iRKY 48" Stainless Steel Flexible Radiator Hose Kit — 48in Universal Coolant Line with Reducers & Chrome Caps

This all-in-one coolant hose solution from iRKY combines corrosion-resistant stainless steel construction with rubber adapters and chrome end caps to create a customizable, long-lasting replacement for worn or awkwardly routed rubber hoses. The kit arrives complete with clamps, rubber sleeves and multiple reducer sizes so you can trim and shape the hose to match your vehicle’s layout without hunting for several different parts.

How does the iRKY hose simplify fitting unusual engine layouts?

The hose’s flexible stainless braid can be bent by hand to follow tight or irregular paths where pre-formed rubber hoses would kink or require complex joins. Because the tube is continuous, you reduce the number of connections and potential leak points.

• 48" stainless steel hose that can be cut to length for custom routing
• Hand-bendable braid holds shape to avoid kinks
• Multiple rubber reducers (1¼", 1½", 1⅝") for common radiator neck sizes

What parts come in the kit and why do they matter?

The kit includes everything needed to make a secure coolant connection: the flexible hose, hose clamps, rubber reducers and chromed aluminum end caps for a finished appearance. These components mean you won’t need additional trips to the parts store to adapt to different inlet diameters.

• One 48" stainless steel flex hose ready to cut and shape
• Eight hose clamps to secure connections along the length
• Four rubber reducers in three sizes to fit varied radiator necks
• Four chromed end caps for a professional, sealed look

Is stainless steel better than rubber for radiator hoses?

Stainless steel braid resists heat, abrasion and aging far better than conventional rubber, helping the hose maintain integrity under prolonged exposure to hot coolant and engine bay conditions. Unlike rubber, the metal braid won’t soften, collapse, or rot over time, extending the usable life of your coolant line when properly installed.

• Improved heat and abrasion resistance compared to rubber
• Less prone to swelling, cracking or collapsing with age
• Corrosion-resistant finish for longer service life

How difficult is installation for a DIY mechanic?

Installation is straightforward: measure and trim the hose to the required length, slide on the appropriate rubber reducer, position clamps and tighten. No special tools are needed beyond common hand tools and a sharp cutter for the hose if shortening is required.

• Trim the 48" tube to the exact routing length you need
• Use included rubber sleeves and clamps for secure seals
• Hand-bend the braid to match bends—no heat forming required

Who this kit is for: The iRKY 48" Stainless Steel Flexible Radiator Hose Kit is suited to hobbyists, restoration projects, custom builds and anyone replacing failed rubber lines who wants a durable, adaptable alternative. It’s ideal when stock hoses won’t reach, when routing is tight, or when you want a cleaner, longer-lasting coolant connection without fabricating a custom metal pipe.
