Why Choose the Partex ECHS232BROWN 2:1 Heat Shrink Tubing?
The Partex ECHS232BROWN is a brown 2:1 heat shrink tubing product designed for electrical wire insulation, cable identification and protection of small electrical connections. Featuring a nominal supplied diameter of 3.2 mm and a nominal fully recovered diameter of 1.6 mm, this tubing provides a practical solution for electrical installations, control panel wiring, electronics assembly and cable harness manufacturing.
With its 2:1 shrink ratio, the ECHS232BROWN is designed to reduce to approximately half its original diameter when correctly heated and allowed to recover fully. This enables the tubing to conform closely around appropriately sized wires and components, creating a neat insulating sleeve. Its distinctive brown colour also supports visual conductor identification and colour-coded electrical wiring arrangements.
Supplied in a generous 150 m pack, the Partex ECHS232BROWN is particularly suitable for electrical contractors, panel builders, electronics technicians and cable assembly manufacturers requiring consistent quantities of heat shrink sleeving for repeated installation and production work.

Effective Wire Insulation and Brown Cable Identification
The Partex ECHS232BROWN provides a practical method of insulating and identifying electrical wires using heat-activated tubing. Its nominal supplied diameter of 3.2 mm allows it to be positioned over appropriately sized conductors or components, while its 2:1 recovery ratio enables the tubing to shrink towards a nominal recovered diameter of 1.6 mm when sufficient heat is applied.
For effective installation, the tubing should be selected according to the dimensions of the item being covered, cut to the required length and heated evenly using suitable equipment. The brown colour can support an established electrical wiring identification scheme, including conductor identification where permitted by applicable standards. The 150 m supply quantity makes it convenient for workshops and production environments. Applications requiring specific dielectric ratings, operating temperatures, flame classifications or environmental certifications should be checked against the relevant Partex product specifications before installation.
Typical Applications
- Electrical wire insulation and protection.
- Brown colour identification of electrical conductors.
- Electrical control panel wiring.
- Electronics assembly and repair.
- Cable harness manufacturing.
- Low-voltage control and signal wiring.
- Protection of compatible wire connections and splices.
- Instrument and sensor wiring identification.
- Industrial automation equipment wiring.
- Electrical maintenance and refurbishment.
- Production-line wire sleeving operations.
- Applications requiring brown 3.2/1.6 mm heat shrink tubing.

Frequently Asked Questions
What is the Partex ECHS232BROWN used for?
The Partex ECHS232BROWN is brown heat shrink tubing used for insulating, identifying and protecting suitably sized electrical wires and small components.
What does the 2:1 shrink ratio mean?
A 2:1 shrink ratio means the tubing is designed to recover to approximately half its original diameter when correctly heated and allowed to shrink fully.
What are the supplied and recovered diameters of ECHS232BROWN?
The tubing has a nominal supplied diameter of 3.2 mm and a nominal fully recovered diameter of 1.6 mm.
What colour is the Partex ECHS232BROWN?
The tubing is supplied in brown, making it suitable for visual identification of wires and components within an established colour-coding scheme.
How much Partex ECHS232BROWN tubing is supplied?
The specified pack quantity is 150 m of brown Partex ECHS232BROWN heat shrink tubing.
Can the ECHS232BROWN tubing be cut to length?
Yes. The tubing can be cut into suitable lengths before being positioned over the wire or component and heated to achieve the required fit.
How is the Partex ECHS232BROWN installed?
Select tubing that fits over the item before shrinking, cut it to the required length and apply heat evenly using suitable equipment. Follow the manufacturer's recommended heating and installation conditions.
Can ECHS232BROWN be used for electrical phase identification?
Brown tubing can be used within an appropriate wiring identification system, including applications where brown identifies a line conductor. Identification must comply with the applicable wiring standards and the installation's established colour-coding requirements.
Is ECHS232BROWN suitable for large power cables?
The nominal supplied diameter is 3.2 mm, so the tubing is intended for appropriately sized wires and components. Larger cables generally require heat shrink tubing with a larger supplied diameter.
Is the Partex ECHS232BROWN adhesive-lined?
The specified product information identifies the tubing's size, colour, shrink ratio and quantity but does not confirm an adhesive lining. Applications requiring adhesive-lined or moisture-sealing tubing should use a product with those properties explicitly specified.
Does ECHS232BROWN provide waterproof sealing?
Waterproof sealing is not established by the supplied specifications. Where moisture sealing is required, select tubing with a verified sealing construction and the appropriate manufacturer rating.
What is the difference between ECHS232BROWN and ECHS216BROWN?
Both products are brown 2:1 heat shrink tubing supplied in 150 m quantities. The ECHS232BROWN has nominal supplied and recovered diameters of 3.2/1.6 mm, whereas the ECHS216BROWN has smaller nominal diameters of 1.6/0.8 mm.
