The high temperature reinforced Blue silicone cap from HPS Performance is designed specifically for installation on your cooling system.
Vacuum caps have no reinforcement and are intended for very little pressure and vacuum.
Manufactured just like our reinforced silicone radiator hoses, the HPS Reinforced Silicone Caps feature 3 layers of polyester webbing for reinforcement, ensuring they withstand the high temperatures and pressures of your cooling system for years.
Compatible with coolant, water, air, turbocharger bypass valve ports, vacuum ports, throttle body water ports, heater cores, and much more.
