Product Features
  • 70 Shore A Red Silicone Elastomer & High-Heat Anti-Hardening: Engineered with signature red high-purity silicone (VMQ) compounding rated at 70 Shore A hardness, distinct from rigid 90-durometer hydraulic seals. It retains exceptional flexibility and elasticity under continuous elevated thermal exposure (150°C–200°C), eliminating heat-induced embrittlement, hardening, and cracking. 
  • Low Thermal Compression Set & Coolant Chemistry Resistance: Specifically formulated to resist chemical degradation from CAT Extended Life Coolant (ELC) and water-glycol mixtures. It features a low thermal compression set, maintaining a continuous resilient sealing force against mating joint surfaces during severe thermal cycling and engine cool-downs. 
  • Low Closure Force Conformability & Surface Anti-Adhesion: Demonstrates high surface conformability under low clamp loads, effectively bridging micro-imperfections on rough cast-iron or aluminum fluid flanges. Designed with anti-adhesive surface properties, it minimizes distortion during assembly and prevents joint sticking during overhaul teardowns.
