Compression coupling GEBO QI GW 1/2" for steel pipes (model 17.195.01.01)

GEBO compression coupling QI GW 1/2" is a mechanical fitting engineered to join 1/2-inch steel pipes with a sealed compression connection. The coupling creates a strong, leak-resistant joint without the need for welding or brazing, making it suitable for installation and repair work in plumbing, heating and industrial piping systems. The design is compatible with standard 1/2" nominal steel pipe dimensions and provides a compact connection that preserves internal bore and flow characteristics.

Advantages

The compression coupling offers a quick and reliable method of joining steel pipes while avoiding hot-work methods. Its clamp-style connection produces a secure seal that resists vibration and moderate mechanical stress. Installation requires only basic hand tools and does not alter the metallurgical properties of the pipe ends. The compact form factor minimises space requirements and maintains consistent internal diameter for uninterrupted fluid flow.

Suitable for

• Plumbing repairs and new potable water lines compatible with steel pipe
• Heating systems, including radiators and distribution manifolds
• Industrial piping where mechanical, non-permanent connections are preferred
• Retrofit projects where welding is impractical or restricted

Key specifications

• Connection type: Compression (clamp) coupling for mechanical sealing
• Pipe compatibility: Steel pipes with 1/2" nominal diameter
• Material characteristics: Durable metal fitting designed for mechanical pipe joints
• Installation: Requires tightening of compression components to form a seal; no welding required
• Application environments: Suitable for plumbing, heating and general industrial piping systems

How to use

Prepare the pipe ends by ensuring they are clean, cut square and free from burrs or corrosion that could prevent a proper seal. Slide the coupling components onto the pipe ends as per the manufacturer's assembly orientation, align the pipes to ensure correct axial alignment, and engage the compression mechanism. Tighten the compression nuts or clamps evenly to the recommended torque using appropriate hand tools until the seal is established. After installation, inspect the joint and perform a pressure test or leak check according to system requirements.

Usage recommendations

Use the coupling only on compatible steel pipe sizes and in applications where a mechanical compression joint is appropriate. Follow system pressure and temperature limits applicable to steel piping and consult relevant standards or a qualified installer if in doubt. When installing in confined spaces, ensure safe access and correct torque application to avoid over-tightening or under-tightening the compression elements.
