Replace the weak OEM plastic heater hose connector on your 2015-2016 GM 6.6L Duramax LML with the PPE Stainless Steel Heater Outlet Hose Connector for enhanced durability and reliability. The stock plastic connector is prone to cracking due to heat cycles and engine vibrations, leading to coolant leaks and potential engine damage.
PPE’s stainless steel connector is engineered for long-lasting performance, offering excellent corrosion resistance and the strength needed to withstand the harsh conditions of your engine bay. Designed to connect the 5/8" heater outlet hose to the 5/8" aluminum tubing on the engine side, this upgrade ensures a secure, leak-free connection that will last the life of your vehicle. Say goodbye to coolant leaks and enjoy peace of mind with PPE’s stainless steel replacement connector.
