Conductor cross-section
Use the cross-section specified for the ferrule. For a twin ferrule, state the size of each conductor; do not substitute a single-wire model based only on the sum.
Wire Ferrules
Manufacturer
Insulated, non-insulated and twin wire ferrules for conductor-end preparation. Compare E, EN and TE series, then specify the conductor cross-section, sleeve length and terminal requirements.
One conductor or two?
Start with the ferrule type.
| Series | Construction | Selection focus |
|---|---|---|
| E — insulated wire ferrules | Tubular metal sleeve with an insulating collar | Single-conductor size, sleeve length and collar clearance |
| EN — non-insulated wire ferrules | Metal sleeve without an insulating collar | Conductor size, sleeve length and equipment insulation requirements |
| TE — twin wire ferrules | Common sleeve and collar for two conductors | Size of each conductor and terminal acceptance of the finished crimp |
A ferrule must fit
both wire and terminal.
Sleeve & stripping length
Compare the metal sleeve length with the terminal’s insertion depth and stripping instructions. Overall ferrule length and metal sleeve length are not the same measurement.
Finished crimp profile
Confirm the tool, die and finished crimp dimensions suit the ferrule and terminal entry. Square and hexagonal profiles are not automatically interchangeable in every terminal.
Specify the wire.
We’ll review the ferrule.
Send E, EN or TE models, conductor sizes, sleeve lengths and quantities. Add your colour code and packing plan.

Agree the exact model and inspection requirements before procurement. Match supporting documents to the product you are buying.
Dimensions & materials
Confirm the model drawing, conductor range, sleeve or barrel dimensions, metal finish and insulation specification.
Tooling & connection
Request the applicable preparation and crimping instructions. Agree tooling and any connection-test requirements for the intended assembly.

Wire ferrule
buying questions.
What are wire ferrules used for?
Wire ferrules gather the strands at a conductor end for insertion into a compatible terminal. Whether a ferrule is needed, permitted or unsuitable depends on the terminal manufacturer’s instructions.
Are bootlace ferrules and cord-end terminals the same product type?
These names commonly refer to tubular wire-end ferrules. Confirm the exact series, conductor range, sleeve length and collar arrangement when comparing products.
What is the difference between E, EN and TE?
E is the insulated single-wire series, EN is the non-insulated series, and TE is the twin-wire series. Open the corresponding product page for model dimensions.
Can a twin ferrule be used in any terminal?
No. Confirm the terminal accepts that conductor arrangement and the resulting crimp dimensions. Two conductors in one ferrule do not make every terminal suitable for a two-wire connection.
Can I choose the size by collar colour?
Do not use colour alone. Specify conductor cross-section and model, then confirm the colour coding required for your order. Coding can vary between ranges and markets.
Do all models have the same approvals?
Do not assume a range-wide approval. Provide the required standard and request documentation covering the exact model, conductor and applicable tooling combination.
Can you quote assortments and private-label packs?
Send quantities by model and colour, pack sizes, labels and artwork. Assortment feasibility, samples, MOQ and lead time are confirmed in the quotation.
