Why Choose the Partex BF66/08/VR Blue Push-On Terminals?
The Partex BF66/08/VR Blue Push-On Terminals are female electrical crimp connectors designed for quick, convenient connections to compatible 6.3 mm × 0.8 mm male spade terminals. Supplied in a practical pack of 100, these push-on connectors are suitable for electrical panel building, industrial machinery wiring, equipment maintenance and general electrical assembly work.
Featuring blue insulation and a push-on receptacle design, the Partex BF66/08/VR provides a convenient alternative to screw-terminal connections where equipment is fitted with matching male tabs. The crimp connection allows a suitably sized conductor to be terminated without soldering, while the push-on interface enables straightforward connection and disconnection during installation or servicing.
The 6.3 mm × 0.8 mm connection size is widely used for electrical equipment connections, making this type of terminal useful for compatible switches, relays, contactors, indicator assemblies and other components with matching tab terminals.
Manufactured by Partex, the BF66/08/VR is an economical and practical wiring accessory for professional electricians, electrical panel manufacturers, maintenance engineers and OEM equipment builders requiring consistent terminal connections across multiple installations.

6.3 mm × 0.8 mm Female Spade Connection
The Partex BF66/08/VR is designed for connection to a male spade tab measuring 6.3 mm wide and 0.8 mm thick.
Correct mating terminal dimensions are essential for a reliable push-on connection. The female receptacle must provide sufficient mechanical retention and electrical contact pressure when fitted to the male tab.
A connector that is too large may produce a loose connection, while an undersized connector may be difficult to install or may damage the mating terminal.
The BF66/08/VR should therefore be used with a compatible 6.3 mm × 0.8 mm male terminal rather than a smaller 4.8 mm or 2.8 mm tab.
Where equipment requires a different terminal width or thickness, the appropriate alternative connector should be selected.
Blue Insulation for Clear Identification
The blue insulation helps distinguish the Partex BF66/08/VR from terminals with red, yellow or other insulation colours.
In many insulated crimp-terminal systems, blue is commonly associated with conductors in the 1.5–2.5 mm² range. However, manufacturers may use different colour conventions or specify different conductor capacities for particular terminal designs.
The exact conductor range for the BF66/08/VR should therefore be checked against the Partex technical specification before installation.
The correct conductor size is essential for proper crimp formation. A conductor that is too small may not be securely retained, while one that is too large may prevent the terminal from being crimped correctly.
Insulation colour should be treated as an identification aid rather than a substitute for checking the product's electrical and mechanical specifications.
Secure Crimp Termination Without Soldering
The Partex BF66/08/VR uses a crimp termination to attach the connector to a suitable electrical conductor.
Crimping creates a mechanical and electrical connection by compressing the terminal barrel around the prepared conductor using an appropriate crimping tool.
When performed correctly, this method provides a repeatable connection without requiring solder.
For installation, the conductor should be stripped to the correct length, taking care not to damage the copper strands. The prepared conductor is then inserted fully into the terminal's crimp barrel.
The appropriate crimping die should be selected for the terminal and conductor size. After crimping, the connection should be visually inspected and checked for secure conductor retention.
The completed female receptacle can then be pushed onto a matching 6.3 mm × 0.8 mm male spade terminal.
Only suitably trained personnel should make electrical connections, and the relevant circuit must be safely isolated before installation or removal.
Quick-Disconnect Convenience for Equipment Wiring
Push-on terminals are commonly used where electrical components must be connected efficiently during assembly or disconnected during servicing.
Unlike a screw-terminal connection, a female push-on receptacle fits directly onto a compatible male tab without requiring the installer to tighten a screw at the component connection point.
This makes the Partex BF66/08/VR useful for repetitive wiring operations and equipment fitted with standard male spade connections.
The quick-disconnect format can also simplify replacement of compatible electrical components because the existing female connector can be removed from the component's male tab after the circuit has been safely isolated.
However, push-on connections must be correctly matched and fully seated. They should not be used where the mechanical environment, current rating or equipment specification requires a different connection method.
Insulated and Fully Insulated Push-On Terminals Compared
When choosing electrical push-on connectors, it is important to distinguish between insulated and fully insulated receptacle designs.
An insulated push-on terminal generally includes an insulating sleeve around the conductor crimp area, while the female receptacle may remain partially exposed.
A fully insulated terminal provides additional insulating coverage around the mating receptacle.
The Partex BF66/08/VR is described as a blue push-on terminal, rather than explicitly as a fully insulated variant. Installers should therefore confirm the actual insulation coverage before selecting it for applications requiring a fully enclosed receptacle.
Where full insulation around the mating connection is required, a specifically designated fully insulated Partex terminal should be selected.
Neither design replaces the need for suitable equipment enclosures and other protective measures required by the installation.
Pack of 100 for Electrical Panel Building and Maintenance
The Partex BF66/08/VR is supplied in a convenient pack of 100 terminals.
This quantity is particularly useful for electrical panel builders, maintenance engineers, equipment manufacturers and electrical contractors carrying out repeated termination work.
Keeping a consistent supply of matching connectors can help improve workshop efficiency and reduce interruptions during wiring and assembly.
The pack format also makes the product suitable for maintenance stock where compatible 6.3 mm female spade terminals are frequently required.
For larger wiring projects, using the same correctly specified terminal throughout the installation can help maintain consistent connection quality and simplify future servicing.
