With almost 200 years of experience, GF's white malleable cast iron continues to enjoy great popularity and is known worldwide for its outstanding quality.

Both the classic malleable cast iron fitting and the Primofit compression fittings are an integral part of systems for liquids and gases installed worldwide. Both products have been reliable companions of installers worldwide for many years and are highly valued for their high quality.

Fittings and compression connectors for various applications in the field of gases and liquids. Both fittings and Primofit are pressure-tested in accordance with current standards. Details can be found in the catalogs linked on the website.

Pipe couplings DVK-HD® high pressure
DVK-HD® pipe couplings are ideal for use in pressure conveyors. These couplings have the following characteristics:

• no welding necessary – therefore safe and without danger
• easily to be dismantled – connecting pieces and pipes can be reused
• with stainless steel grounding strip to ensure electrical conductivity
• not suitable for liquids

We can deliver DVK-HD® pipe couplings for all common diametres from 60.3 mm to 206.0 mm – anodized version at request.
Mounting instructions for DVK-HD® pipe coupling
When mounting pipes with our DVK-HD® pipe couplings, it is important to ensure that the pipe coupling is protected against shifting by means of suitable pipe clamps / wall brackets or mounts (made by Hilti or Müpro).
The pipe coupling can seal the pipe up to the specified pressure, but cannot protect it against movement or shifting.
All DVK-HD® couplings are suitable for pneumatic or vacuum transportation (not for liquids!).
DVK-HD® couplings are supplied ready for assembly.
Important – please note:
1. Mark the clean ends of the pipe at half of the length of the pipe coupling. Make sure that the gasket shafts interlock and do not overlap!
2. Now shift the coupling over the pipe as far as the marking (free of dirt and oil). Then shift the next pipe through the coupling until the two ends abut together.
3. Tighten the screws evenly to 80 Nm. The pipe coupling / gasket will only stand up to the pressure indicated if it is correctly assembled.
4. Observe the following value: Tightening torque for all DVK-HD® couplings 80 Nm.
5. We shall be pleased to answer any technical questions you may have.

Pressure hose connectors Connect pressure hose to equipment for pressure measurement. It is available in a variety of types, such as threaded connection, quick insert, etc., to adapt to different pipe diameters and interface specifications. Material selection of stainless steel, copper alloy, corrosion resistance and durable. Convenient installation, good sealing performance, can accurately transmit pressure signals, ensure accurate and reliable pressure measurement, widely used in industrial, hydraulic system and other pressure measurement scenarios. customizable

In industrial production, mechanical equipment and all kinds of engineering systems, the pressure gauge connection plays a crucial role. Through suitable fittings and fittings, the pressure gauge is connected to pipes, containers and other equipment, so that the internal pressure is accurately measured and monitored in real time. For example, in the steam boiler system, the pressure gauge is installed in the boiler body through a reliable connection, and the operator can grasp the internal pressure at any time to ensure the safe operation of the equipment; In the hydraulic system, the connection of the pressure gauge can directly reflect the pressure condition of the hydraulic oil, which is easy to debug and troubleshooting. The precise connection application of the pressure gauge provides strong support for the stable, safe and efficient operation of the system.
