Rubber D Fenders

Harbours, ports, boats and vessels endure on-going strain from knocks and bumps, which cause damage and erosion. This requires continuous upkeep to maintain the structural integrity of vessels and structures. Aquaseal’s rubber D fenders and cylindrical marine fenders form a protective barrier for structures and vessels to minimise the damage caused by impact.

A D shape boat rubber fender works by absorbing the kinetic energy of a boat or vessel berthing against a jetty, quay wall or other vessel, preventing damage.

Fenders can also be used at loading bays for lorries, trucks and any other unique applications where a protective barrier is required.

We use a specially compounded 70-shore Hardness EPDM rubber for our rubber d fenders. This makes them resistant to degradation, UV radiation, seawater and other environmental factors. This ensures that our marine fenders are a sturdy and long lasting product, built to stand the test of time.

Marine fenders can be installed either into a channel or bolted onto the required surface. Installation can be horizontally, vertically or diagonally. This is a practical and versatile solution for many industries and environments.

Our marine fenders can be pre-drilled, pre-curved, chamfered and cut to specific lengths. This will assist installation and meet requirements of application. Our rubber D fenders have a flat rear surface, so they easily install on to flat surfaces.

Aquaseal produces each boat rubber fender through a die, using the extrusion method. In addition to our range of standard sizes we can help design bespoke fender profiles for your own special requirements.

Our rubber D fenders and cylindrical fenders come in a wide range of sizes:

  • D fenders – from 20mm to 300mm in various D formats
  • Cylindrical fenders – variety of sizes up to a maximum outside diameter of 500mm and a maximum length of 5m long

Which Rubber D Fenders do you need?

PVC

PVC D fenders are a popular alternative to other rubber D fenders due to their non-marking surface and cost-effectiveness.

Natural Rubber

Natural rubber D fenders have a high resistance to tear and abrasion and high tensile strength.

Neoprene

Neoprene has high tensile strength, making it a great option for D fenders that experience a lot of movement. It also has high resistance against water so is often used as a marine rubber.

EPDM

EPDM is an ideal solution for marine D fenders due to its excellent resistance to weathering, ozone, and water.

Styrene Butadiene Rubber

Styrene Butadiene Rubber (SBR) also has great scratch resistance which is ideal for D fenders that are exposed to many bumps and knocks.
