BluTek™  is unique due to its Dual Core technology that blocks more moisture from entering the hose as opposed to other hoses on the market. The inner core is a tube made of a compound highly compatible with today’s SPF and coatings chemicals. The outer core is a tube made of a high-temperature, moisture-blocking compound that prevents moisture from reaching the inner tube.  This Dual Core hose is distinctive in nature because of its premier performance in moisture blocking, chemical compatibility, and temperature rating – all of which are included in the hose makeup, but also help reduce its overall weight. Competitor hoses simply do not have this level of performance in all three categories.
