Compression coupling GEBO QA 3/4" GZ for steel pipes, model 17.195.00.02

GEBO QA compression coupling 3/4" GZ (model 17.195.00.02) is a mechanical connector engineered for joining steel pipes with a 3/4-inch nominal diameter. The coupling employs a compression clamp principle to form a pressure-tight joint without welding or threading, enabling quick repairs, installations and extensions in plumbing and heating pipelines. Constructed for compatibility with standard steel pipe dimensions, this coupling provides a straightforward, tool-assisted connection method suitable for confined spaces and retrofit work.

Advantages

The compression coupling delivers a leak-resistant seal using a clamp and gasket system that does not require hot work or pipe end reworking. Installation is typically faster than welded or flanged connections and can be performed with common hand tools. The design minimizes on-site preparation and reduces system downtime during maintenance or modification. Its mechanical nature allows for disassembly or repositioning when needed, and the coupling is suitable for use in systems where controlled mechanical joining is preferred.

Suitable for

• Repairing damaged sections of steel pipelines in plumbing and heating systems
• Joining and extending steel pipe runs without welding
• Retrofit installations in confined or difficult-to-access locations
• Temporary or permanent mechanical connections where a sealed joint is required

Key specifications

• Nominal pipe size: 3/4 inch
• Connection principle: compression (clamp) with sealing gasket
• Material compatibility: steel pipes
• Suitable applications: plumbing, heating and general pipeline repair
• Installation: mechanical fastening with standard hand tools

How to use

Prepare the pipe ends by ensuring they are clean, free of rust flakes and burrs, and aligned with an appropriate gap if specified by the manufacturer. Slide the coupling body and gasket components over the pipe ends according to the coupling orientation, then position the pipes to the required insertion depth. Tighten the compression fastenings incrementally and evenly using recommended hand tools until the specified torque or compression is achieved and a secure seal is formed. After installation, inspect the joint for alignment and perform a pressure or leak test as appropriate for the system.

Usage recommendations

Use corrosion-protected or compatible pipe surfaces and ensure gasket materials are suitable for the system media and temperature range. Follow applicable plumbing and heating standards for pressure testing after installation. Where possible, use a calibrated torque tool to achieve consistent fastening and re-check connections after initial system pressurization.
