The MannTek SBC Industrial Breakaway Coupling (1" BSP Female x Female) is a safety-critical solution designed to protect fuel transfer systems, hose assemblies and loading arms from damage and spillage caused by drive-away or pull-away incidents. Manufactured in stainless steel with Viton® seals, this unit is ideal for demanding fuel, chemical and industrial fluid handling applications.
Engineered as the weakest link in the transfer line, the coupling separates at a defined tensile load and instantly seals both ends, minimising product loss and environmental risk. The SBC Industrial version uses a breaking bolt design, allowing controlled release under excessive load conditions while maintaining system integrity during normal operation.
Key Features:
- 1" BSP female parallel threads both ends
- SBC Industrial breaking bolt design with three external stainless steel bolts
- Stainless steel construction (AISI 316 / 316L equivalent) for corrosion resistance
- Viton® (FKM/FPM) O-rings for compatibility with fuels and chemicals
- PTFE flat seals for BSP parallel thread connections
- Integrated shut-off valves – seals both ends upon separation
- Activation by tensile load (pull) at angles up to 90°
- Rebuildable on site using spare parts
Typical Applications:
- Fuel transfer and tanker loading/unloading (road and rail)
- Bulk liquid and container discharge systems
- Terminal, depot and industrial transfer installations
- Petroleum, chemical and compatible fluid handling
Installation & Compatibility:
- Installed between hose assembly or loading arm and a fixed connection point
- Compatible with BSP threaded systems
- SBC range available in sizes from 1" (DN25) up to 12" (DN300)
- Alternative connections available across the range including BSP/NPT threads and DIN/ANSI/TW/TTMA flanges (others on request)
