HPS High Temperature Reinforced Silicone Cap

DESCRIPTION

HPS high temperature 3-ply reinforced silicone cap. These are great for plugging unused inlets/outlet nipples that are left over from coolant bypasses, reroutes, etc. with a high quality cap that will last.

Cheap rubber or thin silicone vacuum caps can have all kinds of issues when used where they shouldn't be like leaking, ballooning/bursting under pressure, melting from heat, etc. Vacuum caps have no reinforcement and are intended for vacuum and very little pressure. These HPS Reinforced Silicone Caps are the right way to plug unused ports for the air or coolant systems!
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. Note: NOT designed for use with fuel or oil.
