A spring energized seal is a type of dynamic seal that uses a spring to provide a constant force against the sealing surface. The spring is typically made of stainless steel, alloys sometimes even PTFE and PEEK, and it is compressed between two components, such as a gland and shaft. As the components move relative to each other, the spring compresses and deforms, creating a dynamic seal that preve...

The function of wear rings is to absorb forces in a piston and/or rod hydraulic cylinder, while eliminating metal to metal contact. Wear ring can extend the life of a hydraulic system: it’s faster and less expensive to replace a wear ring than an entire cylinder. The Guiding/Wear ring is a roll of tape that can be cut to a specific length according to the customer’s specifications. The wear ring o...

PEEK is one of the most radiation resistant plastics in common use. It can withstand exposure of 109 rad before any performance degradation occurs. PEEK can also operate successfully at temperatures up to 500 ° F. PEEK is usually used for back-up rings, bearings, and structural seal components such as seal carriers and valve blocks. It's a challenge to create a spring energized seal jacket out of ...

A wiper plug typically has an elastomeric body mounted on a mandrel and elastomeric external fins that bear against the inner wall of the casing. The fins wipe mud solids and other accumulated debris off the inner wall of the casing. The effectiveness of a wiper plug relies on at least one fin creating a seal against the surrounding casing or liner, and the body sealing against the mandrel. The el...
