100-115mm Flexible Drain Coupling

Product Description

Streamline your drainage repairs or new installations with the 100-115mm Flexible Drain Coupling—a flexible, reliable solution designed to join or seal pipes with slightly varying diameters. Whether you need to repair damaged pipework, connect plain-ended pipes, or adapt in an area where pipe tolerances vary, this coupling offers a robust, watertight connection with minimal fuss.

This coupling is made with a sleeve of EPDM rubber, known for its excellent resistance to weather, temperature variation, and typical underground corrosion. It features stainless steel bands (Grade 304) on either end that clamp securely around the pipes. The coupling covers an outside diameter (OD) range of 100mm to 115mm, allowing for slight differences in pipe size—useful when matching old plastic or clay pipes, or when exact dimensions are unknown. It has a length of 135mm, width ~100mm, and depth ~135mm, making it compact enough to fit in tight spaces yet long enough to form a strong, reliable joint.

Designed for unadopted (private) drainage systems, this Flexseal coupling provides an airtight and watertight connection that can accommodate plain-ended pipes. It’s also suitable for repairing or replacing short sections of pipe. Installation is relatively simple: slide the EPDM sleeve over the pipe ends, align, clamp with the stainless-steel bands (torque of approx. 6 Nm), and you’re good to go.

Key Features

• Flexible OD range: 100–115mm to accommodate variation in pipe sizes.

• Material: EPDM rubber sleeve and Grade 304 stainless steel bands for durability and resistance to corrosion.

• Dimensions: around 135mm in length; width/depth approx 100-135mm depending on pipe alignment.

• Pressure & temperature resilience: can handle typical drainage pressures; resistant to effects of temperature fluctuations.

Benefits

• Versatility in repair & connection: Fits a range of pipe diameters, reducing the need for exact matching and making onsite adjustments easier.

• Leak prevention: The EPDM sleeve plus stainless clamps form a secure, watertight, and airtight seal—helps avoid infiltration of ground water, leakage, or misalignments.

• Durable & resilient: Built to endure underground environments—moisture, soil movement, seasonal thermal expansion. Materials are chosen for longevity.

• Saves time and cost: Repairs using a coupling are faster, simpler, and cheaper than replacing full pipe sections or trenching where coupling joints can be used.

• Safe for private systems: Suitable for unadopted pipe work; useful in domestic, farm, small commercial sites where regulatory constraints differ.
