James Walker Flemings
If there is an industrial application for specialised plastics then James Walker Flemings has probably made a product for it. The company produces hydraulic and pneumatic seals, diaphragms, hot cast polyurethane components and high volume injection mouldings. These products are used in a wide range of industries including food and drink, ceramics, and sewerage.
We market and service our products throughout the UK and export through other James Walker Group companies. We are equally at home with volume production or specialist products like our unique dual hardness seals that are used for pipe testing by the steel industry. In fact, pressures in excess of 50,000psi (3450bar)have been sealed.
