Rubber Coated Neodymium Pot Magnet – 88mm Diameter x 40mm | Rubber-Lined P Clamp

The Rubber Coated Neodymium Pot Magnet – 88mm Diameter x 40mm with Rubber-Lined P Clamp is a heavy-duty rare earth magnetic mounting assembly designed for securing pipes, cables, hoses, conduits and other compatible cylindrical components to ferromagnetic steel surfaces. Featuring a substantial 88mm diameter rubber-coated magnetic base combined with a 40mm rubber-lined P clamp, this assembly provides a practical removable mounting solution for industrial, automotive, engineering and equipment installations.

The magnetic base incorporates powerful Neodymium Iron Boron (NdFeB) permanent magnetic material. Its rubber-coated exterior helps protect the mating steel surface from direct metal-to-metal contact while also increasing friction to improve resistance to sliding. The attached 40mm P clamp provides a defined routing and retention point for compatible cylindrical components.

This combination of a powerful magnetic mounting base and rubber-lined clamp allows equipment to be installed on suitable steel without permanently drilling or welding into the supporting structure, making it particularly useful for temporary, adjustable and frequently repositioned installations.

40mm Rubber-Lined P Clamp

The integrated 40mm rubber-lined P clamp is designed to provide a secure retention point for appropriately sized cylindrical components.

P clamps are commonly used for routing and supporting:

• Pipes
• Hoses
• Electrical cables
• Wiring looms
• Conduit
• Tubing
• Hydraulic lines
• Pneumatic lines

The rubber lining provides a cushioned interface between the clamp and the retained component, helping reduce direct metal-to-metal contact.

The suitability of the clamp should always be confirmed against the actual outside diameter, material and operating requirements of the component being secured.

Powerful 88mm Neodymium Magnetic Base

With an 88mm diameter, the magnetic base provides a substantial contact area for attachment to suitable ferromagnetic steel.

The assembly incorporates Neodymium Iron Boron (NdFeB), a high-performance rare earth permanent magnetic material capable of producing strong magnetic attraction without an electrical power supply.

For optimum holding performance, the complete magnetic base should make close, flat contact with clean and sufficiently thick ferromagnetic steel.

Protective Rubber Coating

The rubber coating around the magnetic base provides important practical benefits for equipment mounting.

It creates a protective barrier between the magnetic assembly and the steel mounting surface, helping reduce direct metal-to-metal contact. The rubber can also increase friction at the contact point, providing improved resistance to sliding when the assembly is mounted vertically or subjected to sideways forces.

This makes rubber coated pot magnets particularly useful for mounting equipment to painted steel panels, machinery, vehicles and finished metal structures.

Surface protection cannot be guaranteed if dirt, grit or abrasive particles become trapped between the magnet and the mounting surface.

Magnetic Mounting Without Drilling or Welding

A major advantage of this magnetic P clamp assembly is the ability to route or secure components without permanently modifying the supporting steel.

The magnetic base can be positioned where required and repositioned when equipment layouts change.

This can be especially useful for:

• Temporary installations
• Prototype equipment
• Frequently reconfigured machinery
• Mobile equipment
• Maintenance applications
• Retrofitting cables and hoses
• Installations where drilling is undesirable

The permanent magnet requires no wiring, batteries or external power source.

Industrial, Automotive and Equipment Applications

The combination of a large 88mm magnetic mounting base and 40mm P clamp makes this assembly useful for applications requiring secure but repositionable routing of pipes, cables and hoses.

Potential users include:

• Industrial maintenance teams
• Equipment manufacturers
• Automotive technicians
• Fabricators
• Machinery builders
• Electrical installers
• Hydraulic and pneumatic technicians
• OEM equipment designers

The magnetic mounting method can simplify installations where access to the rear of a steel panel is limited or where drilling into existing equipment is undesirable.

Direct Pull vs Vertical and Shear Holding

Magnetic holding performance varies considerably according to the direction of the applied load.

A magnetic base typically achieves its greatest holding force when pulled directly away from the steel surface. When installed vertically, the weight of the clamp and retained component creates a shear or sliding load.

Practical vertical holding capacity can therefore be substantially lower than a direct-pull test value.

The rubber coating increases friction and can help resist sliding, but it should not be assumed that shear holding capacity is equivalent to direct-pull performance.

Getting the Best Magnetic Holding Performance

For optimum performance:

• Mount onto clean, flat ferromagnetic steel
• Use sufficiently thick steel where possible
• Maximise contact across the 88mm magnetic base
• Keep the mounting surface free from loose dirt and debris
• Avoid unnecessary air gaps
• Consider the weight of the retained pipe, cable or hose
• Account for vibration and movement
• Consider leverage created by the attached component
• Test the complete installation under actual operating conditions

Paint, protective coatings and the magnet's own rubber layer create separation between the magnetic material and target steel. Magnetic attraction decreases as this distance increases.

Please Note

No specific pull-force rating has been provided for this product, so a maximum holding capacity should not be inferred from the 88mm magnet diameter.

The 40mm P clamp size should be checked against the actual component being retained before installation.

Where the assembly will experience vibration, movement, dynamic loads or significant mechanical forces, assess whether additional restraint or a secondary retention system is required.

This product should not be used for lifting people, overhead suspension or safety-critical load holding unless the complete installation has been appropriately engineered, tested and rated.

Neodymium magnets are powerful but brittle. Avoid severe impacts or inappropriate machining. Keep strong magnets away from children, pacemakers, medical implants, magnetic storage media and sensitive electronic equipment.
