Upon first glance, HPS Reinforced Silicone Caps for air and coolant may look like traditional vacuum caps, but unlike vacuum caps, HPS Reinforced Silicone Caps are designed specifically to be installed on your cooling system, making them a permanent solution to leaky coolant bypass and vacuum ports, an issue which vacuum caps only mend temporarily. Manufactured with 3 layers of polyester webbing for reinforcement, HPS Reinforced Silicone Caps contain the durability and efficiency to last years. This sturdy construction makes HPS Reinforced Silicone Caps capable of withstanding the high temperatures and pressures of your cooling system. HPS Reinforced Silicone Caps are compatible for use with coolant, water, air, turbocharger bypass valve ports, vacuum ports, throttle body water ports, heater cores, and much more. HPS reinforced silicone caps are not compatible with fuel, oil, or any petroleum-based products.
