High Quality PTFE Back-up Ring

PTFE back-up ring seal with low pressure, such as the use of O-ring, star-shaped ring and U-ring. Can significantly enhance and improve such ring sealed pressure capabilities and service life, has been widely used in hydraulic sealing system.

1, the wide temperature range;

2, the friction is small;

3, non-absorbent;

4, does not occur in the 177 °C temperature aging.

5, high precision;

6, excellent chemical resistance, can be used for almost all of the media;

7, no hardening of breakage;

PTFE back-up ring is made of pure PTFE and its composite block O-back-up ring for dynamic sealing p ≥ 10mpa located Circlip bearing surfaces of the O-ring, a single compression set up a retaining ring, the double-sided compression, set the two back-up ring. PTFE back-up ring for hydraulic O-ring seal, working pressure 0-70mpa temperature: -40 ° C - +200 ° C Suitable medium: hydraulic oil, water, steam.
