PTFE is the abbreviation of Polytetrafluoroethylene, also name is Teflon. PTFE is used in a variety of industrial products including gaskets, bearings and parts for valves, pumps and hydraulic cylinders. PTFE offers the following characteristics: • Low Friction, good self-lubricating function. • Good Electrical Insulation. • Wide Temperature Range (from 250℃+ to -195℃) • Excellent Acid & Chemi...

Backup Ring (anti-extrusion rings) fit in the gland between the seal and the clearance gaps to provide zero clearance. Back-up rings provides additional resistance support to the seal and minimizes the risk of the seal being squeezed out of its housing under pressure. Although they do not be designed with sealing function in themselves. They used with o ring play an important role in whole sealing...

Spring Energized Seal consists of two components, a polymer-based seal jacket and the spring. Jackets are typically made from different PTFE material blends, which have low friction, high and low-temperature range, and broad chemical and media compatibility. The seal jacket is typically machined in the shape of a “U”. Installed with the open side of the “U” facing the system pressure.This is for t...
