Keep your fleet moving with precision-engineered rubber components designed specifically for Isuzu’s heavy-duty performance.
For heavy-duty cooling, our Isuzu Radiator Hoses are the industry standard. Utilizing Boss Rubber Supreme Quality canvas-reinforced materials, these hoses are specifically engineered for the Isuzu NPR 4.3 and NKR 3.3 (AF & Pak Models). We also stock specialized radiator hoses for larger industrial models like the Isuzu FTR, FVR, and the heavy-duty TXD 55. These hoses are designed to resist oil, ozone, and extreme heat, preventing the common “cracking” seen in standard aftermarket rubber.
Protecting your engine starts with a clean air supply. Our Isuzu Air Cleaner Pipes and intake hoses (including the MM-1 NPR 4.3 and JCR models) are made from high-grade Supreme Rubber to ensure a vacuum-sealed connection. Unlike cheap plastic alternatives, our rubber pipes won’t warp or crack under high engine temperatures, preventing harmful dust from entering your turbocharger or cylinders.
Reliable coolant circulation is critical for Isuzu diesel engines. Our catalog features Water Body Bends (Small & Big) for the Isuzu NKR Pak Model and MT-112. These specialized bends are molded with industrial-strength rubber to maintain shape under high suction. For older industrial models, we offer the Isuzu TXD 55 Big Lower Hose and water pipes, ensuring even legacy fleets stay operational.
