Value Collection ZRNYDL5-4 Ring Terminal 12-10 Awg Crimp

Product Description

The VALUE COLLECTION ZRNYDL5-4 is a partially insulated circular ring terminal designed for crimp-style wire terminations in electrical and low-voltage wiring applications. It accepts 12 to 10 AWG wire (4.00 to 6.00 sq mm) and fits a size 8 stud. The copper contact provides reliable conductivity, while the yellow nylon partial insulation offers basic mechanical protection at the wire barrel entry. Overall length is 1.173 inches and ring width is 0.374 inches, making it a compact, standard-profile terminal suitable for panel wiring, control circuits, and equipment grounding connections.

This ring terminal is used in residential and light commercial electrical work, HVAC control wiring, panel terminations, and equipment harness assemblies. Electricians and HVAC technicians reach for this style of terminal when landing 12 or 10 AWG conductors on screw or bolt termination points in control boards, junction boxes, and motor connections. The size 8 stud fit is common in low-voltage control circuits and appliance wiring. The yellow color coding follows standard AWG wire range identification, helping technicians sort terminals quickly on the bench.

Key Features

• Partially insulated nylon sleeve protects the wire barrel entry point during and after crimping
• Copper contact material for solid electrical conductivity across the termination
• Accepts 12 to 10 AWG wire (4.00 to 6.00 sq mm) for versatile use across common wire sizes
• Fits size 8 stud (4.30 mm) — a widely used fastener size in control and appliance wiring
• Yellow color coding identifies the compatible AWG range at a glance
• Crimp connection type requires no soldering, enabling fast, repeatable terminations in the field

Compatibility

Designed as an OEM-style replacement or standard-stock ring terminal for use with 12 to 10 AWG conductors terminated on size 8 studs in electrical, HVAC, and light industrial wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians following NEC guidelines for wire termination and insulation. Always de-energize the circuit and verify zero voltage with a meter before landing or removing terminals. Use a calibrated ratcheting crimp tool sized for the AWG range to achieve a secure, gas-tight crimp — avoid pliers or uncalibrated tools that can produce an incomplete crimp. Inspect the nylon sleeve after crimping to confirm the conductor is fully seated and no bare wire is exposed beyond the barrel.
