3-1/2 in - 4 in ID x 6 in L, 4-Ply Silicone Charge Air Cooler CAC Hump Coupler Hose Cold Side

HPS Performance 3-1/2 in - 4 in high temperature 4-ply polyester reinforced silicone charge air cooler (CAC) cold side hump coupler hose with 6 in length, part number CAC-350-400-COLD, is engineered to meet and exceed SAEJ20 industry standards, providing a high-performance connection between engine-mounted charge air system components. This cold side CAC 3-convolute hump coupler bellow isolates heavy engine vibration and compensates for slight axial misalignments to protect turbocharger and intercooler piping from mechanical stress and fatigue. It is built for extreme-duty industrial, automotive, and marine environments with a temperature range of -65 deg. F to 350 deg. F (177 deg. C). The 4-ply polyester reinforcement offers superior burst pressure resistance and structural integrity compared to standard polyester-reinforced hoses, making it ideal for heavy-duty trucks, buses, and power generation systems. Hose inside diameter: 3.5 in - 4 in (89mm - 102mm). Hose length: 6in. Number of stainless steel rings: 3. Hose outside diameter: 3.9 in - 4.45 in (99mm - 113mm). Wall thickness: 5mm. Color: blue. The premium silicone construction is UV and ozone resistant, ensuring a long service life without hardening or cracking in harsh engine bays. This silicone hose is NOT compatible with fuel or oil.
