Unique Stant Safety Features

Stant Fuel Cap
Functional and Safety Features

Pressure Relief Prevents fuel vapors from exiting the fuel system under normal operating conditions Allows an escape path for pressure in an impact situation where the fuel tank has collapsed Permits pressure to escape in the event of a Vapor Management System malfunction such as a plugged vent line
Vacuum Relief Prevents fuel vapors from exiting the fuel system via the fill tube under normal operating conditions Allows an alternative path for air to flow into the fuel tank in the event that there is an obstruction in the Vapor Recovery and/or Vapor Management Systems Permits fuel system to normalize during natural vacuum situations For example, a hot fuel tank being cooled down by a drive through car wash
Lost Motion During a crash the cap handle is allowed some freedom to rotate (from 60° to 180°) while maintaining proper O-ring compression Aids in the prevention of potential fuel leakage in a crash or impact
Torque Override Aids in proper installation of fuel cap Provides audible “click” for customer Allows for proper O-ring compression
Break Away Groove Allows for O-ring to maintain proper compression during a crash or impact even is some of the cap is broken away Prevents potential fuel leakage during a crash or impact
