Why Choose the Partex SHSB-3 Solder Heatshrink Butt Connectors?
The Partex SHSB-3 is a solder heatshrink butt connector designed for joining electrical conductors with cross-sectional areas from 1.5–2.5 mm². Combining heat-activated solder joining with heatshrink insulation, these connectors provide a practical solution for creating inline wire connections in electrical equipment, wiring harnesses, industrial machinery and maintenance applications.
Unlike conventional crimp butt connectors, the Partex SHSB-3 incorporates a solder joining section within a heatshrink sleeve. When correctly heated, the solder melts to form an electrical connection between the prepared conductors while the surrounding sleeve contracts around the joint. This allows conductor joining and insulation to be completed in a single installation process without requiring a separate mechanical crimping operation.
Supplied in a convenient pack of 25 connectors, the SHSB-3 is suitable for electrical contractors, control panel builders, equipment manufacturers and industrial maintenance engineers. Its 1.5–2.5 mm² conductor range makes it particularly useful for compatible medium-section wiring connections, cable repairs and electrical assembly work where a soldered inline splice is appropriate.

Solder Heatshrink Butt Connectors for Industrial Electrical Wiring
Solder heatshrink butt connectors are designed to create inline connections between compatible electrical conductors. Their integrated solder joining section allows the prepared wire ends to be connected through controlled heating, while the surrounding heatshrink sleeve contracts to provide insulation around the completed joint. This type of connector is useful for wiring harness assembly, electrical equipment maintenance and conductor repairs where soldered splices are permitted.
The Partex SHSB-3 is designed for conductors from 1.5–2.5 mm². During installation, the conductor ends should be correctly stripped, inserted into opposite ends of the connector and positioned within the solder joining area. Controlled heat is then applied until the solder flows and the sleeve contracts around the connection. The joint should be allowed to cool without movement and inspected before use. Installers should verify that the connection method is suitable for the electrical load, operating environment and applicable installation requirements.
Typical Applications
- Electrical wiring harness assembly and repair.
- Industrial machinery wiring maintenance.
- Electrical equipment conductor repairs.
- Control panel auxiliary wiring where soldered splices are permitted.
- Joining compatible 1.5–2.5 mm² electrical conductors.
- OEM electrical equipment manufacturing.
- Inline cable repairs and wiring extensions.
- Industrial electrical maintenance and servicing.

Frequently Asked Questions
What is the Partex SHSB-3 used for?
The Partex SHSB-3 is a solder heatshrink butt connector used to join compatible electrical conductors end to end. It combines a heat-activated solder connection with a heatshrink sleeve to create an insulated inline wire splice.
What wire sizes are compatible with the Partex SHSB-3?
The SHSB-3 is designed for electrical conductors with cross-sectional areas from 1.5 mm² to 2.5 mm². Both conductors should be suitable for the connector and the intended electrical application.
How do you install a Partex SHSB-3 solder heatshrink connector?
Strip the conductor ends to the appropriate length, insert them into opposite ends of the connector and position them within the solder joining area. Apply controlled heat using suitable equipment until the solder flows and the heatshrink sleeve contracts. Allow the connection to cool without movement and inspect the completed joint before use.
Does the Partex SHSB-3 require a crimping tool?
No. The SHSB-3 uses a heat-activated solder connection rather than a conventional mechanical crimp. A suitable controlled heat source is required to melt the solder and shrink the insulating sleeve.
How many Partex SHSB-3 connectors are supplied in a pack?
The Partex SHSB-3 is supplied in a pack of 25 solder heatshrink butt connectors, suitable for electrical wiring repairs, cable assembly and maintenance applications.
