Important: do not use for fuel or lubricants.

A soft silicone line that holds its shape against engine-bay heat where standard rubber swells and perishes. Sold by the metre so you can replace exactly what you need — vacuum lines, coolant branches, washer feeds — in the correct ID.

Features:

• Silicone Build: Resists under-bonnet heat and pressure cycling far better than rubber.
• Metre Pack: One-metre length so you cut only what you need; no leftover drum.
• Multi-Use: Suited to water, air, vacuum and washer plumbing on a modified engine.
• Clean Finish: Smooth bore for consistent flow and tidy routing.
• Not For Fuel: For coolant, vacuum and air only — never fuel or oil.

For anyone replacing cracked vacuum and water lines on a modified engine.
