Description & Feature
The HPS high-performance silicone air intake hump hose is engineered as a superior direct replacement for Caterpillar part numbers 268-4743 and 217-7088. Designed to overcome the common failure points of OEM silicone and rubber hoses, this air intake hose features 5-ply aramid reinforcement, providing exceptional burst strength and thermal stability even under extreme boost pressures and high-temperature operating conditions of up to 500F. The interior is equipped with a specialized fluoro-lining, creating a barrier against oil mist and fuel vapors that typically degrade standard silicone and rubber hoses over time. The construction is further fortified with thicker, more robust stainless steel rings, which maintain the hose's structural integrity and prevent ballooning during intense vibration and load changes. By combining advanced materials with heavy-duty hardware, this HPS replacement delivers significantly longer service life and reduced maintenance downtime for your machinery. Wall thickness: 6mm, inside diameter: 4" (102mm), outside diameter: 4.48" (114mm), length: 7.5" (191mm), number of rings: 2.
