Deray V25 3/4 (DR-25) Heat Shrink Tubing 19/9.5 mm

Deray V25 3/4″ is a flexible, thin-wall elastomeric heat shrink tubing with a 19 mm supplied inner diameter that recovers to 9.5 mm. It is a direct alternative to Raychem DR-25 3/4″, built to the same MIL-DTL-23053/16 elastomeric performance class, so it carries over the same fuel resistance, flame retardancy and −75°C to +150°C rating that motorsport and aerospace looms are specified around. At 19 mm supplied diameter it is the size for large main loom trunks and heavy chassis runs.

Specifications

Typical Use — 3/4″ (19 mm)

At 19 mm supplied diameter, this size covers:

• 25–50 wire main loom sections
• Full chassis trunk runs and engine main-harness backbones
• Large multi-pin connector pigtail bundles
• Outer jacketing where several sensor and power sub-branches merge

For 15–25 wire harness trunks, use Deray V25 1/2 (DR-25) 12.7/6.4 mm. For individual sensor leads and small branches, use Deray V25 3/16 (DR-25) 4.8/2.4 mm.

Deray V25 vs Raychem DR-25

Deray V25 is specified to the same MIL-DTL-23053/16 elastomeric class as Raychem DR-25 and is dimensionally interchangeable — the same supplied and recovered diameters, the same 2:1 shrink ratio, and the same −75°C to +150°C operating range. It installs identically and is suitable where a DR-25 alternative is acceptable. For the original part, see Raychem DR-25 3/4″ (19/9.5 mm).

Application

Slide the tubing over the harness bundle before terminating connectors, then recover with a heat gun at 150°C or above, working from the centre outward to drive air ahead of the shrink front. Once recovered it forms a tough, abrasion- and cut-resistant jacket that protects against mechanical, thermal and chemical damage in engine-bay and chassis routing.
