GEBO pump half-union 1 x 1½ set model 351-6S

GEBO pump half-union set 351-6S provides a detachable threaded connection solution for pumps with mixed port sizes of 1" and 1½". The kit is designed to join a pump outlet or inlet with corresponding piping using matched half-union components, enabling straightforward assembly and disassembly without cutting pipes or disturbing sealed joints. This model is intended for use in water and heating circulation systems where reliable, serviceable threaded connections are required.

Advantages

The GEBO half-union set enables fast removal and replacement of a pump without the need to dismantle sections of the pipeline. Its matched components ensure a secure threaded interface and reduce the risk of leaks when correctly installed. The kit simplifies maintenance tasks, shortens downtime during pump servicing, and preserves existing pipework by providing a reusable detachable connection between differing thread sizes.

Suitable for

• Replacement or upgrade of circulation pumps in heating systems
• Maintenance of water circulation pumps in domestic and commercial installations
• Situations requiring frequent pump removal for inspection or service
• Connecting pumps where one port is 1" and the other is 1½" threaded

Key specifications

• Connection type: half-union threaded connection set for mixed thread sizes
• Thread sizes accommodated: 1" and 1½"
• Application: water and heating circulation pump connections
• Function: detachable/reusable connection for easy pump removal
• Material characteristics: corrosion-resistant components suitable for plumbing environments

How to use

Ensure the pump and pipe threads are clean and undamaged before assembly. Position the half-union components on the corresponding pump port and mating pipe thread, then hand-tighten to align the threads. Use appropriate tools to finish tightening to the manufacturer's recommended torque for the piping material in use, taking care not to over-tighten. Verify the connection for leaks after restoring system pressure and follow normal commissioning procedures for water or heating systems.

Usage recommendations

Use compatible sealing materials where required by the installation (e.g., PTFE tape or approved thread sealant) and observe system operating temperature and pressure limits. For recurring maintenance, mark the orientation of components during initial installation to speed up future disassembly and reassembly. If uncertain about thread condition or compatibility, inspect or replace damaged threads to ensure a reliable seal.
