Black High Temperature Silicone Coolant Cap Bypass Heater, 1-1/2 Length, 350F Max. Temp

The HPS Performance 3/8" high temperature reinforced black silicone cap is specifically designed to be installed on your cooling system. Unlike vacuum caps which have no reinforcement and are only intended for vacuum and minimal pressure, HPS Reinforced Silicone Caps are manufactured with three layers of polyester webbing for added strength. This ensures that they can withstand the high temperatures and pressures of your cooling system for years to come.

These reinforced silicone caps are compatible for use with coolant, water, air, turbocharger bypass valve ports, vacuum ports, throttle body water ports, heater cores, and more. They have a temperature range of -65 deg. F to +350 deg. F (177 deg. C) and a wall thickness of 4mm. The inside diameter is 3/8" (9.5mm), inside length is 1-3/16", and overall length is 1-1/2". Additionally, they are UV and ozone resistant.

It's important to note that HPS reinforced silicone caps should not be used with fuel, oil, or any petroleum-based products. They are made of High Temperature 3-ply Polyester Reinforced Silicone with a maximum temperature rating of 350 deg. F (177 deg. C). These caps are ideal for heavy duty pressure connections and provide excellent resistance for high temperature applications.

In conclusion, the HPS Performance 3/8" high temperature reinforced black silicone cap is a durable and reliable option for your cooling system needs.
