25mm PE Black Heat Shrink - 1M
by RMRC

Insulate intermediate electronics, bundle multi-wire harnesses, and protect vital structural points from field friction with the RMRC Premium 25mm PE Black Heat Shrink. Sold in continuous 1-meter (approx. 3.3 feet) segments, this durable Polyethylene (PE) sleeve arrives with a pre-shrunk internal diameter of approximately 26.5mm. It is perfectly sized to clear standard electronic speed controllers (ESCs), mid-sized video transmitters (VTX), or heavy battery line intersections. When heat is evenly applied, it contracts down uniformly to encase your components in a rugged layer of defense that shields against dirt, moisture cuts, and accidental frame grounding.

This mid-diameter protective sleeve serves a vital structural role across different build spaces and payload configurations. In the RC hobby and FPV market, it acts as an absolute necessity for wrapping individual mini drone ESCs along carbon fiber arms, neatening multi-cable servo looms, or weather-stripping custom auxiliary BEC modules. For the educational and STEM robotics market, this 1-meter bench stock serves as an accessible teaching tool for instructing students on uniform wire management and the importance of solid electrical isolation on custom-machined chassis rails. For sUAS contractors, enterprise drone integrators, and government testbed programs, this standardized PE heat shrink functions as a dependable, highly repeatable benchmarking utility—ideal for sealing bespoke diagnostic breakout junctions, protecting surrogate sensory wire setups, or finalizing rugged component layouts before deployment.

Tech Tip: For optimal results, use a sweeping motion with a variable-temperature heat gun to ensure uniform contraction down to its minimum resting state. This method produces a smooth finish with an insulated wall thickness of approximately 0.9mm.

Key Features:

• Versatile ~26.5mm Pre-Shrunk Open Profile: Slides smoothly over multi-wire bundles, parallel battery splices, and compact multirotor or fixed-wing accessories.

• Premium Polyethylene (PE) Formulation: Provides robust dielectric isolation and notable puncture resistance under continuous flight stress and airframe vibration.

• Tough Post-Shrunk Thickness: Contracts down to a stable ~0.9mm wall profile, providing continuous strain relief at flexible cable boundaries.

• Continuous 1-Meter Segment: Allows builders to measure and slice custom sleeves to the exact millimeter needed, optimizing workspace efficiency.

• Professional Opaque Black Finish: Cleanly masks contrasting wire colors and complex solder unions to provide a sleek, uniform aesthetic inside any chassis bay.
