Viking Johnson MaxiFit - Universal Pipe Couplings
MaxiFit universal pipe couplings are designed to accommodate plain ended pipes with different outside diameters. One fitting is able to connect a wide variety of pipe materials including steel, ductile iron, PVC, cast iron, GRP and asbestos cement pipes amongst others. The range is designed and manufactured under quality management systems to BS EN ISO 9001 and meets the requirements of the UK Water Regulations & EN 14525.
Wide Tolerance.
With up to 34mm tolerance on the pipe OD it not only eases installation but can reduce the need for expensive and time consuming trial holes, reduce stock holding and increase stock turn over. MaxiFit is an adaptable and economic solution to most pipe connections. All products in the range have a test pressure of 24bar on water (9bar on gas) and are suitable for 16bar working pressure for water (6bar on gas)..
Quick & Efficient Installation.
The versatile range is pre-assembled with an innovative gasket which has ‘slide easy’ ribs that reduce friction on pipes at the upper tolerance range of the fitting, providing maximum sealing pressure, even on scored, pitted and corroded pipe surfaces. The captive non-rotating bolt heads require just a single spanner to install with just one standard bolt torque across the range. These features allow for a quick and efficient installation even in the most difficult of conditions..
Extensive Range
The expansive range is available in sizes DN40 up to DN600and includes MaxiFit couplings & MaxiFit Xtra long sleevedcouplings, MaxiStep reducing couplings, MaxiDaptor flangeadaptors, MaxiCap, MaxiThread End Cap, & MaxiFit Large Diameter couplings & flange adaptors.
- Design life expectancy of 50 years, established by rigorous `Accelerated Age Testing` which subjects product to working pressure at 80°C for 1000 hours
- Wide tolerances permit lower stock holding
- Extensive range is available in sizes DN40 - DN300
- All models accommodate angularity between pipes which allows for normal pipeline movement caused by ground settlement. Couplings and reducing couplings allowing for 6° total angular deflection (3° total on the flange adaptors)
- A rigorous bolt torque test is completed to confirm that the bolt, end ring and adaptor bosy are capable of withstanding bolt over-tightening to 1.5 times maximum recommended torque
A unique gasket with distinctive circumferential ribs provides a `slide easy` fit for maximum sealing on scored, corroded or pitted pipe.
Excellent Corrosion & Damage ProtectionCoated 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 InstallationCaptive, non-rotating bolt heads require just a torque wrench to install.
Flexible FitFlared end to the sleeve forms a deep gasket chamber to give maximum possible pipe adjustment.
