FIGHTING CORROSION! Tramec Sloan's Air Tanks have you covered, inside and out! Our American-Made Air Tanks employ a 3-Step exterior finishing process with an industry leading interior finish to help you fight corrosion. SAE J10 requires just 48 hours of exterior salt spray resistance. However, Tramec Sloan air tanks go above and beyond with 500 HOURS of salt spray resistance! Internally, our air tanks pass the same 500 hours, but also meet the stringent military spec MIL-PRF-16173 Grade 2. When paired with a Tramec Sloan drain valve, our Air Tanks ensure years of trouble-free operation! From under the hood, to the back of the trailer...We've got you covered!
