Outus 1" ID Silicone Heater Hose 25ft Roll (Blue) — Reinforced High-Temp 85 PSI, Flexible

Outus 1" ID Silicone Heater Hose is a 25-foot reinforced silicone coil designed for engine cooling, heater lines, and high-temperature fluid transport in vehicles.

This reinforced silicone heater hose from Outus combines flexible handling with high-temperature durability for automotive cooling systems and related fluid-transfer needs. Supplied as a 25 ft roll, it lets you cut custom lengths for radiator connections, heater core runs, vacuum lines, or replacement sections. Built with a polyester braid reinforcement, the hose resists aging and cracking better than standard EPDM rubber while tolerating a broad temperature span and common coolant chemistries.

How does this hose perform under high temperatures and pressure?

The Outus silicone heater hose is engineered for sustained heat and working pressure seen in engine compartments. It operates across a wide temperature band and maintains integrity up to rated pressures for everyday automotive use.

• Temperature range: -40°F to 230°F (-40°C to 160°C) for consistent flexibility and performance.
• Working pressure: up to 85 PSI with a burst capability around 142 PSI for safety margins.
• Reinforced polyester braid reduces risk of bulging or splitting under load.

Will this hose fit my vehicle and installation needs?

This product is a universal, cut-to-fit solution intended for common 1" ID applications, making it adaptable across many models. The 25 mm inner diameter and supplied 25-foot length provide plenty of material for multiple runs or complex routing.

• Inner diameter: 1" (25 mm) and outer diameter: 33 mm for standard heater and radiator fittings.
• 25 ft coil allows custom cutting and multiple replacements from one roll.
• Flexible and kink-resistant for easier routing in tight engine bays.

What fluids and environments is the hose compatible with?

Outus silicone hose tolerates a range of thermal media and mild chemical exposures common in vehicle systems. It is suitable for coolant and hot water lines as well as air and low-concentration chemical uses.

• Recommended for coolant, hot water, air, and steam applications in vehicle systems.
• Resistant to weak acids and alkalis up to about 25% concentration.
• Compatible with common automotive coolants and many thermal fluids.

How easy is it to install and maintain?

Installation is straightforward: cut to length, secure with clamps, and route as needed. The silicone construction stays flexible over time, simplifying repairs and reducing the chance of brittle failures.

• Easy-to-cut coil for precise custom lengths and on-the-vehicle trimming.
• Seals reliably with standard hose clamps and fittings.
• Low maintenance—resists cracking and aging compared with EPDM under heat stress.

Who this product is for: Technicians, DIY mechanics, and fleet maintenance teams looking for a reliable, high-temperature replacement hose or a versatile coil for multiple repair jobs will find this Outus silicone heater hose useful. It’s especially suited to projects that require flexible routing, long runs cut-to-fit, or a hose material with improved heat and aging resistance versus traditional rubber hoses. Do not use where media compatibility or pressure requirements exceed the stated limits; always verify dimensions and clamp styles for your application.
