SPRING ENERGIZED PTFE SEAL
Ultra Seal Series 700 : U-Spring
Click to view UltraSeal 800 Helicoil Springs
The Ultra Seal Series 700 line of radial and axial seals are energized by a unique cantilever spring energized seal design. This combination of seal profiles and spring design was developed for use in a wide range of applications requiring a balance between maximum sealing ability and low friction operation.
Radial Seals
Descriptions:
Series 700 – Standard profile for general applications. Rounded sealing lips for optimum performance in low to medium pressure and/or speeds.
Series 700E – With extended heel for use in higher pressures and temperatures.
Series 701 – Standard profile for use in wiping/scraping applications. Scraper ID is ideal for service involving viscous media and abrasive particles.
Series 701E – Wiper seal with extended heel for higher pressures and temperatures.
Series 702 – Standard wiper seal profile for piston sealing applications. Wiper on the seal OD.
Series 702E – Wiper piston seal with extended heel for higher pressures and temperatures.
Series 703 – Standard profile rotary seal (similar to 700) but with a flange to permit clamping against the housing to prevent seal rotation with the shaft.
Series 704 – Scraper profile rotary seal (similar to 701) but with a flange to permit clamping against the housing to prevent seal rotation. For slow rotary service only.
Axial Seals
Series 705 – Inside pressure face seal for axial sealing applications. For static and very slow dynamic service.
Series 706 – Outside pressure face seal for axial sealing applications. For static and very slow dynamic service.
