Factory coolant hose T fittings are molded hose or made out of plastic and are prone to cracking at junctions, causing coolant loss. Replace your worn or leaky factory coolant hose system with >PPEs Performance Silicone Coolant Hose Kit.

Perfect for your stock or highly modified Duramax 6.6L diesel truck. Engineered for performance and durability, featuring 4-ply heat-resistant internal fibers that provide strength against high-pressures and temperatures. >PPEs Silicone Coolant Hose Kits incorporate TIG welded, polished 304 stainless steel T fittings that eliminate any chance of failures at the T junctions.

Durable 5mm thick silicone is twice as thick as the factory hose to ensure long-lasting performance. The quick-connect/disconnect (LBZ, LMM, LML) end is made from billet aluminum and 304 stainless steel. T-Bolt clamps and worm-drive fasteners ensure a tight fit that performs better than factory.

The PPE Performance Silicone Coolant Hose Kit is a direct, bolt-on upgrade that requires no cutting or modifications. Perfect factory fit with better-than-factory performance.
