Propane Hoses are available in different lengths, diameters and connection types:

Lengths: 1.5 – 20 meters (4,92 - 65,6 foot)
Rolls: 50 meters (164 foot)
Diameters: 4 – 8 mm (0,16 - 0,31 inches)
Connection Types: Fixed and Swivel

A fixed connection stays in one position and doesn’t rotate, while a swivel connection can rotate, preventing the hose from twisting and improving flexibility during use.

EN ISO 3821 and SS-EN 16436-1:2014+A3:2020

A fixed connection stays in one position and doesn’t rotate, while a swivel connection can rotate, preventing the hose from twisting and improving flexibility during use.

Certain torch handles such as the Promatic has an integrated swivel hose connection.

Up to 30 bar (435 PSI).

Propane hoses include three layers for maximum protection and safety.

Inner layer: Gas resistant rubber. 
Middle layer: Reinforced synthetic fibers to withstand high pressure. 
Outer layer: Rubber to protect against outer damage, sunlight and ozone.

They can withstand and operate in temperatures down to -30º Celsius (22º Fahrenheit).

1. Check the connection of your torch system handle and choose a propane hose that has the same connection.
2. Check the connection of your pressure regulation device. Sievert pressure regulation devices have a BSP 3/8” LH propane hose connection.
3. Check your local regulations. There might be regulations / restrictions in terms of the which standard they should be manufactured to, length and diameters.

Check your Propane Hose for outer damage and leaks before use, no matter how new or old it is. As soon you discover there is outer damage or leaks, you should replace it immediately.

If there is no damage on your propane hose, check the manufacturing date that is printed on the Propane Hose. Usually, a propane hose should be replaced every 5-10 years if it isn’t damaged.

However, in certain applications where there might be more wear and tear on equipment than usual, our recommendation is that you replace your propane hose every 2 years.

If your local retailer is only selling rolls, they should also be carrying a variety of propane hose nipple assortment. Sievert offers different types of propane hose nipples.

While we can’t answer any detailed questions about other brands, our propane hoses are made of three protective layers for maximum safety and can withstand up to 30 bar (435 PSI) in pressure and operate down to -30º Celsius (22º Fahrenheit).

Perform a visual check for any cracks, wear or damage along the hose and connection points.

To perform a leak test, follow the simple steps below. Never use an open flame to check for leaks and make sure to perform the test outdoors or in well ventilated areas.

• Mix dish soap and water (50/50) in a spray bottle or bowl. You can also use a commercial leak detection solution.
• Turn on the propane cylinder slightly without lighting the torch system.
• Spray or brush the solution along the propane hose, connections and fittings.
• If you see bubbles forming it indicates there is a leak, and you should proceed to replace the propane hose immediately.
