Key Features & Benefits – Aluminized insulated wire/hose heat shield sleeve with hook & loop closure 1.25"
The aluminized insulated wire/hose heat shield sleeve with hook & loop closure 1.25" (heat shield sleeve) is designed to reduce radiant heat exposure and protect the outer surface of wiring and hose runs in the engine bay.
It is functionally suitable for wire and hose bundles where the bundle OD fits within the 1.25" (31.75 mm) inner diameter. The lengthwise split and hook & loop edges allow quick installation without disconnecting the line or harness.
When is this useful?
It helps on sections routed near heat sources when you want heat shielding while keeping maintenance simple because the sleeve can be opened and re-closed.
Technical specs
- Design: Lengthwise split sleeve with hook & loop closure
- Inner diameter: 1.25" (31.75 mm)
- Length: 6 ft (182 cm)
- Surface: Aluminized outer layer
- Construction: Insulated
Selection & installation tips
- Diameter check: Measure the bundle OD at multiple points and allow a little clearance for vibration and movement.
- Length planning: Use the 6 ft length to cover the hottest zone fully, not just the midpoint of the run.
- Orientation: Keep the aluminized side facing outward toward the heat source for reflective shielding.
- End retention: Secure the ends so the sleeve cannot creep, open, or rotate under vibration.
- Routing & abrasion: Avoid sharp edges and constant rubbing; add extra mechanical protection where needed.
Before installation, verify bundle OD, required coverage length, and clearances, then match them to the 1.25" ID and 6 ft length listed above.
