Each valve is subjected to pressure testing. Individual valves are then taken at random from the production line for fatigue tests. These tests are carried out by continually repeating opening and closing throughout of 57 PSI at a temperature of 257°F (125°C).

-After many years of research, laboratory tests and field trials a labour saving tail piece is included as standard. This incorporates a special plastic thread coating that eliminates the need to use tape or thread sealant. A small drop of light oil on the tail piece before insertion into the radiator will help ease installation.
