A low cost, double-width arch, externally reinforced, moulded butyl expansion joint with twice the movement capability of standard expansion joints.

This expansion joint is commonly used in pulp and paper applications, as well as water and waste treatment. Special, hand-made versions of this joint are available in different elastomers and multiple arch types for other applications.

The MJ-70 double-arch expansion joint features a precision moulded elastomer compound reinforced with multiple plies of nylon. The shape of the arches provide a smooth, low turbulence flow which will handle process fluids with suspended solids.

Installation is easy due to the threaded Vanstone style rings, making them easy to align. Control units are also available.

The MJ-80 single-arch expansion joint features a precision molded elastomer compound reinforced with multiple plies of nylon. The spherical shape of the arch provides a smooth, low turbulence flow which will handle process fluids with suspended solids.

Installation is easy due to the threaded Vanstone-style rings, making them easy to align. Control units are also available.

Series MJ-90 – Molded Elastomer

MJ-90 molded elastomer expansion joints are designed to handle vibration, misalignment and movement in smaller diameter piping systems. The union ends provide a simple means of disconnecting the piping to service equipment such as pumps. The maximum angular movement of this joint is 45°.
