In professional racing, heat is the enemy of every seal on the car. When your brakes are glowing and that heat transfers through the hub to the wheel, standard rubber grommets can become brittle, crack, or even melt, leading to catastrophic pressure loss. The Longacre 52-50301 High-Temp Silicone Grommets are the premium upgrade for teams utilizing the TIRELIEF™ Quick Check valve stem system.
Manufactured from advanced High-Temperature Silicone, these grommets are designed to maintain their elasticity and sealing integrity even under the extreme thermal loads found in heavy-braking asphalt or high-intensity dirt racing.
Key Features
-
High-Temp Silicone Formula: Engineered to survive temperatures that would cause standard black rubber to fail, ensuring a leak-free seal during long-distance events.
-
Quick Check System Optimized: Specifically designed to fit the internal sealing surface of Longacre TIRELIEF™ Quick Check (QC) valve stems.
-
Superior Chemical Resistance: Resists degradation from tire chemicals, moisture, and rim cleaners, maintaining a soft, pliable seal over multiple tire changes.
-
Bright Red Identification: The high-visibility silicone material makes it easy for tire technicians to verify that the high-temp upgrade is installed at a glance.
-
Essential Maintenance Item: Grommets are wear items; replacing them regularly with high-temp silicone versions prevents "mystery leaks" that can ruin a car's handling.
