Rubber Coated Neodymium Pot Magnet – 43mm Diameter with 20mm Nylon P Clamp

The Rubber Coated Neodymium Pot Magnet – 43mm Diameter with 20mm Nylon P Clamp is a versatile rare earth magnetic mounting assembly designed for securing and routing compatible cables, hoses, pipes, conduit and similar components against ferromagnetic steel surfaces. It combines a 43mm diameter rubber coated neodymium magnetic base with a 20mm nylon P clamp, providing removable mounting without requiring holes to be drilled or brackets welded to the supporting steel structure.

The magnetic base incorporates high-performance Neodymium Iron Boron (NdFeB) permanent magnetic material. Its protective rubber coating helps reduce direct metal-to-metal contact with the mounting surface while increasing friction to improve resistance to sliding.

The attached 20mm nylon P clamp provides a convenient method of supporting and organising compatible components. This combination makes the assembly suitable for industrial equipment, machinery, automotive applications, electrical installations, workshops and other environments where cable or hose routing may need to be repositioned.

20mm Nylon P Clamp

The integrated 20mm nylon P clamp provides a practical method of routing and supporting compatible round components.

Depending on the application, this may include:

• Electrical cables
• Wiring looms
• Flexible hoses
• Tubing
• Conduit
• Pneumatic lines
• Other compatible components

The nylon construction provides a lightweight, non-metallic support around the retained component.

The stated 20mm clamp size should not automatically be interpreted as confirmation that every component with a nominal 20mm diameter will fit identically. Actual component outside diameter, flexibility, clamp geometry and required compression should be checked before installation.

43mm Rubber Coated Magnetic Base

The 43mm diameter magnetic base provides removable attachment to suitable ferromagnetic steel surfaces.

This allows cables, hoses and other components to be routed along existing steel structures without permanently modifying the supporting surface.

Potential mounting locations include compatible:

• Machinery frames
• Steel cabinets
• Vehicle structures
• Equipment housings
• Steel panels
• Storage systems
• Fabricated structures
• Workshop equipment

The assembly can be removed and repositioned when equipment layouts or routing requirements change.

Protective Rubber Coating

The rubber coating creates a protective contact layer between the magnetic assembly and the steel mounting surface.

Compared with an exposed metal pot magnet, the rubber exterior can:

• Help reduce direct metal-to-metal contact
• Increase friction against the mounting surface
• Improve resistance to sliding
• Help protect painted or finished steel surfaces
• Provide additional protection around the magnetic assembly

Surface protection cannot be guaranteed. Dirt, metal particles or abrasive grit trapped beneath the magnetic base may still mark or scratch the mounting surface.

Neodymium Rare Earth Magnetic Performance

The magnetic base incorporates Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material known for providing strong magnetic attraction relative to its size.

No batteries, electrical wiring or external power source are required to maintain the magnetic attachment.

For maximum practical holding performance, position the magnetic base against clean, flat and sufficiently thick ferromagnetic steel with as much direct contact as possible.

Removable Cable and Hose Management

A major advantage of this magnetic P-clamp assembly is its ability to create a removable cable or hose mounting point without drilling or welding the supporting steel.

This can be particularly useful for:

• Temporary installations
• Prototype equipment
• Frequently reconfigured machinery
• Mobile equipment
• Maintenance applications
• Retrofit installations
• Situations where drilling is undesirable

If routing requirements change, the magnetic assembly can be removed and repositioned to another suitable steel location.

Direct Pull vs Shear Holding

Magnetic holding performance varies significantly according to the direction of the applied force.

The strongest condition is generally direct pull, where force acts perpendicular to the steel surface.

When the assembly is installed on a vertical surface, the weight of the clamp and retained component creates a shear or sliding load. Practical holding capacity under these conditions can be considerably lower than direct-pull performance.

The rubber coating helps increase friction and resistance to sliding, but vertical holding capacity should not be assumed to equal direct-pull capacity.

Vibration and Dynamic Loads

Where this magnetic P clamp is installed on machinery, vehicles or other equipment exposed to movement, consider the effect of:

• Vibration
• Shock loads
• Sudden movement
• Cable or hose tension
• Changes in load direction
• Leverage on the magnetic base

Dynamic forces can reduce the reliability of a magnetic mounting arrangement compared with a stationary installation.

Where detachment could create a safety hazard or equipment damage, consider an appropriate secondary retention method.

Getting the Best Magnetic Holding Performance

Actual magnetic performance depends on factors including:

• Steel thickness and composition
• Surface flatness
• Available contact area
• Paint or protective coatings
• Air gaps
• Rust or contamination
• Direction of applied force
• Weight of the retained component
• Cable or hose tension
• Vibration and movement

Keep both the rubber coated magnetic base and mounting surface clean and maximise flat contact wherever possible.

Please Note

No specific pull-force rating has been provided for this product, so maximum holding capacity should not be inferred from the 43mm diameter or neodymium construction.

Confirm the actual outside diameter and characteristics of the cable, hose, pipe or conduit to ensure it is compatible with the 20mm nylon P clamp before installation.

This assembly is designed for attachment to compatible ferromagnetic surfaces such as iron and steel. Aluminium, copper, brass, plastic, timber and many grades of stainless steel will not provide effective magnetic attachment.

For applications involving significant vibration, movement, overhead positioning or safety-critical components, assess whether secondary mechanical retention is required.

Keep strong magnets away from children, pacemakers, medical implants, magnetic storage media and sensitive electronic equipment.
