Hypertune 48" Stainless Steel Radiator Hose Kit — 1.6" OD Universal, Flexible & Corrosion-Resistant

Hypertune's 48-inch stainless steel universal radiator hose kit is a flexible, corrosion-resistant replacement coolant line that can be cut and fitted for upper or lower radiator necks.

This kit replaces conventional rubber radiator hoses with a pliable stainless steel braid and includes four end caps with rubber sleeves and clamps so you can shape, trim, and secure a custom-length coolant run. Built to resist rot and blowouts, the hose is designed to work with 1.6" radiator necks and arrives with adapters to fit common sizes. It’s a practical alternative when you need a durable, long-lasting hose that handles everyday engine bay conditions while offering a neat, metallic finish.

How do I fit this Hypertune hose to my vehicle?

Installation is straightforward if you follow the included steps: remove the old rubber hose, slide the supplied rubber sleeves onto one end of the new hose, bend the stainless braid to match the original hose path, trim excess length, and secure with the supplied end caps and clamps. No specialized tools are required beyond cutters and a screwdriver.

• Remove existing hose and clean connection points.
• Slide rubber sleeve adapters onto the new hose before attaching caps.
• Shape hose against the factory routing, then cut to length.
• Tighten end caps and clamps, adjusting screw tightness to prevent leaks.

Will this fit my radiator neck and coolant system?

The Hypertune hose is a universal-style 48" stainless braid with an outer diameter of 1.6" and inner diameter 1.2", intended to work with 1.6" radiator necks. The kit includes three rubber reducer sizes and adapter sleeves to accommodate small variances in connection diameters, so it will fit many domestic and import cooling setups when trimmed to length.

• Hose dimensions: 48" length, 1.6" O.D., 1.2" I.D.
• Adapters: multiple rubber reducers included for 1.2"–2.0" ranges.
• Caps: aluminum end caps with screw-tighten clamps for secure sealing.
• Designed for upper or lower radiator hose replacement when cut to fit.

What are the material benefits and long-term reliability?

Constructed from stainless steel braid with aluminum end caps and rubber sleeves, this hose resists the common failure modes of rubber hoses such as rot, swelling, and sudden blowout. Its flexible design allows easy shaping to existing engine bay pathways while providing greater abrasion and heat resistance than standard rubber. Expect improved longevity and a cleaner engine-bay appearance.

• Stainless braid resists corrosion and cracking compared to rubber.
• Aluminum caps provide firm clamping and long-term durability.
• Rubber sleeves protect mating surfaces and ensure a tighter seal.
• Flexible construction reduces the need to source exact-angle rubber hoses.

How should I maintain the Hypertune stainless hose after installation?

Routine visual checks are sufficient—inspect clamps, end caps, and sleeves for tightness and any signs of wear. Clean the exterior occasionally to remove oil and grime that can hide early wear, and retighten clamps if you detect seepage after initial heat cycles.

• Check clamp tightness after first few heat cycles.
• Wipe down braid to keep grime from accumulating.
• Replace rubber adapters if they show excessive aging or cracks.

Who is this for: The Hypertune Universal 48" Stainless Steel Radiator Hose Kit is aimed at DIY mechanics, tuners, and vehicle owners seeking a more durable, customizable radiator hose than stock rubber options. It’s ideal if you need a hose that resists rot and blowouts, want the freedom to trim and shape a single hose for upper or lower radiator routing, or prefer a stainless-finish look in the engine bay. Check the kit dimensions and your radiator neck size before purchase to ensure compatibility.
