Heating Sleeve (tuleja grzewcza) 40 mm NEO tools 21-015

Heating Sleeve (tuleja grzewcza) 40 mm by NEO tools is a compact, single-size heating sleeve designed to deliver concentrated local heat for repair and maintenance tasks. With a 40 mm inner diameter, this sleeve is intended for controlled thermal application on fittings, small shafts, connectors and other metal components where localized heating is required. The product is suitable for workshop and field use and supports operations such as loosening seized fittings, shrink-fitting bearings or performing thermal treatment on metal parts.

Advantages

The 40 mm heating sleeve provides focused heat transfer to a confined area, reducing the need to heat the entire assembly. Its compact size and single-diameter design make it easy to position and use in tight spaces. Constructed to withstand repeated heating cycles, the sleeve offers predictable thermal behaviour that aids precision tasks. The design simplifies application of heat for mechanical and repair work while minimizing heat exposure to adjacent components.

Suitable for

• Loosening seized nuts, bolts and fittings by localized heating
• Shrink-fitting small bearings, sleeves and press-fit components
• Thermal treatment or stress relief of small metal parts
• Workshop maintenance and on-site repair tasks requiring focused heat

Key specifications

• Inner diameter: 40 mm
• Single-size sleeve for concentrated heating
• Suitable for metal components and fittings
• Compact form factor for use in confined spaces
• Designed for repeated use in repair and maintenance operations

How to use

Position the heating sleeve around the component to be heated so that the sleeve makes even contact with the target area. Apply a suitable heat source according to the heat source manufacturer's instructions and heat progressively until the required temperature or looseness is achieved. Monitor the component and surrounding areas during heating to avoid overheating or damage. After finishing, allow the part and sleeve to cool before handling, dismounting or performing subsequent assembly operations.

Usage recommendations

Use appropriate personal protective equipment and follow safe heating practices: maintain a controlled heat input, avoid direct contact with hot surfaces, and keep flammable materials away from the working area. Select a heat source compatible with the sleeve and the material being treated, and follow the heat source manufacturer's guidance for safe operation.
