EZPROIT 48" Stainless Steel Flexible Radiator Hose Kit — 1.2" I.D., universal adapters for 1-1/4"•1-1/2"•1-5/8", clamps & caps

EZPROIT's 48" stainless steel flexible radiator hose kit is a universal replacement that lets you shape and secure a durable coolant line for engines with 1-1/4", 1-1/2" or 1-5/8" necks.

Designed as a heavy-duty alternative to brittle rubber hoses, this complete assembly gives mechanics, restorers, and DIY vehicle owners a corrosion-resistant, heat-tolerant coolant hose option that can be trimmed and adapted to fit many radiator-to-engine runs. The kit includes a 48-inch stainless flex hose with a 1.2" inner diameter, multiple rubber reducers/adapters, end caps and clamps so you can tailor the connection to common radiator neck sizes without custom fabrication.

How does this flexible stainless hose replace brittle rubber lines?

The braided stainless construction resists cracking, rotting and heat degradation that shortens rubber hose life. You cut the long flex hose to your required length and use the included rubber reducers and clamps to match radiator and engine neck dimensions for a sealed connection.

• 48" long stainless braided hose with 1.2" I.D. that can be trimmed to fit.
• Multiple rubber reducers for 1-1/4", 1-1/2" and 1-5/8" neck compatibility.
• Eight clamps and four end caps to secure and finish connections.

What tools and steps are needed to install the kit?

Installation is straightforward and requires basic hand tools: a cutter to trim the hose, screwdrivers or a nut driver to tighten clamps, and a quick trial fit of adapters. The kit ships with the parts to adapt common neck sizes so no special fittings should be necessary for many projects.

• Remove the old rubber hose and clean mating surfaces.
• Shape and cut the stainless hose to length, then slide on the reducer and clamp.
• Secure clamps at both ends, press on end caps where needed, and leak-test the system.

Will this fit my radiator and engine necks?

This EZPROIT kit was built for universal fitment across the most common neck diameters: 1-1/4", 1-1/2" and 1-5/8". The provided rubber adapters allow you to bridge the 1.2" hose interior to those neck sizes, but always verify physical clearance and alignment before cutting the hose.

• Adapters included for 1-1/4", 1-1/2" and 1-5/8" necks (for neck and hose).
• Flexible braid allows custom bends without kinking.
• Suitable for many universal, custom and restored vehicle applications.

How durable and safe is the stainless steel braided design?

Stainless steel offers superior resistance to heat and corrosion compared with standard rubber coolant lines; it won’t rot or crack from age and keeps its shape under pressure when properly installed. The inner liner and rubber adapters maintain a reliable seal without introducing hard-to-fit metal-to-neck contact points.

• High-quality stainless braid resists corrosion and heat exposure.
• Rubber reducers protect mating surfaces and ensure leak-free joins.
• Clamps and end caps finish connections for long-lasting performance.

Who is this for? The EZPROIT 48" stainless steel flexible radiator hose kit is aimed at car and truck enthusiasts, mechanics, and DIYers who need a robust, adjustable coolant line for engine swaps, custom plumbing or replacing failing rubber hoses. It’s particularly well suited for projects where routing needs nonstandard bends or where longevity and resistance to heat and aging are priorities. Verify hose inner-diameter and neck sizes before trimming, and always perform a pressure or road test after installation to confirm a secure, leak-free system.
