SATUGUOJI 5/8" (16mm) Silicone Heater Hose Kit — 5 ft Red with 5 Clamps, High-Temp Reinforced

SATUGUOJI's 5/8" (16mm) high-temp silicone heater hose kit is a reinforced, 5-foot red coolant line with five clamps built to replace old heater or coolant hoses in engines and water-cooled equipment.

When your vehicle or equipment needs a durable replacement for brittle or leaking heater and coolant lines, this SATUGUOJI kit provides a ready-to-fit hose designed for high temperatures and pressure. The 4mm-thick wall and polyester-braid reinforcement add mechanical strength, while the dual silicone layers resist heat, ozone, and aging. The kit is sized for 5/8" (16mm) inner diameter fittings and includes five stainless-style clamps so you can measure, cut, install, and secure a dependable connection right away.

What temperatures and pressures can this hose handle?

The SATUGUOJI silicone heater hose is engineered for demanding thermal and pressure conditions typical in engine bays and hot-water systems. It performs across a wide temperature range and maintains integrity under sustained system pressures.

• Operating temperature: -4°F to 428°F (-20°C to 220°C)
• Working pressure: up to 60 PSI under normal conditions
• Burst pressure: tested to 232 PSI for safety margin
• Reinforced design reduces expansion and blowout risk

How durable is the hose compared with standard rubber lines?

This silicone assembly offers improved resistance to heat, ozone, and oil exposure versus many OEM rubber hoses. The 4mm wall thickness plus an embedded polyester braid provides extra abrasion and crush resistance for longer service life.

• Thick dual silicone layers protect inner core and resist cracking
• Polyester-braid reinforcement increases tensile strength
• Less permeability than older rubber hoses—fewer leaks over time
• Color-stable red finish helps spot check for wear or damage

Will this fit my car, motorcycle, or generator?

The kit is made for systems that use a 5/8" (16mm) inner-diameter heater or coolant connection. It’s compatible with many automotive, motorcycle, ATV, generator, and water-cooled equipment lines, but you should confirm the connection size before installing.

• Inner diameter: 5/8" (16mm)
• Length: 5 feet (cut-to-fit for custom routing)
• Includes five clamps for secure attachment to fittings
• Suitable for both coolant and hot-water circulation lines

How easy is it to install and maintain?

Installation is straightforward: measure the run, cut the hose to length, push onto the barb or spigot, and tighten the supplied clamps. Routine inspection and clamp re-tightening are typically all that’s needed to maintain performance.

• Cut-to-fit 5 ft length simplifies custom installations
• Included clamps remove the need for separate hardware purchases
• Silicone resists scaling and hardening—less frequent replacement
• Inspect clamps and ends periodically for leak prevention

Who is this for: The SATUGUOJI 5/8" silicone heater hose kit is aimed at DIY mechanics, restoration shops, and equipment owners who need a dependable, heat-resistant replacement line for cooling and heater circuits. It’s particularly useful when upgrading from aged rubber hoses or when a longer-lasting, reinforced hose is desired for higher-temperature or higher-vibration applications. Always verify your connector dimensions and system compatibility before purchase.
