valve slowly.

Inspect the entire gas line for leaks. Ensure the appliance connected is not consuming gas at a rate exceeding the regulator's capacity. If the issue persists, the regulator may require servicing or replacement.
