1/2 Inch Malleable Iron Pipe Coupling - Galvanized Threaded Fitting

Yes, the sleeve has UBA METALLE approval and can therefore be used for drinking water installations.

Yes, this temper cast socket is approved for gas installations. It has the necessary DVGW approval for this application area.

Yes, the 1/2 inch socket is designed for the transmission of gases like compressed air. It withstands an operating pressure of 25 bar at temperatures up to 120°C.

Yes, the sleeve is designed for temperatures up to 300°C. At 150°C, the maximum allowable operating pressure is 20 bar.

The cylindrical internal threads are not self-sealing by default. Therefore, the use of a suitable thread sealing material such as PTFE tape or hemp is mandatory.

The coupling is made of malleable cast iron and has a tensile strength of under 350 N/mm², which ensures high stability. It is designed for industrial use and withstands the usual tightening forces.

The sleeve is galvanized, providing effective corrosion protection. For normal outdoor use, no additional rust protection treatment is required.

Yes, malleable iron fittings like this sleeve are explicitly mentioned in the description as suitable for sprinkler and gas extinguishing systems.

The threaded connections of this coupling are not self-sealing. You must seal them with suitable material such as Teflon tape or hemp.

The UBA METALLE approval is important for use in drinking water installations. It confirms that the material meets the hygienic requirements and does not release harmful substances.

Yes, the coupling is designed for high temperatures. It can carry liquids and gases up to 300°C at a maximum operating pressure of 20 bar.

Yes, this coupling is suitable for heating systems. It withstands temperatures from -20°C to 120°C at 25 bar and up to 300°C at 20 bar.

Yes, the sleeve is galvanized and suitable for outdoor use, for example on a rain pipe. This protects against corrosion.

For sealing threaded connections, you can use both Teflon tape (PTFE thread seal tape) and thread seal hemp. The threads are not self-sealing.

The coupling has a 1/4 inch Whitworth pipe thread (internal thread). Check if the connections of your garden hose and irrigation computer match this thread type.

Yes, the temper cast sleeve is suitable for use at temperatures down to -20°C. Therefore, it can be installed without problems in refrigeration systems.

Yes, the coupling is designed for a maximum allowable operating pressure of 25 bar at temperatures from -20°C to 120°C. In cold water installations, it withstands this pressure.

Yes, the sleeve is suitable for temperatures from -20 °C to +200 °C. It also withstands a working pressure of up to 10 bar.

The sleeve has a Whitworth pipe thread according to common standards (ISO 7-1/EN 10226-1). Check the thread type of your old pipes for compatibility.

Yes, the threads of the sleeve allow for a seamless transition to other materials. A special transition fitting is not needed for this.

Yes, you need additional suitable sealing material to seal the threads. Hemp or Teflon tape are suitable for this purpose.

Yes, the coupling is made of stainless and corrosion-resistant steel 316 (V4A). It can be used permanently outdoors.

Yes, the sleeve is made of stainless steel 316 (V4A), which is highly corrosion-resistant and suitable for use with chlorinated water.

The sleeve is made of stainless steel 316 (V4A), which offers high corrosion resistance. It is therefore also suitable for saltwater applications.

Yes, the stainless steel sleeve is designed for hot water and temperatures from -20 °C to +200 °C. Use in heating systems is therefore possible.

Yes, the stainless steel threaded fittings are designed so that, unlike welded or press fittings, they can be loosened again at any time.

Yes, the stainless steel sleeve 316 (V4A) is suitable for drinking water installations. It is rust-free and durable.

Yes, the stainless steel 316 coupling is rust-free and corrosion-resistant. Its temperature range is from -20 °C to +200 °C, allowing it to be used even in frost.

The coupling is designed for a working pressure of up to 10 bar. If the pressure in your compressed air line does not exceed this value, use is possible.

Yes, due to the material stainless steel 316 (V4A), the coupling is rust-free, corrosion-resistant, and durable. This makes it ideal for permanent use in the ground.
