Kérem válasszon terméket!

When filling gas cylinders with WEH® Connectors such as TW42, TW52, TW54, TW57, TW101, TW102 and TW152, the medium is often supplied to the connectors via hoses instead of pipes.

WEH® THP40 Hoses are made of Kevlar® reinforced PTFE and have a very high thermal degradation threshold and auto-ignition temperature due to their smooth bore finish. So even when the flow is at high pressure, there is only a low temperature rise. They are also resistant to a wide range of chemicals and solvents.

In addition, the pressure hoses offer excellent flexibility and bending tolerance, allowing the WEH ® Connector used to be quickly and easily connected to the gas cylinder. Vibrations are absorbed, which reduces noise and protects mounting points such as fittings.

The pressure hoses can be used for various demanding applications.

With the THP40 pressure hoses, WEH offers a complete product range: from the quick connector for connection to the gas cylinder to the hose for installation on the gas filling plant.
