Meets Original Equipment specifications
Special design for easy remove and install. Made from premium materials
The SWIV-EL design allows the cap to be installed and removed much easier than conventional radiator caps because the shell of the cap rotates independently of the upper sealing gasket, stem, and the bottom plate. This design allows you to more easily grasp and remove the cap for testing or replacement. The best materials are used for long life.Threaded to match any SIGG water bottle, the SIGG Screw Top Cap provides leak-proof closure and
enables you to easily carry your bottle or clip it conveniently to your backpack with the use of a carabiner or similar attachment.
