Useful Information
What is a Drain Coupling Used For?
Fernco Drain Couplings, also known as Flexseal couplers, are efficient and straightforward connectors used primarily in unadopted or private drainage systems. They are designed to connect two pipes with the same or similar (within 10mm) outside diameter, making them ideal for connecting plain-ended pipes or for repairing existing pipe systems by replacing short sections of pipe.
Key Features
- Ease of Installation: Notable for their simple fitting process, these couplings can be easily installed without specialized skills.
- Versatility: Suitable for a variety of applications, including housing sites, private roads, and agricultural lands.
- Airtight and Watertight Seal: Once installed, they provide a completely airtight and watertight connection, ensuring the integrity of the drainage system.
- Durable Material: Made from a moulded EPDM rubber body and stainless steel clamp bands, offering robustness and longevity.
- Cost-Effective Solution: Provides an inexpensive yet reliable option for connecting unadopted drainage pipes.
Specifications
- Size Range: Available in sizes from 40mm to 275mm, catering to a wide range of pipe diameters.
- Material Composition: EPDM Rubber and 1.4301 (304) Stainless Steel for enhanced durability.
- Temperature Range: Suitable for temperatures from -50°C to 80°C continuously, and up to 100°C intermittently.
- Jetting Resistance: Can withstand jetting pressures up to 180 bar.
- Pressure Rating: Rated for 0.6 bar (8.70 psi).
- Standards Compliance: Meets BS EN 681-1:1996, BS EN 295-4:2013, and BS EN 10088-2:1995 standards.

How and Where to Install
The Fernco Drain Coupling is straightforward to install:
- Positioning: Align the coupling over the ends of the two pipes to be connected.
- Securing: Use a nut driver and torque wrench to tighten the stainless steel clamp bands around the pipes.
- Checking: Ensure a snug fit to create an effective airtight and watertight seal.
Note on Usage: While Fernco Drain Couplings are ideal for unadopted drainage systems, they are not suitable for adopted drainage systems managed by highway agencies, water companies, or local authorities. In these cases, Fernco’s Shear Banded Couplings should be used as per WIS 4-41-01 specifications.
