SPRING O RINGS

The Spring O Ring seals consist of a stainless steel strip formed into a precision spring then fully encapsulated in a jacket of FEP or PFA and is aimed for sealing at extremely low temperatures where traditional elastomers suffer from brittleness.

With low compression set capabilities, effective sealing can be down as low as -250 °C, in cryogenic situations as found in Pharmaceutical, food and chemical processing industries.

With inside diameters starting at 12.70 mm and 20 cross sections available, this high quality product can be produced on short lead times, to service a demanding market requirement.

Industries such as chemical, pharmaceutical and biotechnological all face low-temperature cryogenic environments. They operate in applications where it is extremely tough to accomplish an efficient gas or fluid sealing. Spring Energised O Rings are perfect for sealing in conditions, where standard rubber would be subject to brittleness due to exceptionally low temperatures. Low compression set permits efficient sealing in cryogenic installations in temperatures as low as -250°C. Spring O Rings contain accurately turned flat strip spring made out of stainless steel.
