Product Description

40mm PE Black Heat Shrink - 1M

Insulate high-power electronics, bundle complex wiring arrays, and shield structural components with the RMRC Premium 40mm PE Black Heat Shrink. Sold in convenient 1-meter (approx. 3.3 feet) sections, this heavy-duty Polyethylene (PE) tubing features a large ~41.5mm starting diameter, making it the perfect size for sliding over wide electronic speed controllers (ESCs), multi-wire distribution looms, or parallel power extensions. Once activated with a heat gun, it uniformly conforms down to provide a rugged, clean, and professional layer of insulation that defends sensitive hardware against abrasion, moisture, and debris.

This industrial-grade heat shrink handles severe mechanical demands across numerous technical fields. In the RC hobby and FPV market, its generous diameter is a staple for encasing large multirotor or fixed-wing ESCs, stabilizing thick multi-cell battery solder points, and creating resilient wire harnesses along drone arms. For the educational and STEM robotics market, these 1-meter strips serve as a foundational workbench material, allowing students to practice safe insulation techniques and manage clean, snag-free wiring channels on custom mechanical rigs. For sUAS contractors, enterprise aerospace developers, and government operations, this standardized PE tubing provides a highly repeatable and cost-effective solution for finalizing payload breakouts, applying uniform environmental protection to surrogate flightline hardware, or color-coding critical power busses.

Tech Tip: Avoid applying concentrated high heat to a single spot for too long. Use a sweeping motion with a professional heat gun to achieve a completely smooth, wrinkle-free finish with a consistent ~1.0mm wall thickness.

Key Features:

• Large ~41.5mm Starting Diameter: Easily slides over massive wire bundles, specialized telemetry modules, power distribution joints, and high-amp speed controllers.

• Premium Polyethylene (PE) Construction: Delivers robust electrical insulation and reliable puncture resistance under intense mechanical stress and vibration.

• Thick Protective Wall Profile: Shrinks down to form a durable ~1.0mm barrier, providing excellent long-term strain relief for heavy-gauge power lines.

• Continuous 1-Meter Length: Gives you the flexibility to cut custom-length sleeves down to the exact millimeter, eliminating component waste.

• Sleek Matte Black Finish: Conceals colorful internal wires and exposed solder joints for a clean, uniform look inside your airframe or ground equipment.

Recommended Items & Needed to Complete (Available at ReadyMadeRC): To complete your wiring protection and workbench setup, consider pairing this heat shrink with these current options from ReadyMadeRC:

• Alternative Sizes: Keep a complete repair arsenal on hand with smaller diameters like the 10mm, 20mm, or 30mm PE Black Heat Shrink variants.

• Translucent Tracking: Opt for the 45mm or 50mm PE Translucent Heat Shrink if you need to keep internal diagnostic LEDs or labels visible after sealing.

• Heavy-Duty Power Lines: Perfect for cleanly insulating cuts on thick-gauge power cables like the RMRC Premium Silicone Wire 12 Gauge.

• Electrical Bench Safeguards: Always integrate a safety tool like the TBS Smoke Stopper with XT60 and XT30 Plugs to check your circuits before applying final heat wrap.
