Pure PTFE Flat Washer Backup Ring / Mechanical White Seal Ring Pump Parts

PTFE (Polytetrafluoroethylene)

Known as the gold standard, PTFE material is often the first choice for many advanced applications such as aerospace, electronic, medical, chemical industry due to its superior lubricity, temperature and chemical resistance, biocompatibility and lowest coefficient of friction.

Properties

1, Low coefficient of friction;
2, Flexibility at low temperatures and thermal stability at high temperatures,Broad working temperature range (500°F/260°C – -292°F/-180°C);
3, Chemically resistant – all normal solvents, acids, and bases;
4, Low dielectric constant and low dissipation factor;
5, Non-flammability;
6, Non-stick, Easy to clean;
7, Long-term weathering;
8, High arc resistance, surface and volume resistivities

Product description

Back-up Rings have no intended sealing function.
They are protective and supporting elements made from extrusion-resistant materials which generally have a rectangular cross section. They are installed in a groove together with an elastomeric sealing element preferably with a corresponding O-Ring in static applications.Due to the tight fit of the Back-up Ring in the housing, they prevent extrusion of the pressurised elastomeric sealing element into the sealing gap.
