"More than Just an Internal Coupling"
INTRODUCING

Internal Pipe Coupling System, With An E-Xtensive Range Of Adaptors & Unique Twist Lock Watertight Fitment.
When a VIPSeal flexible coupling cant be placed on to a damaged pipe due to the pipe being encased in concrete/brick or the pipe has been damaged/cut off at the floor or wall leaving little for the coupling to be installed to the IN-X is the solution.
Designed to connect rainwater and wastewater pipelines using the internal surface, the IN-X internal pipe coupling system offers a strong, watertight connection and flexibility, due to its unique twist lock mechanism & range of options including spigots, sockets, transitions, reducers and end caps. Meaning a single IN-X unit can be used for a wide range of applications.

Key Benefits:
- Watertight connection to internal pipe dimensions of multi pipe materials, e.g plastic, clay, cast iron.
- Ideal for pipes sheared in concrete or concrete slabs where an external coupling cannot be used.
- Quick installation.
- Range offers multiple adaptations with its unique “twist lock” connectors.
- NO tools required.
- Able to re-use after initial installation.
- Suitable for both above and below ground applications.
- Smoother transition between pipe inverts.
- Tested to resistance of up to 2.5 bar internal pressure.
- Complies and tested to BS EN295-4:2013/ WIS 4-41-01/ BS EN1401-1:2019/ BS EN1451-1:2017/ BS EN681-1:1996
