Features and Benefits
Aluminum WeatherJacs are produced from 1100 series Aluminum, meeting ASTM B-209 standards. 1100 aluminum alloy is among the commercially pure wrought family (1000 or 1xxx series). With a minimum of 99.0% aluminum, it is the most heavily alloyed of the 1000 series. It is also the mechanically strongest alloy in the series. At the same time, it keeps the benefits of being relatively lightly alloyed (compared to other series), such as high electrical conductivity, thermal conductivity, corrosion resistance, and workability.
Numbered WeatherJacs are 2-piece pressed fittings which are pre-formed for 45 & 90 degree insulated bends for a variety of pipe size and insulation thickness combinations up to 14”³ x 1-1/2”³. All numbered WeatherJacs are produced in conformance to ASTM, C-585 & C-450 standards and come with the patented weather seal system.
