High Performance Seals

Categories: ,


ValveTech high performance static seals provide exceptional leakage at low cost. A metal spring element, machined from solid bar stock, loads a soft, replaceable sealing element. All parts are reusable but the inexpensive sealing element can easily be replaced when worn or damaged.

Competing seal designs express leakage as low or tight. ValveTech seals specify explicit external leakage rates that can exceed 5 x 10-5 sccs helium as measured on a helium mass spectrometer.

The ValveTech seal is especially suited and was originally designed for cryogenic applications. Most cryogenic seals are single use only and must be discarded after each use. The ValveTech seal is designed for multiple uses. Only the inexpensive sealing element may need replacement

The seals can be designed to be compatible with any flow media. The spring element can be manufactured from a variety of metals, including stainless steels and Inconel. The sealing element can be manufactured from any thermoplastic, Teflon or other soft material. Gold and silver plated elements can be provided for high temperature service.
