Stainless Steel 44" Flexible Heater Hose Kit - Black

• Flexible stainless steel hose routes coolant to and from the heater core

• Includes 5/8" and 3/4" adapters to match heater core and block/engine ports

• 44" length allows custom routing around firewall and engine bay obstructions

• Black finish with matching aluminum clamp covers for a coordinated look

This stainless steel flexible heater hose kit connects the heater core to the engine or block heater port, with flexible construction that allows custom routing around firewall and engine bay obstructions rather than following a fixed factory hose path. Two hoses are included at 44" length and 3/4" OD, along with four hose adapters — two at 5/8" and two at 3/4" — to match ports of different sizes on each end. A black finish and matching aluminum clamp covers give the installation a coordinated, finished appearance.

Confirm which adapter size matches your heater core port and which matches your engine or block heater port before routing, since the two ends of a hose run may use different adapter sizes. Hose clamps and clamp covers are included.

Port and Adapter Sizing
This kit includes two adapter sizes — 5/8" and 3/4" — since heater core and engine/block heater ports are often different diameters from each other. Confirm which adapter size matches your heater core port and which matches your engine or block port before routing.

Routing and Length
The 44" overall length and flexible stainless steel construction allow custom routing around engine bay obstructions rather than requiring a fixed hose path. Confirm this length provides enough slack for your specific firewall-to-block or firewall-to-intake routing before cutting or trimming.

Why are there two different adapter sizes included?
The kit includes both 5/8" and 3/4" adapters to accommodate different heater-core and engine-side connection sizes commonly found in heater-hose routing.

Are the two hoses in this kit the same length?
Yes — both hoses are 44" long, providing flexibility for custom routing between the engine and heater core.

Does this kit include hose clamps and clamp covers?
Yes — hose clamps and matching aluminum clamp covers are included, providing a cleaner finished appearance over exposed clamp hardware.

Is this available in other colors?
Yes — this heater hose kit is also available in blue and red finishes.

Can I cut this hose to a shorter length?
Yes — the 44" hoses can be trimmed for custom routing. Measure your complete routing path before cutting and leave enough length for secure adapter engagement and clamping.
