3M Scotchlok 316 IR Gel-Filled Wire Connector, 3-Port, 0.5-1.5 mm²

The 3M Scotchlok 316 IR is a professional-grade, gel-filled wire connector engineered for secure and reliable electrical connections in low-voltage systems. Designed to accommodate up to three wires with cross-sections between 0.5 and 1.5 mm², this connector features an integrated sealant that encapsulates the connection, providing robust protection against moisture, humidity, and corrosion. Its compact design and ease of use make it an essential component for maintaining electrical integrity in challenging environments.

Advantages

The primary benefit of the 3M Scotchlok 316 IR is its superior environmental protection provided by the internal silicone-based gel. This sealant prevents oxidation and moisture ingress, which are common causes of connection failure in outdoor or damp locations. The connector is designed for quick and efficient installation without the need for stripping wires, significantly reducing labor time. Its durable construction ensures a long-lasting, maintenance-free connection that remains stable even under varying temperature conditions.

Suitable for

• Outdoor lighting systems
• Irrigation control wiring
• Low-voltage landscape lighting
• Automotive and marine electrical repairs
• Humid or underground junction boxes

When it may not be suitable

This connector is specifically engineered for low-voltage applications and should not be used for high-voltage mains power installations. It is also not intended for use with wire gauges outside the specified 0.5 to 1.5 mm² range, as this may compromise the mechanical grip and the effectiveness of the moisture seal.

Key specifications

• Capacity: 3 ports
• Wire range: 0.5 to 1.5 mm²
• Protection: Integrated moisture-resistant gel sealant
• Application: Low-voltage electrical connections

How to use

To use the 3M Scotchlok 316 IR, insert the unstripped wires into the connector ports until they are fully seated. Ensure that the wires are pushed in as far as possible to allow the internal contact elements to pierce the insulation and establish a solid electrical connection. Once the wires are inserted, use a standard pair of pliers to compress the cap of the connector firmly until it locks into place. The compression action forces the gel around the connection, creating a sealed environment that protects the wires from external elements.

What to consider before purchase

• Verify that your wire cross-section falls within the 0.5 to 1.5 mm² range.
• Ensure the application is strictly for low-voltage systems.
• Check the number of wires to be connected to ensure the 3-port capacity is sufficient.

Usage recommendations: For optimal performance, ensure the wires are clean and free of debris before insertion. Always use proper pliers for compression to ensure the connector is fully closed and the gel is properly distributed around the connection point.
