• Maintains performance under continuous high-temperature operation.
• Reinforced wall prevents collapse under vacuum.

Fits These Machines

• Marine racing engines
• High-performance boat cooling systems
• Custom marine exhaust and intercooler plumbing

On-The-Job Use

• Replacing worn coolant lines in high-output marine engines.
• Connecting heat exchangers or intercoolers in race boats.
• Rerouting coolant lines for optimal flow in a cramped engine room.

Specs At A Glance

Good To Know

Q: Is this hose suitable for use with marine coolants and additives? A: Yes, silicone hose is chemically resistant to ethylene glycol and propylene glycol based coolants. This makes it a reliable choice for the closed cooling systems common in marine racing.

Q: How does silicone hose handle the vibration found in marine engines? A: Silicone is naturally flexible and absorbs vibration better than rigid rubber or metal lines, which helps reduce stress on connections. This is a key benefit for high-vibration racing environments.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
