High Tolerance Pipe Couplings (Viking Johnson)

Features and Benefits:

Universal MaxiFit 1.5”-12”

The concept of MaxiFit is to optimize stockholding and simplify installation.  To achieve this, MaxiFit offers a tolerance range of up to 0.88”, having the effect of reduction of inventory to one size per nominal bore.  This is a benefit also appreciated by the installer, as only one product per size needs to be selected to effect a repair.

Full Range

The MaxiFit product range includes Couplings, Stepped Couplings, Flange Adapters and other specialized fittings such as MaxiStop, a Universal end cap.  The Couplings, Stepped Couplings and Flange Adapters are available from 1.5” to 12” in an unmatched range of nominal sizes, making MaxiFit the most complete coupling range available anywhere in the World. Joining the MaxiFit range are the New Large Diameter MaxiFit, MaxiStep, and MaxiDaptor.  These are available in nominal sizes 14” to 24” in a wide variety of straight couplings, stepped couplings and flange adapters.

Speed of Installation

MaxiFit products are stab-fit allowing quick and efficient installation, even in the most difficult of conditions without the need for dismantling.  All products have a standard bolt torque of 40-50 ft.lbs.

Ease of Installation

The gaskets feature a series of “Slide Easy” ribs, designed to reduce installation friction on pipes at the upper tolerance range of the MaxiFit, while a unique double angle sealing profile on larger sizes aids centralization of the coupling on pipes towards the lower end of the tolerance range.

Guaranteed Sealing

The unique “Slide Easy” gasket provides maximum sealing pressure, even on scored, pitted and corroded pipe surfaces, through its distinctive circumferential ribs.

Corrosion and Site Protection

All MaxiFit components, including nuts and bolts, are coated with the thermoplastic polymer, Rilsan Nylon 11.  Rilsan Nylon 11 meets the highest performance standards of adhesion, flexibility, penetration and impact resistance. MaxiFit products are equipped to withstand transport, storage, site and corrosion damage, eliminating the need for further protection such as on-site wrapping.

Product Quality

MaxiFit range products are designed and manufactured under quality management systems to BS EN ISO 9001:1994 and have been tested to the most exacting performance requirements. MaxiFit products also conform to the American Water Works Association standard AWWA/ANSI C.219 for bolted couplings. As with all Viking Johnson products, MaxiFit is designed to outlast the pipes on which it is fitted.
