3M 316-IR Displacement Connector PK30

The 3M 316-IR is a gel-filled insulation displacement connector designed for electrical and automotive wiring tasks. It accepts both run and tap wires from 22 AWG to 16 AWG with a maximum insulation diameter of .155 in. Each connector provides three ports for quick, tool-free splicing. The pack contains 30 pieces for multiple installations.

600 V rating and 22-16 AWG wire range

Rated for up to 600 V, these connectors handle typical low-voltage automotive and industrial circuits. The three-port design accommodates pigtail splices within the specified wire gauge range. They are not suited for conductors larger than 16 AWG or for applications exceeding the 600 V limit. The .155 in maximum insulation diameter restricts use with thicker jacketed cables.

Moisture-resistant gel and 221 °F temperature rating

The nylon housing is filled with a moisture-resistant gel that seals the connection against water and contaminants. Brass contacts with a tin finish ensure reliable conductivity. The assembly is rated for a maximum operating temperature of 221 °F, making it suitable for engine-bay and under-hood environments. The 6.500 length fits standard splice locations.

Questions about this item

Will the 316-IR connector accept the 22-16 AWG wires I already have in my harness?

Yes, it is rated for both run and tap wires from 22 AWG up to 16 AWG with insulation diameters up to 0.155 inches.

How can I confirm the 316-IR displacement connectors made proper contact after installation?

The insulation-displacement design cuts through insulation when fully pressed; a firm tug on each wire and a visual check that the wire sits flush in the port confirm a solid connection.

Does the PK30 bag include any crimp tools or extra gel, or just the 30 connectors?

The pack contains 30 black-and-white nylon 316-IR connectors only; installation tools and additional sealant are sold separately.
