S Seals is made from elastomer and two metal garter spring. The metal garter spring is incorporated into the elastomeric seal element. The one-piece S seal eliminates the installation issues that may occur when using multi-component seals. It can be stretched into place without splitting or damaging the non-extrusion components. S seal can be manufactured to accommodate almost any gland size, incl...

The convertible rotary seal has a housing for receiving the polishing rod. A mandrel is rotatably mounted in the seal housing and surrounds the polish rod. A wear sleeve surrounding the mandrel engages a primary seal. A secondary seal engages the mandrel and polish rod and rotates therewith but may be converted for use as a static seal if necessary. A locking mechanism selectively secures the mand...

When designing a cryogenic seal, the first step is to determine the operating temperature range of the seal. Typically, cryogenic seals operate below -65 degrees Fahrenheit. When designing seals of this level (high temperatures are around 300 degrees Fahrenheit), it is necessary to understand what degree of leakage control is required on the low temp end. However, there may be an allowable leakage...
