Partex YF66/FI/VR yellow fully insulated female push-on terminal for compatible 6.3 x 0.8 mm male blade connections, designed for crimp termination onto suitable electrical conductors and supplied in a pack of 100.
£10.24
The Partex YF66/FI/VR is a professional fully insulated female push-on terminal designed for connecting suitable electrical conductors to compatible 6.3 mm × 0.8 mm male blade terminals. Featuring yellow insulation and a fully insulated connector configuration, this electrical termination accessory provides a practical solution for control panel wiring, machinery connections, electrical equipment assembly and industrial maintenance.
Part of the Partex insulated push-on terminal range, the YF66/FI/VR combines a crimp-style conductor termination with a detachable push-on connection. Its fully insulated construction extends the insulating covering over the female receptacle, providing greater connector coverage than a conventional partially insulated push-on terminal. This makes it particularly useful where additional insulation around the connection is desirable, subject to the electrical and environmental requirements of the installation.
The 6.3 mm × 0.8 mm mating dimensions allow the terminal to connect to appropriately sized male blade tabs, while the yellow insulation provides a recognisable finish for conductor termination and identification. Supplied in a convenient pack of 100, the Partex YF66/FI/VR is suitable for electrical contractors, panel builders, OEM equipment manufacturers and maintenance engineers requiring consistent insulated push-on connections.
The Partex YF66/FI/VR fully insulated push-on terminal provides a practical solution for connecting electrical conductors to compatible male blade terminals. Its 6.3 mm × 0.8 mm mating dimensions are suited to electrical equipment using corresponding blade connections, provided that the connector's conductor capacity, electrical ratings and installation requirements are satisfied.
The fully insulated design distinguishes the YF66/FI/VR from conventional partially insulated female push-on terminals. By extending the insulating covering around the receptacle body, the connector provides additional insulation coverage at the connection point. This can be useful in control cabinets, electrical assemblies and equipment wiring where closely positioned connections require careful insulation management.
Although the terminal is fully insulated, the completed connection must still comply with the equipment's electrical safety requirements. Protection against accidental contact depends on the complete mating arrangement, installation condition and enclosure design. The connector should not be assumed to be touch-safe, waterproof or suitable for live disconnection without explicit manufacturer confirmation.
Correct crimping is essential for dependable electrical performance. The conductor should be stripped to the length recommended for the terminal, taking care not to damage the copper strands. The prepared conductor is inserted fully into the crimp barrel before being compressed using a suitable insulated terminal crimping tool. The resulting connection should be inspected for correct compression, conductor retention and insulation condition.
Once crimped, the female connector can be pushed onto a compatible 6.3 mm × 0.8 mm male blade. The connection should engage securely without excessive force, looseness or damage to the terminal. Installers should verify the suitability of the mating tab, conductor cross-section and connector electrical ratings before energising the equipment.
The yellow insulation provides a convenient visual identification feature, while the 100-piece pack makes the YF66/FI/VR practical for production wiring, routine maintenance and workshop stock management. The result is a versatile electrical connection accessory for professional installers and equipment manufacturers.

The Partex YF66/FI/VR is a fully insulated female push-on terminal designed to connect a suitably sized electrical conductor to a compatible 6.3 mm × 0.8 mm male blade terminal.
The YF66/FI/VR is designed for a nominal male blade size of 6.3 mm wide × 0.8 mm thick. The mating tab must have compatible dimensions and connector geometry.
Fully insulated means the connector has insulating coverage extending around the female push-on receptacle rather than only the conductor crimp area. This provides additional connector coverage compared with a partially insulated push-on terminal, although complete electrical protection depends on the finished installation.
The YF66/FI/VR features yellow insulation, providing a recognisable finish for electrical terminal identification and wiring assembly.
Each pack contains 100 Partex YF66/FI/VR fully insulated push-on terminals, suitable for electrical installation, equipment assembly and industrial maintenance applications.
The YF66/FI/VR is a female push-on connector designed to mate with a compatible male blade tab measuring 6.3 mm × 0.8 mm.
Both products are yellow Partex push-on terminals for compatible 6.3 mm × 0.8 mm male blades. The YF66/FI/VR has a fully insulated connector configuration, while the YF66/08/VR is a conventional insulated push-on terminal without the same fully insulated designation.
The conductor must fall within the manufacturer's approved crimping range for the YF66/FI/VR. The yellow insulation should not be used as the sole basis for selecting conductor size; confirm the terminal's specified capacity before installation.
Use a crimping tool suitable for the terminal's insulated crimp barrel and approved conductor size. Confirm that the crimping profile and tool capacity are compatible with the YF66/FI/VR before use.
No such protection should be assumed. Fully insulated describes the connector's insulation coverage and does not automatically establish a waterproof rating or suitability for live disconnection. Always isolate the electrical supply before disconnecting the terminal and follow the equipment manufacturer's safety instructions.
Partex electrical connection products support panel builders, machinery manufacturers, installation contractors and industrial maintenance engineers. The YF66/FI/VR fully insulated push-on terminal combines a 6.3 mm × 0.8 mm mating connection, yellow insulation and convenient 100-piece pack to support neat, consistent and professionally prepared electrical wiring connections.
