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

HPS Performance 3-1/2 in - 4-1/2 in ultra high temperature 4-ply aramid reinforced silicone charge air cooler (CAC) hot side hump coupler hose with 6 in length, part number CAC-350-450-HOT, is engineered to meet and exceed SAEJ20 industry standards, providing a high-performance connection between engine-mounted charge air system components. This hot 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 500 deg. F (260 deg. C). The 4-ply aramid 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 - 4.5 in (89mm - 114mm). Hose length: 6in. Number of stainless steel rings: 3. Hose outside diameter: 3.9 in - 4.88 in (99mm - 124mm). Wall thickness: 5mm. Color: orange. 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.
