Tecnoseal 01037 and 01038 are zinc sacrificial propeller nut anodes designed for Varifold VF160 and VF240 4-blade folding propellers. The 01037 replaces original Varifold part VF4AN and fits VF160 propellers with diameters from 26 to 32 inches, featuring a 67 mm outside diameter, 70 mm height, 9 mm axial opening and M16 thread. The larger 01038 replaces original part VF4AN(230)KIT and is specified for VF240 4-blade folding propellers over 32 inches, measuring 93 mm in outside diameter and 100 mm in height, with a 10 mm axial opening and M30×3.5 thread. Both feature a cylindrical body with a rounded, domed end and a central fastening arrangement. Manufactured from zinc, they weigh 1.20 kg and 3.76 kg respectively and provide sacrificial galvanic corrosion protection for compatible Varifold propeller assemblies.

Tecnoseal VF4AN / VF4AN(230)KIT Varifold VF160 / VF240 Zinc Propeller Nut Anodes

The Tecnoseal 01037 and 01038 are zinc sacrificial propeller nut anodes designed for Varifold VF160 and VF240 4-blade folding propellers. These replacement components correspond to original Varifold part numbers VF4AN and VF4AN(230)KIT and are manufactured for different propeller sizes and mounting configurations.

Both anodes feature a cylindrical body with a rounded, dome-shaped outer end and a central fastening arrangement. The internal mounting geometry includes a threaded connection, allowing the anode to be installed on the corresponding Varifold propeller assembly.

The Tecnoseal 01037 is intended for Varifold VF160 4-blade folding propellers with diameters from 26 to 32 inches. It measures 67 mm in outside diameter and 70 mm in height, with an M16 thread. The larger Tecnoseal 01038 is intended for Varifold VF240 4-blade folding propellers over 32 inches, measuring 93 mm in outside diameter and 100 mm in height, with an M30×3.5 thread.

Manufactured from zinc, these propeller nut anodes are designed to provide sacrificial corrosion protection for electrically connected underwater metallic components of compatible Varifold folding propeller systems.

Varifold Folding Propeller Compatibility

The Tecnoseal anodes are specified for two different Varifold folding propeller configurations:

Varifold VF160: 4-blade folding propellers with diameters from 26 to 32 inches. Replacement anode: Tecnoseal 01037, corresponding to original Varifold VF4AN.
Varifold VF240: 4-blade folding propellers with diameters over 32 inches. Replacement anode: Tecnoseal 01038, corresponding to original Varifold VF4AN(230)KIT.

The two versions have different dimensions and thread specifications and should not be considered interchangeable. Check the original part number, propeller model and fastening thread before ordering.

Design and Mounting Configuration

Both Tecnoseal anodes feature a cylindrical, nut-shaped body with a rounded upper end. The central mounting arrangement incorporates an internal threaded section and a smaller axial opening, as illustrated in the manufacturer's technical drawing.

The 01037 has an overall height of 70 mm and an outside diameter of 67 mm. Its central axial opening (Ø1) measures 9 mm, while the specified mounting thread is M16.

The larger 01038 measures 100 mm in overall height and 93 mm in outside diameter. It incorporates a 10 mm axial opening (Ø1) and an M30×3.5 mounting thread.

These dimensions are important for identifying the correct replacement and matching the anode to the intended Varifold propeller configuration.

Galvanic Corrosion Protection

The Tecnoseal 01037 and 01038 are manufactured from zinc and function as sacrificial corrosion protection components. When electrically connected to the underwater metallic parts requiring protection, the zinc corrodes preferentially, helping reduce galvanic corrosion of the propeller assembly.

Zinc sacrificial anodes are commonly used in saltwater environments. Confirm the suitability of the anode material according to the vessel's operating conditions and the Varifold manufacturer's recommendations.

Inspection and Replacement

Inspect the propeller nut anode during routine folding propeller maintenance and replace it when the zinc material is significantly depleted, damaged or no longer securely mounted.

Before installation, verify the original Varifold part number, propeller model and thread specification. Inspect the mounting surfaces and follow the propeller manufacturer's installation and fastening instructions.
