1 1/2 Inch Galvanized Malleable Iron Pipe Fitting Coupling

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 sleeve's internal thread is parallel/cylindrical manufactured according to ISO 7-1/EN 10226-1 and fits tapered external threads according to the same standard. With a suitable sealing material, a reliable and tight connection for liquids is ensured.

Yes, the socket is DVGW-approved and thus suitable for gas installations. For sealing, you should use suitable thread sealing materials such as PTFE thread sealing tape or thread sealing hemp, as the connections are not self-sealing.

The internal threads of the socket are parallel/cylindrical. Tapered external threads are designed to seal in parallel cylindrical internal threads; cylindrical external threads also fit.

The threaded connections are not self-sealing and must be sealed. Use suitable thread sealant material such as Teflon tape or hemp.

For permanent use, suitable thread sealing materials such as PTFE thread sealing tape or thread sealing hemp are recommended. These materials ensure reliable sealing of non-self-sealing threaded connections.

Yes, the surface of the malleable iron fitting is galvanized. This provides protection against corrosion under normal usage conditions.

Yes, the sleeve is DVGW-approved and complies with UBA METALLE guidelines. It is suitable for conveying liquids such as drinking water.

The threaded connections of the fitting are not self-sealing. For sealing, you should use suitable material such as Teflon tape or hemp.

The coupling made of galvanized cast iron is robustly manufactured and intended for various applications, including mechanical engineering. Its tensile strength is < 350 N/mm², which means good resistance to mechanical stress.

For sealing the threads, the use of suitable thread sealing material is recommended, such as PTFE thread sealing tape or thread sealing hemp.

The coupling is designed for a maximum operating pressure of 25 bar at temperatures from -20°C to 120°C. At higher temperatures up to 300°C, the maximum allowable pressure is 20 bar.

A 1 1/2 inch coupling is designed for pipes with corresponding Whitworth pipe thread dimensions. A pipe with a 40 mm outer diameter does not match the standard size of a 1 1/2 inch pipe (approximately 47.8 mm outer diameter for a matching external thread).

The socket has parallel/cylindrical internal threads according to ISO 7-1/EN 10226-1. A tapered external thread will fit, sealing is done with suitable sealing material.

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

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 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, 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.
