Copper Wire Connector Manufacturer Overview
What is a UR2 connector?
A UR2 connector is a red gel-filled IDC splice connector used to join two or three supported solid copper telephone wires without stripping the insulation. During crimping, the IDC contact cuts through the wire insulation and makes electrical contact with the conductor, while the gel helps reduce moisture exposure around the splice area. UR2 belongs to the same red connector family as UR. Buyers usually choose UR2 when the application requires a red 2-wire or 3-wire connector and the wire insulation outside diameter is larger than the compact UR format can support.

Installation
UR2 connector installation steps
UR2 connectors are installed by inserting two or three supported solid copper wires into the connector ports and crimping the red cap with a compatible crimping tool or suitable parallel-jaw pliers. No wire stripping, soldering, heat shrink, or tape is required for supported wire sizes.
- Prepare the wire ends: cut the solid copper wires with clean, square ends. Do not strip the insulation.
- Insert the wires: push each wire fully into the UR2 connector ports until they bottom out.
- Confirm wire count: use UR2 for supported 2-wire or 3-wire splice requirements.
- Crimp the connector: press the red cap evenly until the connector is fully seated.
- Check the splice: confirm that the cap is closed and all wires are held firmly.
- Tool note: compatible crimping tools can be discussed for bulk or project orders.
Model comparison
UR2 compared with UR and UY2 connectors
Buyers often compare UR2 with UR and UY2 because the three models cover the most common choice points around connector color, wire count, and maximum insulation diameter. UR2 and UR are both red connectors for 2-wire or 3-wire splice requirements, but UR2 supports a larger maximum insulation outside diameter. UR2 and UY2 share the same 0.4-0.9 mm wire range and 2.08 mm maximum insulation O.D., but UY2 is yellow and supports 2-wire splice work only.
- Choose UR2: red 2-wire or 3-wire splice where the maximum insulation O.D. requirement is up to 2.08 mm.
- Choose UR: red 2-wire or 3-wire splice where the maximum insulation O.D. requirement is up to 1.52 mm.
- Choose UY2: yellow 2-wire splice when the project requires a yellow connector format.
| Parameter | UR2 | UR | UY2 |
|---|---|---|---|
| Color | Red | Red | Yellow |
| Wire count | 2-wire or 3-wire | 2-wire or 3-wire | 2-wire |
| Wire range | 0.4-0.9 mm / 26-19 AWG | 0.4-0.9 mm / 26-19 AWG | 0.4-0.9 mm / 26-19 AWG |
| Max insulation O.D. | 2.08 mm | 1.52 mm | 2.08 mm |
| Blade/contact | Dual IDC contact | Dual IDC contact | Single IDC contact |
| Typical use | Red connector for 2-wire or 3-wire requirements with larger insulation diameter | Red connector for repair and tap splice work with smaller insulation diameter | Yellow 2-wire splice for larger wire or insulation diameter requirements |

Selection guide
When to choose UR2
Choose UR2 when the project requires a red gel-filled IDC connector for supported 2-wire or 3-wire copper telephone wire splice work and the insulation outside diameter requirement is larger than the compact UR format. UR2 is commonly selected when a buyer specification, drawing, inventory code, or maintenance system calls for the UR2 red connector format.
- The wire size is within 0.4-0.9 mm / 26-19 AWG.
- The maximum insulation outside diameter requirement is up to 2.08 mm.
- The splice requires two or three supported solid copper wires.
- The buyer specification, drawing, or inventory code calls for UR2.
- The project requires a red connector for field repair or tap splice work with larger insulation diameter.
- UR2 is already the model used in the existing telecom maintenance system.
