TEFLON® SEALS

What are TEFLON® SEALS?

Seals are an integral component and design decision across a variety of engineered applications.

“Seals are everywhere. My career has provided an ever-expanding experience of new applications, seal designs and material developments which show no signs of diminishing. They are a key component of our houses, domestic appliances and vehicles while transport and virtually all industries are totally dependent on them for safe and reliable operation. They are often treated as a trivial commodity product, but the costs and consequences of a failure can be substantial.”

Robert Flitney

Teflon Seals are a family of sealing solutions, utilizing Teflon and Teflon Filled variant materials, to meet demanding application requirements. Teflon has almost universal chemical resistance, the lowest coefficient of friction of any known solid material, and wide working temperature range. Considering these properties, Teflon is an excellent choice in material for high-performance seals. Teflon Seals are at home in Cryogenic Space and Aerospace applications, chemical intense biomedical and pharmaceutical applications, and even in semiconductor manufacturing and processing.

        Spring Energized TEFLON® Seals

        Helical Spring

        helical spring for mechanical ptfe teflon seals

        The helical spring energizer design is intended for static applications due to the high unit load. It can be used in very slow or infrequent dynamic conditions when friction and wear are secondary concerns to positive sealing.

        This spring energizer design produces an evenly distributed load across each individual band. Our in-house manufacturing team maintains minimal gaps between coils. This tight spacing provides continuous load, reducing potential leak paths and failures.

        Cantilevered V-Spring

        Cantilever V Spring Seals utilize a V-Shaped spring pressed into a seal jacket. At installation the Cantilevered V-Spring is compressed, pushing against the legs of the seal providing positive sealing pressure. This type of spring energizer has a linear load curve and significant deflection range.

        Canted Coil Spring

        Advanced Slant Coil Springs are made from round wire which is coiled and formed into an elliptical shape on an inclined position. Unlike any other types of springs, Advanced Slant Coil Springs produce near constant spring force over a wide range of working deflection and provide outstanding stress properties and fatigue life.
