Product Details

Features

  • Flexible stainless steel hose connects the radiator to the water pump or block
  • Includes three adapter sizes to match different radiator neck and outlet diameters
  • 48" length for longer routing paths; 12", 24", and 36" lengths also available
  • Sold without end caps — confirm your port connections before ordering

Description

This polished stainless steel flexible radiator hose kit connects the radiator to the water pump or engine block outlet, with flexible construction that allows custom routing around engine bay obstructions rather than following a fixed factory hose shape. This is the 48" length — the longest in this lineup; three adapter sizes are included — 1 1/4", 1 1/2", and 1 5/8", two of each — to match radiator necks and outlet ports of different diameters.

This kit is sold without end caps. Confirm whether your application connects directly to threaded or barbed ports without additional caps, or whether a separate end cap kit is needed before ordering. Hose clamps are included; a hose clamp cover is not.


Port and Adapter Sizing
This kit includes three adapter sizes — 1 1/4", 1 1/2", and 1 5/8" — since radiator necks and water pump/block outlets are often different diameters from each other. Confirm which size matches your radiator neck and which matches your water pump or block outlet before routing, since the two ends of your installation may need different adapter sizes.

Choosing a Length
This is the 48" version, suited to the longest routing distances in this lineup between the radiator and engine. Confirm this length provides enough slack for your specific routing path before cutting or trimming — shorter lengths (12", 24", 36") are available if less distance is needed.

Q&A

Does this kit include end caps?
No. This kit is sold without end caps — confirm whether your application connects directly to threaded or barbed ports, or requires a separately sourced end cap kit.

Why are there three different adapter sizes included?
Radiator necks and water pump/block outlets are often different diameters, so this kit includes 1 1/4", 1 1/2", and 1 5/8" adapters — two of each — to match both ends of your routing path.

What length should I choose?
Choose based on the distance between your radiator and water pump or block outlet — this 48" version suits the longest routing paths in this lineup; 12", 24", and 36" lengths are available for shorter needs.

Does this kit include hose clamps?
Yes, hose clamps are included. A hose clamp cover is not included.

Can I cut this hose to a shorter length?
The listed length is provided for custom routing flexibility — confirm your specific routing path's required length before cutting.
