Flexseal Couplings
Flexseal design and manufacture the most comprehensive range of fully approved low and non pressure flexible couplings in the marketplace. Flexseal couplings are suitable for sewerage, drainage, plumbing and vent systems, and can be used with plastic, clay, concrete, cast iron and steel pipes.

Features & Benefits:
- Durable design ensuring a high performance and reliable seal
- Stainless steel shear band provides excellent resistance to heavy loads and shear forces
- Reduces excavation work
- Complies with WIS 4-41-01 (all public sewers and sewers for adoption)
- Shear band ensures joint flexibility and pipe alignment
- High performance sealing properties of the couplings eliminates need for grouting in most applications
Applications:
- Flexseal Couplings have many applications in the construction, repair and maintenance of pipe systems:
- As a joint for plain ended pipes
- Repair and maintenance of existing pipelines
- Connecting short and cut lengths of pipe
- Making post construction connections to an existing pipeline
- Reconnection of laterals on renovated sewers
- Introducing rocker pipe outside manholes or structures
