Description
This premium repair double lock coupling is engineered for rapid, reliable repairs to pressurised pipelines, minimising downtime and disruption. Designed to clamp securely around damaged sections of pipe, it restores service quickly without the need for extensive cutting or system replacement.
Suitable for use on a wide range of pipe materials, this robust coupling is ideal for industrial, commercial and utility networks handling water and many other compatible fluids. With multiple outside diameter and width options available, it offers a versatile, high-integrity solution for both planned maintenance and emergency pipeline repairs.
Product Features
- Double lock design ensures a secure, leak-resistant seal on pressurised pipelines during and after repair.
- Compatible with multiple pipe materials, allowing flexible use across existing mixed-material networks.
- Available to suit outside diameters of 44–54 mm, 55–65 mm, 70–80 mm, 85–95 mm, 105–115 mm and 131–141 mm.
- Choice of 85 mm or 140 mm width to suit both compact access areas and applications needing extended sealing length.
- Manufactured from corrosion-resistant metal components with durable sealing elements for long service life.
- Clamps around the existing pipe, reducing the need for cutting out long sections of damaged line.
- Designed for rapid installation using standard hand tools, helping to restore flow quickly.
Key Features and Benefits
- Enables fast, on-site repair of leaks and cracks under pressure, significantly reducing system downtime.
- Multi-diameter options allow one coupling type to cover a wide range of pipeline sizes across your site.
- Broad material compatibility means a single solution can be used across different pipeline sections and upgrades.
- Double locking mechanism enhances joint security, helping to maintain integrity under fluctuating operating pressures.
- Compact design and shorter width option make it ideal where access is restricted or excavation is limited.
- Robust construction lowers maintenance needs and replacement frequency, supporting long-term operational reliability.

Frequently Asked Questions
Can this repair coupling be fitted while the pipeline is still under pressure?
The coupling is designed for fast repairs on pressurised lines, but whether it can be installed live depends on your specific system pressure, medium and safety procedures. Always follow site risk assessments and relevant guidance, and where in doubt, isolate and depressurise the line before installation.
How do I choose the correct size of coupling for my pipe?
Measure the actual outside diameter of the pipe at the repair location using a suitable measuring tool, then select the coupling variant whose stated outside diameter range fully covers that measurement. Also choose the width (85 mm or 140 mm) based on available access and the length of pipe you need to cover.
Is this coupling suitable for any pipe material and fluid?
The coupling is suitable for use on a range of common pipe materials and many water and compatible fluid systems. However, you must check compatibility with the pipe material, operating pressure, temperature and the medium being conveyed. Consult your system designer or engineer if you are unsure about suitability for a specific application.
