Meonum 10ft 1/4" EPDM Heater Hose Kit — 1/4in ID Heat-Resistant Coolant Line with 4 Stainless Clamps

Meonum’s 10-foot 1/4" EPDM heater hose kit is a flexible, heat- and cold-resistant coolant line that includes four stainless steel clamps for leak-resistant heater and cooling system connections.

This 1/4" (≈6 mm ID) heater hose is engineered from EPDM rubber to withstand a wide temperature span and everyday automotive stresses. It’s supplied as a 10-foot length so you can cut it to fit heater cores, radiator overflow lines, or other small-diameter coolant paths. Four adjustable stainless clamps are included for a secure, professional installation without needing extra hardware.

How does this hose handle extreme temperatures and aging?

The EPDM compound resists cracking, hardening and ozone damage, so the hose retains flexibility from cold starts to hot operating conditions. It’s rated for temperatures from –40°F to +257°F (–40°C to +125°C), keeping shape and function across seasonal cycles. Built-in resistance to environmental aging extends service life compared with generic rubber lines.

• Material: automotive-grade EPDM rubber for heat, ozone and weather resistance.
• Temperature range: –40°F to +257°F (–40°C to +125°C).
• Designed to resist long-term hardening and surface cracking.

Will it fit my vehicle and what pressures can it handle?

The hose has a 1/4" inner diameter (≈6 mm) and 1/2" outer diameter (≈12 mm), suitable for many heater and small coolant lines on cars, SUVs, light trucks and equipment. Its working pressure is rated at 150 PSI with a burst pressure of 360 PSI, giving a wide safety margin for typical coolant system use. Measure your existing line and available routing before cutting the new hose to length.

• Internal diameter: 1/4" (≈6 mm); outer diameter: ≈1/2" (12 mm).
• Working pressure: 150 PSI; burst pressure: 360 PSI.
• 10-foot length provides room to trim for custom routing and repairs.

How easy is installation and what’s included in the kit?

The kit is intended for straightforward replacement or DIY repairs: cut the hose to the needed length, slide on the clamps, place the hose on the fittings and tighten. Four stainless steel adjustable clamps are supplied so you can secure multiple connections without buying extras. The hose’s flexibility and minimum bending radius simplify routing around tight components.

• Package includes one 10-foot 1/4" hose and four stainless adjustable hose clamps.
• Minimum bending radius: 152 mm for tight engine-bay routing.
• Cuttable length allows custom installation for heater cores or overflow lines.

What fluids and applications is it suitable for?

This line is formulated for water-based automotive fluids: coolant, antifreeze blends and plain water in non-lubricating systems. It is not designed for contact with petroleum-based engine oils. Typical uses include heater core lines, radiator overflow connections, small coolant return lines and general-purpose water-carrying plumbing on vehicles and light machinery.

• Compatible media: engine coolant, antifreeze, and water (non-oil automotive fluids).
• Common applications: heater core hoses, radiator overflow, cooling-system bypasses.
• Not recommended for oil or fuel systems.

Who is this for? Mechanics, restoration hobbyists, fleet maintenance teams and DIY vehicle owners who need a reliable, cut-to-fit small-diameter heater hose will find this Meonum kit practical. It’s aimed at anyone replacing brittle or leaking heater lines, fabricating custom coolant runs, or stocking a workshop with a straight-forward, durable EPDM hose and clamps. Verify diameter and routing before ordering to ensure the correct fit for your project.
