Coupling union GEBO 331-6S flat 1" for water/gas pipelines

Coupling union GEBO 331-6S flat 1" is a compact mechanical connector intended for joining two pipe ends in water and gas pipeline systems. The flat design reduces profile height, allowing installation in confined spaces and facilitating repair work where a 1" nominal connection is required. Constructed to provide a reliable seal between pipes, this coupling union is suitable for use in linear connections and short coupling spans in residential and light-commercial installations.

Advantages

The flat geometry of the GEBO 331-6S minimizes space requirements and permits installation in narrow cavities. Its mechanical design enables quick assembly without the need for extensive pipe modification, and the product is suitable for both water and gas pipelines when installed according to applicable standards. The coupling provides consistent sealing performance and simplifies replacement of damaged pipe sections.

Suitable for

• Connecting two 1" pipes in water supply lines
• Joining 1" gas pipes in low- and medium-pressure gas systems (subject to local regulations)
• Repairing damaged pipe runs where a low-profile coupling is needed
• Installations with limited installation depth or cramped access

When it may not be suitable

This coupling union is designed for 1" nominal pipe connections and may not be suitable for other diameters or nonstandard pipe geometries. It is intended for mechanical joining in typical water and gas applications; specialized systems with unusual pressure ratings, aggressive media, or requirements for welding or solvent bonding may require other connection methods or materials.

Key specifications

• Nominal size: 1"
• Design: flat/low-profile coupling union
• Application: water and gas pipeline connections
• Connection type: mechanical coupling for joining pipe ends
• Typical use environment: indoor and protected outdoor installations

How to use

Prepare pipe ends by ensuring they are clean, deburred, and cut square. Position the coupling so each pipe end inserts fully into its respective side of the union. Follow manufacturer torque or fastening instructions where applicable to secure the mechanical connections and compress the sealing element. After assembly, perform pressure testing and leak checks according to local codes and best practices before placing the system into service.

What to consider before purchase

• Confirm the pipe material and wall thickness are compatible with a 1" mechanical coupling
• Verify suitability for water or gas use according to local regulations and installation standards
• Ensure available installation space accommodates the flat/low-profile design
• Check required sealing and testing procedures for your installation

Usage recommendations

Install and test the coupling in accordance with applicable plumbing and gas installation codes. Use appropriate personal protective equipment and perform pressure/leakage tests after assembly. For gas applications, confirm compliance with local certification and safety requirements before commissioning.
