Pacific Performance Engineering 119025300 Silicone Upper & Lower Coolant Hose Kit Orange

The Pacific Performance Engineering (PPE) 119025300 is a performance silicone upper and lower coolant hose kit designed as a direct replacement for the factory cooling system hoses on the GM 6.6L Duramax diesel engine. Factory coolant hose "T" fittings are molded or made from plastic and are prone to cracking at junctions, creating a risk of coolant loss and potential engine overheating. PPE's kit addresses these factory weaknesses with premium materials and precision engineering.

Key Features:

• 4-Ply Heat-Resistant Construction: Internal fibers provide exceptional strength against high pressures and elevated temperatures found in diesel cooling systems
• 5mm Thick Silicone Walls: Twice as thick as the factory hose, ensuring long-lasting durability and resistance to deterioration
• TIG Welded 304 Stainless Steel "T" Fittings: Polished stainless steel couplings eliminate the risk of cracking or failure at "T" junctions — a known weak point on factory hoses
• Billet Aluminum & 304 Stainless Steel Quick-Connect End: The quick-connect/disconnect fitting (compatible with LBZ, LMM, and LML engines) is machined from premium materials for a secure, reliable connection
• Specialty Worm Drive Clamps with W-Style Inner Liners: Included two-piece clamps deliver 360 degrees of constant tension with interlocking surfaces that prevent leakage through thermal cycles and engine vibration
• Direct Bolt-On Upgrade: Requires no cutting or modifications — a perfect factory fit with better-than-factory performance
• Bold Orange Finish: Adds a performance look under the hood, available in orange

The PPE 119025300 silicone coolant hose kit is an ideal upgrade for both stock and highly modified Duramax 6.6L diesel trucks. The high-quality stainless steel clamps and fittings resist moisture and chemicals while providing superior clamping force throughout the engine's thermal cycle.
