Mount Engineering Plc has three subsidiaries:

Redapt and Raxton, established in the 1970s, specialize in the manufacture and supply of thread converting Adaptors and Reducers that are “Ex Certified”, which means that they have been certified for use in potentially explosive or hazardous areas. The products of both companies provide a method of insulating and protecting electrical wiring and installations in hazardous areas such as oil refineries where a stray spark from an electrical installation could have severe consequences. The requirement for thread converting components arises due to the diverse range of thread specifications incorporated into equipment used in hazardous areas. Hazardous area certification is intrinsic to the market that Redapt and Raxton sell to.

Hi-Flow was established in 1994 and is engaged in the stocking, distribution and merchanting of industrial valves and actuators to the oil, gas, petrochemical, process and related industries throughout the world.

The major end user markets for all three subsidiaries are the oil and gas and petrochemical industries; however, they also serve a range of other industrial markets including mining, waste water and pharmaceuticals.
