Package List: QH6015*20 Professional Wiring Kit includes 20 PCS JWS81824/1-3 Yellow Butt Contacts and 20 PCS JSS81824/1-3H High-Temp Heat Shrink Sleeves. Engineered for heavy-duty circuit joining.

[IP68 ULTIMATE ENVIRONMENTAL SEAL] 

Achieve a certified IP68 waterproof rating for your most critical connections. The polyolefin tubing, combined with internal EVA hot-melt adhesive, creates a permanent, hermetic barrier during heat application. This system effectively blocks moisture, fuel, and pressurized water, making it the definitive choice for exposed marine, automotive, and industrial electrical systems.

[M81824/1 STANDARD & THERMAL RESILIENCE] 

Elevate your engineering projects with components designed according to the M81824/1 standard. Capable of withstanding extreme thermal shifts from -55°C to 150°C (PVDF) or 125°C (PE), these sleeves provide exceptional structural integrity. It is the trusted solution for mission-critical defense, aviation electronics, and heavy-duty industrial machinery.

[PREMIUM METALLURGY & ANTI-CORROSION] 

The JWS81824 series is forged from 99.9% Pure Copper with an advanced Matte Tin plating process, ensuring maximum conductivity and resistance to 48H salt spray. Through a specific tempering treatment, the metal achieves a hardness of 35-55, ensuring the material remains ductile enough to prevent structural cracking after crimping for a permanent, high-tenacity link.

[PRECISION ALIGNMENT & SYSTEM ORGANIZATION] 

Specifically sized for 12-16 AWG (3.3-1.3mm²) conductors, each yellow contact features a built-in wire stop and inspection window for perfect conductor positioning. The specialized color band is designed to remain securely attached even after crimping, ensuring your circuits stay organized and identifiable in complex wire harnesses.

[MIL-SPEC PRECISION CRIMPING SYSTEM] 

For optimal mechanical and electrical performance, this kit is perfectly matched with the ACT-232 crimper (According to M22520/37-01). Featuring a high-carbon steel head with a hardness up to HRC 45-50, the tool’s 3-cavity die and high-precision ratchet ensure the consistency of every crimp, replacing unreliable soldering with a professional, gas-tight mechanical bond.
