Conductor size
Give the wire cross-section in mm² or AWG and describe the conductor construction. Use the selected terminal’s wire-range table rather than insulation colour alone.

Choose the Right Terminal Connection
| Connection | Product families | Series | Selection focus |
|---|---|---|---|
| Stud connections | Ring, fork and locking fork terminals | RV · SV · LSV | Confirm the stud diameter, contact width and space around the screw connection. |
| Equipment contacts | Pin, chip and hook terminals | PTV · DBV · HV | Match the contact shape, insertion depth and dimensions to the equipment drawing. |
| Detachable connections | Male, female and fully insulated female terminals | MDD · FDD · FDFD | Specify both mating halves, tab dimensions and the required insulation coverage. |
| Wire-to-wire joints | Bullet connectors and butt connectors | MPD · FRD · BV | Match bullet mating dimensions or confirm the conductor combination for each splice. |
| Branch connections | Piggy back terminals | PBDD | Check the female receptacle and additional male tab against both mating components. |
Match the Terminal to Your Wire and Equipment
Start with the connection drawing, then review conductor size, contact dimensions and crimp requirements as a complete assembly.
Connection dimensions
Provide the stud size, mating tab width and thickness, pin dimensions or bullet contact diameter, as relevant to the series.
Crimp construction
Confirm the terminal barrel, approved crimp tool and die, stripping length and installation instructions for the selected model.
Service conditions
Tell us the operating temperature, electrical requirements and installation environment. Request model-specific information; vinyl insulation does not establish a waterproof connection.
Tell Us Which Terminals You Need
Send a model list, wire sizes, mating dimensions and quantities. TONFUL can review product selection, sample requests and packaging with your enquiry.

Vinyl-Insulated Terminal Buying Questions
Can I select vinyl-insulated terminals by colour alone?
No. Colour can help identify a product family, but the exact conductor range and connection dimensions must come from the selected model’s product table or approved drawing.
Are the different terminal series interchangeable?
Not automatically. A ring, fork, pin, blade, bullet or spade contact is designed for a particular connection. Check its geometry, mating dimensions, wire range and installation requirements before substitution.
What is the difference between female and fully insulated female terminals?
The listed FDD family has an exposed female contact with an insulated wire barrel. The FDFD family adds insulation around the female contact. Confirm the coverage and mating dimensions for the exact model.
Are vinyl-insulated terminals waterproof?
Do not assume a sealing rating from the insulation material. For moisture-exposed wiring, ask for a product and installation method with verified environmental requirements.
What should I send for a quotation?
Send the exact terminal part numbers, wire sizes, mating dimensions, quantities, sample requirements, packaging preferences and delivery destination. A drawing or sample reference helps us review the request.
Can TONFUL review OEM labels and packaging?
Yes. Share the artwork, identification needs and quantities per pack. The available options, minimum quantities and delivery terms are confirmed in your quotation.
