Silicon U Cup Seal

They feature inner and outer lips that seal against a rod or cylinder wall. Silicone offers excellent heat resistance and flexibility, making them suitable for high-temperature applications where polyurethane might fail.

Silicone U-cup seals are designed for high-temperature and chemical-resistant sealing, featuring a U-shaped profile with a typical hardness of 60-70 Shore A. 

• Material: Silicone Rubber (VMQ) or Fluorosilicone (FVMQ).
• Temperature Range: Typically handles extreme temperatures, commonly ranging from 
  

  ${-60}^{\circ }�$
   to 
  

  ${\mathrm{+230}}^{\circ }�$
   (
  

  ${-80}^{\circ }�$
   to 
  

  ${\mathrm{+450}}^{\circ }�$
  ).
• Applications: Ideal for high-temperature, food-grade (FDA-compliant types), and chemical-resistant environments.
