Usage:
Improved installers are available for Class D Duo-Cone seals [Class D Duo-Cone seals have a 12.7 mm (.50") diameter toric section]. The improvements to installers include:
1. The use of a more durable material.
2. A change in the profile of the lip which forces the toric into the housing.
3. An added lip to control the space between the seal ring and toric.
4. An added latching mechanism, on larger sizes, which holds the installer lips in alignment at the installer gap and keeps the gap from opening during seal installation. The latching mechanism also holds the installer open during its removal to prevent disturbing the installed seal assembly.
Improved Duo-Cone seal installer with latching mechanism.
The new installers can be used to service Duo-Cone seals that range from 171.7 to 394.5 mm (6.76 to 15.52") in diameter. Note from the chart that several of the new seal installers have the same seal ring diameter but different ramp angles. Because the new installers conform to both the seal ring and toric, it was necessary to replace the former seven different installers with fourteen improved installers. The chart that follows lists the new and former seal installers along with the seal ring diameter and ramp angle which dictate installer selection. A Special Instruction packaged with each new Duo-Cone seal assembly identifies the correct installer to be used with that seal assembly.
