TUSA RS-600 First Stage Cold Water Environmental Kit

You own a TUSA RS-680 Regulator and want to dive cold water or in heavily silt or contaminated water environments. To help protect your regulator from cold water or contaminated water environments you will need to install this kit. The Kit creates a barrier between the external cold/contaminates and the spring cavity of the first-stage regulator. In cold water the kit can help prevent icing of the first stage mechanism and in contaminated or heavily silted environments add an extra layer of protection. The end cap of the kit is made from marine grade chrome plated brass. Kit comes with installation instructions and is easy to install.
