• 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
  • 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

Pipe Materials

HEP30 Ductile Iron Steel PVC Cast Iron Asbestos Cement Stainless Steel PE GRP ABS Concrete Copper

Applications

Water Gas

1 Simple Installation

Available as standard and long sleeve versions, the MaxiFit Xtra simplifies the installation further, allowing for greater cutting tolerances and a greater pipe insertion depth - sealing beyond corrosion damaged pipe ends to create a safe and permanent repair.

2 Excellent Repair Product

MaxiStep reducing couplings are designed to provide transitions between pipes of different nominal bores simplifying installations when repairing old pipe with new.

3 Accommodates Pipe Movement

All models accommodate angularity between pipes which allows for normal pipeline movement due to ground settlement. Couplings and reducing couplings allow for 6° total angular deflection
