3M Highland Vinyl-Insulated Ring Terminal, Standard Ring Tongue

3M Highland Vinyl-Insulated Ring Terminal, Standard Ring Tongue

The 3M Highland Vinyl-Insulated Ring Terminal family delivers dependable, code-compliant wire terminations for commercial, industrial, and general electrical installations. Available across four models — RV10-38Q, RV14-10Q, RV14-8Q, and RV18-8Q — this Highland series covers a range of AWG wire sizes and ring stud sizes, including the RV10-38Q's AWG 12-10 wire range with a 3/8" (0.375") stud. Every terminal in the family is built from tin-plated electrolytic copper with a color-coded vinyl insulation sleeve and a standard-style ring tongue that fits fully around the stud for a secure mechanical and electrical connection. Terminals are supplied 25 per bag and made in the USA, giving electricians, panel builders, OEM assemblers, and maintenance technicians a consistent, ready-to-stock ring terminal solution.

Key Features

• Wire Range Coverage: The Highland ring terminal family spans multiple AWG wire ranges, including AWG 12-10 on the RV10-38Q, so the correct terminal can be matched to the conductor size in use.
• Stud Size Options: Ring tongue sizes vary by model, with the RV10-38Q sized for a 3/8" (0.375") stud, seating fully around the stud rather than slipping underneath it.
• Durable Construction: Tin-plated electrolytic copper resists corrosion and oxidation while maintaining low-resistance, high-conductivity contact over the life of the connection.
• Vinyl Insulation: A color-coded vinyl sleeve identifies the wire range at a glance and shields the crimp barrel from abrasion and moisture.
• Standard-Style Ring Tongue: Full-circle ring design provides a secure mechanical hold that stands up to vibration and thermal cycling.
• Butted Barrel Construction: Barrel design is engineered for use with standard crimping tools to create a solid, low-resistance joint.
• Convenient Packaging: Supplied 25 terminals per bag for easy inventory control and stocking.
