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

iRKY's 48" stainless steel flexible radiator hose kit is a universal coolant hose replacement that bends, cuts, and adapts to most radiator necks for a durable, heat-resistant alternative to rubber hoses.

This complete 48-inch kit from iRKY replaces brittle rubber coolant lines with a flexible stainless steel solution designed for upper or lower radiator connections. The kit includes a full-length corrugated stainless hose that you can shape to fit the layout of your engine bay, plus clamps, rubber reducers, adapters, and chromed end caps to finish the installation neatly. Built to withstand heat and resist rot, these hoses are intended as a long-lasting mechanical replacement part rather than a consumable item.

How does the iRKY stainless hose handle high temperatures and aging?

The hose body is made from corrosion-resistant stainless steel which tolerates engine-bay heat and won’t degrade like standard rubber over time. Because it’s metallic and corrugated, it resists common failure modes such as softening, cracking, or rotting under heat and coolant exposure.

• Stainless steel construction for improved heat and corrosion resistance
• Corrugated/flexible design reduces stress from vibration and movement
• Rubber sleeves and reducers protect mating points from abrasion
• Chromed end caps provide a sealed, finished look

Will this hose fit my vehicle’s radiator necks?

The iRKY kit is designed to be a universal replacement and works with 1 1/4", 1 1/2", and 1 5/8" radiator necks using the included rubber reducers and sleeves. Because the stainless hose can be cut to length and bent by hand, it adapts to many routing configurations across cars, trucks, and custom builds.

• Includes rubber reducers sized for 1 1/4", 1 1/2", and 1 5/8" inner diameters
• Cut-to-length hose gives flexibility for different chassis and layouts
• Eight hose clamps secure connections for reliable sealing
• Universal fit approach reduces the need for model-specific hoses

How easy is installation and final trimming?

Installers can bend the corrugated hose into the desired shape without special tools and trim the 48" length to fit. The kit supplies all mating components—clamps, rubber sleeves/reducers, and chromed end caps—so you can complete the connection and finish the appearance of the hose without sourcing extras.

• Bendable stainless hose contours to engine bay geometry
• Cut-to-fit length lets you eliminate excess and make precise runs
• Supplied clamps and adapters simplify assembly and sealing
• Chromed caps snap or clamp in place for a clean look

What comes in the box and what should I inspect before use?

The kit ships with a 48" stainless flex hose, eight hose clamps, four rubber hose sleeve adapters, sets of rubber reducers for the three common neck diameters, and four chromed aluminum end caps. Before installing, confirm reducer sizes match your radiator neck and check clamps and sleeve pieces for correct fit to prevent leaks.

• 1x 48" stainless steel flexible hose (pre-braided/corrugated)
• 8x stainless hose clamps for secure connections
• 4x rubber sleeve adapters and rubber reducers (1-1/4", 1-1/2", 1-5/8")
• 4x chromed aluminum end caps to finish exposed ends

This kit is intended for mechanical cooling system replacement work; follow vehicle manufacturer procedures and use appropriate coolant and torque specs during installation. It is not a pressure-tested warranty substitute—inspect all connections after initial run and retighten clamps as required.

Who is this for: DIY mechanics, fabricators, and custom-build enthusiasts who want a corrosion-resistant, shapeable radiator hose to replace worn rubber lines or to tidy up custom coolant routing. It suits anyone needing a universal-length, cut-to-fit stainless option that includes the adapters and clamps to complete a neat, durable installation.
