[PN: RSCC-044-BLK] HPS 7/16" High Temperature Reinforced Black Silicone Coolant Cap Bypass Heater 11mm

We are proud to introduce the HPS Reinforced Silicone Caps for air and coolant. While they look a lot like traditional vacuum caps, the HPS Reinforced Silicone Caps are designed specifically to be installed on your cooling system. Vacuum caps have no reinforcement and are intended for vacuum and very little pressure.

The HPS Reinforced Silicone Caps are manufactured just like our reinforced silicone radiator hoses. With 3 layers of polyester webbing for reinforcement, you can be sure that HPS Reinforced Silicone Caps will withstand the high temperatures and pressures of your cooling system for years to come.

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.
