Raychem HFT5000 12/6 mm is a heat-shrinkable woven fabric tubing from TE Connectivity for abrasion protection on medium-sized harness branches. The 12/6 mm size slides over bundles up to 12 mm OD before recovery and grips down to a 6 mm minimum ID — suited for sub-looms, branches over a DR-25 jacketed run, and harness sections in high-abrasion zones such as gearbox tunnels.
The weave combines polyethylene (PE) for shrink force and polyester (PET) for abrasion resistance. Recovery temperature is low (80°C minimum), making it safe to apply over finished Tefzel wiring or an existing DR-25 jacket without heat damage.
HFT5000 is not a sealing product. The woven construction is porous — it does not seal against fluids. For wet-bay routing, use Raychem DR-25 as the primary sealed jacket underneath and HFT5000 over the top.

Typical motorsport applications
| Application | Notes |
|---|---|
| Sub-looms and branches (bundles 6–11 mm OD) | Standalone in dry zones; over DR-25 in wet zones |
| Gearbox tunnel harness routing | High-abrasion zone — use over DR-25 jacketed loom |
| Harness exits through bulkhead grommets | Protects against edge cut-through |
| Over DR-25 6/3 mm jacketed branches | Layered abrasion + sealing system |
Application
Recover at 80°C minimum; 140–190°C recommended for complete recovery. Move the heat gun continuously. HFT5000 shrinks approximately 10% in length during recovery — pre-cut lengths longer than the finished dimension.
Per metre: Each metre is one continuous cut length, hand-wound loose — not separate pieces.
Other sizes
- HFT5000 6/3 mm — for sensor pigtails and small branches up to 6 mm OD
- HFT5000 20/10 mm — for main trunks up to 20 mm OD
