Description

Raychem DR-25 3/8 Heat Shrink Tubing for Motorsport Wiring

The DR-25-3/8-0-UK is Raychem DR-25 cross-linked polyolefin 2:1 heat shrink tubing in 3/8 expanded inner diameter (approximately 9.5 mm expanded, recovering to approximately 3.8 mm), from TE Connectivity Raychem. DR-25 is a military and aerospace specification heat shrink tubing widely used in professional motorsport harness construction for its consistent quality, controlled shrink temperature, and long-term resistance to the motorsport environment. This diameter suits 8–14 AWG wires and small multi-conductor cable protection near moderate heat sources.

Raychem DR-25 — Military Specification Heat Shrink for Motorsport

DR-25 is manufactured to MIL-DTL-23053 specification and is one of the most widely specified heat shrink products in professional aerospace and motorsport harness work. Its cross-linked polyolefin construction provides continuous temperature resistance of 135°C, resistance to fuel, oil, coolant, and hydraulic fluid, and UV resistance for externally routed harness sections. The 2:1 shrink ratio suits the majority of individual wire and small connector insulation applications. In professional motorsport harness building, using Raychem DR-25 provides confidence in dimensional consistency and shrink behaviour that generic alternatives cannot match — particularly important when the shrink tubing must conform precisely to a connector body or splice joint to provide effective protection.

3/8 Diameter — Application Range

The 3/8 DR-25 suits 8–14 AWG wires and small multi-conductor cable protection near moderate heat sources. DR-25 is a single-wall (non-adhesive-lined) product, providing insulation and mechanical protection without the environmental sealing of the adhesive-lined SCL or ATUM products. It is used where insulation, chafe protection, or strain relief is required without the need for a waterproof seal at the application point.
