PTFE retaining ring, also known as Teflon retaining ring, is one of PTFE products. Polytetrafluoroethylene products include retaining rings, gaskets, gaskets, etc. Due to their excellent wear-resistant self-lubricating properties, Good elongation and compressive strength. Can be used under low oil and oil-free conditions and water lubrication. Widely used in a variety of gaskets, gaskets and other mechanical parts that require self-lubricating, abrasion, corrosion and oil resistance. It is mounted with an O-ring and a star-shaped ring to prevent the seal from being squeezed into the gap. In accordance with ISO3601, AS568A, BS4518, BS1806 standards, the material is tetrafluoroethylene or other polymers. The form of the retaining ring is: integral type, oblique cut type and spiral type, special shape can be sampled or drawing, Dongguan Teflon retaining ring manufacturers custom processing.

The retaining ring is used in dynamic and static sealing conditions, and the dynamic seal can be used in the outer seal (piston) and inner seal (piston rod). Dongguan Teflon retaining ring manufacturers should use the retaining ring if one of the following conditions occurs during the operation of the equipment. The pressure is above 8 MPa (in some cases the pressure is low); the tolerance between the sealed parts is large and the diameter is large and the radial clearance is large; the high reciprocating speed or the sharp speed change; the high frequency high temperature and temperature Great changes; intense pressure shocks and fluctuations; the system is not clean. Installation If pressure is applied to only one side of the O-ring and the star seal, place a retaining ring on the pressure side.

Polytetrafluoroethene is generally referred to as "non-stick coating" or "easy-cleaning material"; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids and bases and to various organic solvents and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its friction coefficient is extremely low, so it can be used as a lubricating agent, and it has become an ideal coating for the inner layer of water pipes.
