48" Flexible Radiator Hose Stainless Steel Universal Water Hoses Adapter Coolant Radiator

The iRKY 48-inch Flexible Radiator Hose Kit provides an adaptable coolant routing solution for custom engine bays and cooling system setups. It replaces traditional molded lines with a bendable metal design, making it ideal for vehicle builds where finding a factory rubber hose with the exact required bends is difficult.

Built from chrome-finished stainless steel, this hose offers strong heat resistance and will not rot or blow out over time like standard rubber hoses. The tubing can be bent directly by hand into the necessary shape and cut down to match your exact engine layout. The 48-inch length includes enough hardware ends to assemble two separate hose runs.

To ensure broad compatibility, the package includes four rubber sleeve adapters along with four sets of rubber reducers for 1-1/4-inch, 1-1/2-inch, and 1-5/8-inch radiator necks. Eight hose clamps and four chromed aluminum end cap covers are also supplied to secure each connection point cleanly.

Because the hose arrives as a single 48-inch section, you will need to measure and cut the metal tubing yourself if your configuration requires shorter lengths or two separate pieces. Radiator setups with neck sizes outside the listed 1-1/4, 1-1/2, or 1-5/8-inch sizes will not fit the included reducers.

Verdict: The iRKY flexible radiator hose kit is a practical choice for anyone needing a customizable, heat-resistant coolant line for 1-1/4, 1-1/2, or 1-5/8-inch radiator necks. It eliminates the guesswork of pre-shaped rubber hoses by letting you cut and bend the lines to fit your specific build.

• Hose Length: 48 inches
• Hose Material: Stainless steel with chrome finish
• End Cap Material: Chromed aluminum
• Compatible Radiator Neck Sizes: 1-1/4 inch, 1-1/2 inch, 1-5/8 inch
• Included Accessories: 8 hose clamps, 4 sleeve adapters, 12 rubber reducers, 4 end caps

A great fit if you:

• Need a custom-shaped coolant line and cannot find a pre-molded rubber hose.
• Want durable stainless steel tubing that resists heat and will not rot out.
• Are connecting to standard 1-1/4-inch, 1-1/2-inch, or 1-5/8-inch radiator necks.
• Need enough hardware to create up to two separate hose runs from a single kit.

Consider something else if you:

• Have radiator necks that are smaller than 1-1/4 inches or larger than 1-5/8 inches.
• Prefer a drop-in, direct-fit factory hose that requires no cutting or bending.

What radiator neck sizes are compatible with this kit?
The kit comes with rubber reducers designed to fit 1-1/4-inch, 1-1/2-inch, and 1-5/8-inch radiator necks.

Can I cut the hose to make more than one line?
Yes, the 48-inch hose can be cut to your required length. The package includes four end caps, clamps, and adapters, which is enough hardware to create two separate lengths of hose.

What components are included in the box?
The box includes one 48-inch stainless steel flexible hose, 8 hose clamps, 4 rubber sleeve adapters, 12 rubber reducers (four each for 1-1/4-inch, 1-1/2-inch, and 1-5/8-inch inner diameters), and 4 chromed aluminum end cap covers.
