| Connection | Threaded |
| Working pressure | 16 bar |
| Hydraulic test pressure | 24 bar |
| Temperature | -10°C to 100°C |
| Standards | BS5154 |
| Applications | Pump protection, HVAC, plumbing and general service |
| Benefits | Debris protection, backflow prevention, extended system life |
Flexible connectors
Flexible pipe joints and couplings for vibration control and movement compensation
Flexible connector benefits
| Function | Absorb vibration, thermal movement and pipe stress |
|---|---|
| Use cases | Pumps, HVAC systems, building water and gas lines |
| Advantages | Improves piping reliability and reduces leaks |
| Material | High-strength elastomer and reinforcement |
| Design | Compact coupling with flexible resilience |
| Benefits | Better service life, quieter piping, easier maintenance |
Banff flexible connectors are a natural extension of the valve product line, offering corrosion-resistant joints that stabilize pressure lines and absorb vibration in dynamic building systems.
They are ideal for installations where pipe movement, pump cycling or thermal expansion can otherwise cause stress, noise and premature fitting failure.
