High temperature seals
Y16, Y19, Y66, Y99
Features
- Rotating bellows seal
- Balanced
- No dynamic O-Ring, no hang-up, no shaft sleeve damage
- Uniform seal face loading
- Independent of direction of rotation
- Ideally suited for highly corrosive and abrasive media
- Compact design
Advantages
- Over 35 years of running reference in the field
- Resistant to abrasive particles
- Self cleaning, non-clogging design
- Long seal life due to vibration dampeners at bellows
- Ideal seal for very low as well high temperatures
