DogBone High Temperature Reinforced Silicone Cap - 7/8" ID (22mm) w/ Hose Clamp

DogBone Reinforced Silicone Caps

Unlike traditional vacuum caps that can’t handle pressure, DogBone Reinforced Silicone Caps are built for durability under heat and load.

Manufactured using the same process as high-quality silicone radiator hoses, these caps feature three layers of polyester webbing for reinforcement, ensuring long-term performance in high-pressure, high-temperature environments.

Perfect for use with coolant, water, air, turbocharger bypass valve ports, vacuum ports, throttle body water ports, heater cores, and more.
(Not compatible with fuel, oil, or petroleum-based products.)
