Pipe Repair products offer a fast, safe way to seal splits, holes, and corroded sections instantly – often under full system pressure – avoiding the need for expensive and time-consuming network shutdowns.
Ideal for repair and maintenance applications, this coupling delivers fast, reliable installation. Featuring up to 6° angular deflection, a longer sleeve for an increased setting gap, and a single spanner helps simplify site repairs while reducing installation time.
There are restrictions on the minimum thickness of the stainless steel, PVC-U and GRP pipes for them to work with Viking Johnson flexible couplings. Consult Viking Johnson for further guidance
Caveat 3
While Viking Johnson has tested and approved the use of MaxiFit on gas, please verify that the network owner sanctions the use of the fitting for your intended application

A Versatile Solution for Pipe Jointing.
Greater Cutting Tolerance
The MaxiFit Xtra long-sleeved coupling provides increased cutting tolerances and a greater pipe insertion depth, enabling installers to seal well beyond corrosion-damaged pipe ends. This design simplifies installation and delivers a safe, permanent repair.
Universal Pipe Connections
MaxiFit Xtra long-sleeved couplings connects plain-ended pipes across a wide range of outside diameters and materials, including steel, ductile iron, PVC, cast iron, GRP and asbestos cement. This versatility allows one fitting to replace multiple material-specific options, improving efficiency and reducing inventory complexity.
Wide Tolerance Design
With up to 34 mm OD tolerance, MaxiFit Xtra long-sleeved coupling simplifies installation and reduces the need for trial holes. The broad tolerance range also lowers stock requirements and increases turnover by covering more pipe scenarios with fewer sizes.
Pressure Performance
All MaxiFit Xtra long-sleeved couplings are tested to 29 bar (water), validating the working pressure of 16 bar (water) and 6 bar (gas), to ensure consistent sealing performance.
Versatile Repair
Material flexibility and wide tolerance make MaxiFit Xtra long-sleeved couplings ideal for cutting out and replacing damaged pipe sections. Fewer sizes are needed for emergency repairs.
Quick & Efficient Installation
Pre-assembled gaskets with ‘slide-easy’ ribs reduce friction and maintain sealing pressure even on corroded or scored pipes. Captive non-rotating bolt heads allow installation with a single spanner and one standard torque.
Quality & Compliance
Manufactured under BS EN ISO 9001, the range meets BS EN 14525 performance requirements, with DN40–DN300 independently tested by BSI.
Why Choose MaxiFit-Xtra Long Sleeved Couplings
Time saving – MaxiFit Xtra long sleeved deliver fast installation.
Built in angular flexibility – Handles natural pipeline movement from ground settlement. 6° deflection on couplings for reliable alignment.
End caps – All sizes available with MaxiCap end caps.
Over torque tested – Can withstand 1.5 × maximum recommended torque without failure.
Wide tolerance – Reduces the need for large stock holdings.
50 year design life – Proven through accelerated ageing at 80°C under pressure for 1000 hours.
Rilsan coating – Provides exceptional protection against corrosion, impact, abrasion, and chemicals.
Design Benefits
Optimised Gasket Design
A unique gasket with distinctive circumferential ribs provides a ‘slide easy’ fit for maximum sealing on scored, corroded, or pitted pipe.
Flexible Fit
Flared end to the sleeve forms a deep gasket chamber to give maximum possible pipe adjustment.
Excellent Corrosion & Damage Resistance
Coated in black Rilsan Nylon 11 which is WRAS listed and has excellent resistance to impact, abrasion, weathering and chemicals. It also has good thermal stability and flexibility to accommodate for rough site handling.
Simple Installation
All the MaxiFit Xtra Long Sleeved Couplings have captive, non-rotating bolt heads require just a torque wrench to install.
