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.
MaxiDaptor provides wide-tolerance flange adaptation across multiple pipe materials, featuring multi-drilled flanges, 3° angularity, and simple installation using a single spanner for fast, versatile pipeline connection.
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 MaxiDaptor on gas, please verify that the network owner sanctions the use of the fitting for your intended application.

Plain Ended Pipe Connections to Flanged Fittings
Cast Flange Design
All cast flanges feature multi-drilling capability, allowing universal compatibility with a wide range of pipeline standards. Each flange incorporates an extended sealing face engineered to maintain high sealing integrity under varied operating conditions, ensuring dependable performance in demanding environments.
Angular Deflection Capability
The flange geometry is designed to accommodate natural angularity between connected pipes, supporting movement caused by ground settlement or thermal expansion. This flexibility reduces stress on the pipeline and helps preserve joint integrity. Flange adaptors provide a total angular deflection of 3°, enabling reliable operation where minor misalignment or movement may occur during installation or service.
Universal Pipe Connections
MaxiDaptor connects plain-ended pipes across a broad 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 simplifies installation and reduces the need for trial holes. The wide tolerance range lowers stock requirements and increases turnover by covering more pipe scenarios with fewer sizes.
Pressure Performance
All MaxiDaptors 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
MaxiDaptor has a material flexibility and wide tolerance making it ideal for replacing damaged pipe sections. Fewer sizes are required for emergency repairs, and MaxiDaptor enhances accessibility in confined spaces.
Quick & Efficient Installation
Pre-assembled gaskets with ‘slide easy’ ribs reduce friction and maintain sealing pressure even on corroded pipes. Captive, non-rotating bolt heads allow installation with a single spanner and 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 MaxiDaptor Flange Adaptors
Time saving – The MaxiDaptor proven design delivers fast installation.
Built in angular flexibility – Handles natural pipeline movement from ground settlement. 3° deflection on flange adaptors for reliable alignment.
Wide tolerance – Reduces the need for large stock holdings.
50 year design life – Extreme testing through accelerated ageing at 80°C under pressure for 1000 hours.
Over torque tested – Can withstand 1.5 × maximum recommended torque without failure.
Rilsan coating – Provides exceptional protection against corrosion, impact, abrasion, and chemicals.
Design Benefits
Ultimate Flange Drilling Versatility
All cast flanges have multi drilling including; BS EN 1092-2, ISO 7005 1:1992, (PN10/16), BS10: 1962 (Table ADE), ANSI/AWWA.
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 products have captive, non-rotating bolt heads require just a torque wrench to install.
Long Sleeved Large Diameter MaxiFit
All Large Diameter MaxiDaptor products (DN350 – DN700) have a long sleeve length as standard; this is a major benefit to the installer, allowing for greater cutting tolerances and a greater pipe insertion depth sealing beyond corrosion damaged pipe ends to create a safe and permanent repair.
