IN-X Internal Pipe Coupling | VIPSeal Drainage Repair Solution
Internal Pipe Coupling: How IN-X Helps When External Pipe Access Is Difficult
An internal pipe coupling can make a difficult drainage repair much easier when contractors cannot reach the outside of the pipe.
In many cases, the damaged pipe sits inside a concrete slab, runs through a tight void, or sits behind other services. Because of this, a standard external coupling can turn a small repair into a much bigger job.
The VIPSeal IN-X Internal Coupling gives contractors another option.
Instead of sealing around the outside of the pipe, IN-X creates a watertight connection from the internal diameter. As a result, contractors can repair or connect pipework when excavation, breaking out, or full external access would add time, cost and disruption.
What is an internal pipe coupling?
An internal pipe coupling seals from inside the pipe rather than around the outside diameter.
This makes it useful when contractors cannot easily access the outside of the pipe. For example, if a pipe has sheared inside a concrete floor, digging out the surrounding area may not always be the quickest or cleanest option.
In this type of situation, IN-X allows the repair to take place internally. That means less mess, less disruption and a more practical repair method for awkward drainage jobs.
IN-X internal pipe coupling for drainage repairs
The VIPSeal IN-X Internal Coupling has been developed for drainage repair situations where access causes the main problem.
Typical applications include:
- Sheared or damaged pipework in concrete slabs
- Internal drainage repairs where external access is restricted
- Pipe repairs in tight or confined spaces
- Repairs where excavation needs to be reduced
- Connections made from the internal diameter of the pipe
- Domestic, commercial and below-ground drainage repair work
Because IN-X seals from the inside, it gives contractors a useful option when a traditional external coupling does not suit the job.
Internal pipe coupling with quick twist-lock installation
IN-X uses a simple twist-lock action to create the internal seal. Therefore, contractors do not need specialist tools to install it.
This helps keep the repair process straightforward. It also makes IN-X a useful product to carry for jobs where the full repair method may not become clear until the pipework has been exposed or inspected.
Alongside the coupling itself, the IN-X range also includes accessories such as spigots, sockets, plugs and related fittings. These additional parts give contractors more flexibility when dealing with different pipe repair situations.
Available IN-X sizes
The IN-X range covers several common drainage sizes, including:
- DN50
- DN75
- DN95
- DN110
- DN160
This size range gives merchants, distributors and contractors a practical internal coupling option for a variety of drainage repair jobs.
Pressure tested for confidence
Product performance matters, especially when a watertight pipe repair is needed.
VIPSeal has pressure tested the DN110 IN-X Internal Coupling to 2.5 bar. The range is also tested against relevant pipe and drainage product standards, giving contractors added confidence when using the system in drainage applications.
In short, IN-X does more than offer a quick repair. It also supports a reliable seal in difficult access situations.
For contractors working on drainage repairs, it is always worth considering the wider installation requirements and general drainage guidance before choosing the most suitable repair method.
Why choose an internal pipe coupling?
External flexible couplings still provide the right repair method for many jobs. However, they rely on clear access around the outside of the pipe.
When that access is not available, an internal pipe coupling can provide a much more practical solution.
The main benefits of IN-X include:
- Internal sealing where external access is difficult
- Fast twist-lock installation
- No specialist tools required
- Suitable for awkward drainage repairs
- Helps reduce excavation and disruption
- Available in common drainage sizes
- Supported by a wider range of IN-X accessories
For this reason, IN-X works well as part of a contractor’s drainage repair kit. It gives them another option when the job does not suit a standard external repair.
Part of the wider VIPSeal range
IN-X adds another practical repair option to that range. It does not replace every coupling, and it does not need to. Instead, it solves a specific problem: creating a secure internal connection when contractors cannot easily reach the outside of the pipe.
For merchants and distributors, IN-X is also a useful product to keep in stock for contractors who regularly deal with awkward drainage repairs.
