Description
This premium repair double lock coupling Type II is designed for permanent, reliable repair of pipelines operating under pressure. Engineered to provide a secure, leak-tight seal around damaged or corroded pipe sections, it allows you to restore system integrity quickly and with minimal disruption.
Suitable for a wide range of pipe diameters and available in multiple widths, this coupling is ideal for water, process, and industrial pipelines in utilities, manufacturing, construction and maintenance environments. Its robust construction and double locking design ensure long-term performance in demanding applications.
Product Features
- Available for outside pipe diameters from 44–54 mm up to 215–225 mm, covering a broad range of pipeline sizes.
- Three coupling widths available: 85 mm, 140 mm and 210 mm, to suit localised or extended repair areas.
- Double lock mechanism provides enhanced grip and sealing performance on pressurised pipelines.
- Designed for permanent repair of in-service pipelines without the need for full line replacement.
- Suitable for use on a variety of common pipeline materials, depending on system design and compatibility.
- Robust construction for use in industrial, utility and commercial service conditions.
- Externally mounted clamp-style design for rapid installation over damaged pipe sections.
Key Features and Benefits
- Enables permanent repairs under pressure, reducing downtime and avoiding costly system shutdowns.
- Wide diameter range allows one product family to cover multiple pipeline sizes, simplifying specification and stocking.
- Choice of widths means the repair can be tailored to the length and severity of pipe damage.
- Double locking arrangement provides a secure mechanical hold, minimising the risk of slippage or leakage over time.
- External fitting avoids the need for intrusive work on the pipe interior, helping maintain flow conditions.
- Durable design supports long service life, reducing the need for repeat maintenance at the repair location.

Applications and Ideal Uses
This repair coupling is intended for maintenance teams, contractors and engineers needing a reliable, long-term solution for damaged pressurised pipelines across a range of sectors.
- Emergency and planned repairs on water distribution and service lines.
- Industrial process and cooling water pipeline maintenance.
- Commercial building services pipe repairs (plant rooms, service ducts).
- Utility infrastructure maintenance for above-ground and accessible buried pipelines.
- Temporary containment that can remain in place as a permanent solution once installed and tested.
Frequently Asked Questions
Can this repair coupling be installed while the pipeline is still under pressure?
The coupling is designed for permanent repairs on pipelines operating under pressure, but the precise installation procedure and allowable pressure will depend on the system conditions and site method statements. Always follow local safety guidelines and consult a qualified engineer before working on live pipework.
Which pipe sizes does this double lock coupling Type II cover?
The product range covers outside diameters from 44–54 mm up to 215–225 mm, with specific variants for 44–54, 55–65, 70–80, 85–95, 105–115, 131–141, 159–169 and 215–225 mm. This allows appropriate selection for most small to medium pipeline sizes within that range.
How do I choose the correct width of coupling for my repair?
Select the width based on the length and location of the damage, as well as any surrounding corrosion or weakness in the pipe wall. The 85 mm width is suited to compact, localised damage, the 140 mm option provides additional coverage, and the 210 mm width is ideal where a longer section of pipe requires reinforcement.
