The silicone material maintains flexibility over time, preventing cracking and hardening that can occur with standard rubber hoses.

Specialty worm drive clamps included in the kit feature W-style inner liners, which ensure even pressure distribution around the hose circumference. These clamps are crafted from stainless steel, offering excellent resistance to moisture, road salts, and engine chemicals, thereby extending the lifespan of the entire cooling hose assembly.
