Home improvement and vehicle maintenance parts that promise reinforced durability for heater and coolant lines. For anyone replacing cracked or soft hoses, peace of mind comes from a component rated for extreme temperatures and accurate sizing. Does the AP Automotive Silicone Heater Radiator Hose meet workshop standards for fit and longevity?
⚡ At a Glance
- • Temperature Resistance: Wide operating range from -60°C to +180°C
- • Best for: DIY mechanics and workshops replacing heater or radiator hoses
- • Not ideal for: Systems requiring a different internal diameter or pre-fitted connectors
16mm internal diameter, one metre length, 4mm wall thickness with 2-ply polyester reinforcement. Suitable for heater, radiator, coolant, water, oil and diesel applications.
Secure connections - with a precise 16mm internal diameter
The bore measures 16mm internal diameter, manufactured to consistent tolerances for clamp seating. Accurate sizing reduces movement at hose ends and promotes even compression from hose clamps.
Snug clamping reduces the risk of leaks during normal use and makes installation straightforward for common heater and radiator fittings.
High thermal resilience - thanks to a wide operating temperature range
Rated from -60°C to +180°C, the silicone compound resists softening, hardening and brittle failure across extreme conditions. Thermal stability helps maintain flexibility in cold and pressure resistance in heat.
Suitable for systems exposed to rapid temperature changes, maintaining shape and function where standard rubber hoses might fail.
Longer service life - with 2-ply polyester reinforcement and 4mm wall
Two layers of polyester reinforcement embedded in the silicone wall increase tensile strength and dimensional stability. A 4mm wall thickness adds mechanical protection against abrasion and kinking.
Reinforced construction means fewer replacements and better resistance to wear in demanding heater, coolant and oil lines.
