Tecnoseal 119 / 120 Flexofold 2-Blade Composite Propeller Side Anodes (Pair of 2)

Tecnoseal 119 / 120 Flexofold 2-Blade Composite Propeller Side Anodes (Pair of 2)

The Tecnoseal 01043 and 01043AL are sacrificial propeller side anodes designed for Flex-O-Fold 2-blade composite folding propellers. Supplied in pairs, these replacement anodes help protect electrically connected underwater metallic components of compatible propeller assemblies against galvanic corrosion.

The two versions correspond to original Flexofold references #119 (Zinc) and #120 (Aluminium). Both share the same compact, contoured rectangular mounting design with a recessed central fastening hole. Each anode measures 37 mm (1.46 in) in length, 23 mm (0.91 in) in width and 16 mm (0.63 in) in height, with a 10 mm recess diameter and a 6 mm mounting hole.

The zinc version has a catalogue weight of 0.13 kg (0.29 lbs), while the aluminium version weighs 0.04 kg (0.09 lbs). Both are supplied in pairs, allowing replacement of the corresponding propeller side anodes.

Technical Specifications

Available Variants

• Tecnoseal 01043 – Zinc: Replacement for Flexofold OEM #119. Supplied as a pair of two zinc side anodes. Dimensions: 37 × 23 × 16 mm. Catalogue weight: 0.13 kg.
• Tecnoseal 01043AL – Aluminium: Replacement for Flexofold OEM #120. Supplied as a pair of two aluminium side anodes. Dimensions: 37 × 23 × 16 mm. Catalogue weight: 0.04 kg.

Compatibility with Flexofold Propellers

These Tecnoseal anodes are designed for Flex-O-Fold 2-blade composite propellers. The manufacturer's catalogue identifies both versions as replacement propeller side anodes supplied in pairs.

Before ordering, verify the original Flexofold part number and compare the shape, dimensions and central fastening arrangement with the existing anodes. Compatibility with other Flexofold propeller configurations is not specified for these particular models.

Design and Mounting Configuration

Each anode features an elongated, contoured body with rounded edges and a central mounting opening. The recessed hole arrangement allows the fastening component to sit within the anode body.

The technical drawing specifies a length of 37 mm, width of 23 mm and overall height of 16 mm. The central mounting area includes a 10 mm recess diameter (Ø) and a 6 mm fastening hole (Ø1).

Both zinc and aluminium versions share identical dimensions and mounting geometry, making the sacrificial material the primary difference between the two available variants.

Corrosion Protection and Material Selection

The Tecnoseal 01043 and 01043AL are manufactured as sacrificial corrosion protection components. The anode material corrodes preferentially, helping protect electrically connected underwater metallic components of compatible Flexofold propeller assemblies against galvanic corrosion.

• Zinc: Commonly used for sacrificial protection in saltwater environments.
• Aluminium: Suitable for many saltwater and brackish-water applications, subject to the propeller manufacturer's recommendations.

Select the anode material according to the operating water conditions and the original propeller specifications. Avoid mixing incompatible sacrificial materials within the same protection arrangement without confirming the manufacturer's recommendations.

Inspection and Replacement

Inspect the propeller side anodes during routine maintenance and replace them when significantly consumed. Check the mounting points and ensure suitable electrical contact with the metallic components requiring protection.
