16mm (5/8") Blue Silicone Heater Hose

16mm (5/8") blue silicone heater hose (part SILHH16) is a mid bore coolant hose for larger heater circuits and intercooler plumbing, where the extra flow is needed and the run passes close to hot exhaust components. Silicone holds its properties through heat cycling where rubber hardens and splits, which is why it is specified on vehicles and plant that cannot afford a coolant failure.

Key features

• Nominal inside diameter 16mm (5/8")
• Meets or exceeds SAE J20R1, Class A
• Temperature range -55°C to +180°C
• High performance silicone with one ply polyester fabric reinforcement
• Ozone resistant and oil splash resistant
• Corrosion resistant and stable through repeated heat cycles
• Sold by the metre or in coils (7.5 m and 91.4 m)
• Not suitable for fuel or oil transfer

Applications

• Larger heater circuits
• Intercooler and charge air connections
• Truck and bus coolant lines
• Marine and industrial engines
• Performance and race builds

Compatibility and fitting

• Sized on inside diameter: 16mm hose fits a 16mm spigot or outlet
• Use a smooth band or T-bolt clamp from the clamp range; silicone is softer than rubber and a perforated band can bite the wall
• For fuel lines use SAE 30R7 fuel hose, not silicone
• Matching silicone clamp kits are in the silicone hose range

Does silicone need a different clamp?

It works best with a smooth band or T-bolt clamp. A perforated band can bite into the softer wall over time, especially on a line that heat cycles every day.

Sizes from 6 mm to 25 mm are in the blue silicone heater hose range.
