Engineered for both strength and protection, the Blue Heatshrink Butt Connector 4.0mm delivers a reliable solution for splicing and securing electrical wires. This connector features a dual-wall design with a heat-activated hot melt adhesive lining that seals the connection against moisture, dust, and corrosion.

With a shrinkable temperature range of +125°C to 180°C and an operating range from -45°C to +125°C, it is suitable for demanding environments, including automotive, marine, and outdoor applications. The low insertion force allows for straightforward installation, while the tin-plated copper conductor ensures high conductivity and corrosion resistance.

Rated for use in systems up to 600V, this connector offers long-term reliability and secure electrical performance.
