Marine
Engineered for the sea.
Saltwater destroys steel. UV destroys plastic.
Biofouling, wave loading and 25-year service cycles destroy almost everything else. Rubber, formulated correctly and certified to standard, is what gets specified. For more than thirty years RDL has developed and produced rubber components for the marine industry across New Zealand. From elastic mooring systems in the Marlborough Sounds to fenders and seals on vessels around the coast, every part begins with the same brief: survive longer than the steel it is bolted to.
Elastic mooring systems
Custom elastomeric lines that absorb wave loading without the snatch of chain and rope. Field-proven across recreational and commercial moorings.
Marine fenders
Extruded fenders, specified across a wide range of sizes.
Hatch seals and gaskets
UV and ozone-stable extruded profiles, heat-age tested for marine service.
Anti-vibration mounts
Engine bay and hull-mounted isolators damping cyclic vibration before it cracks the structure.
Floating-array location cord
Extruded cord that locates and anchors floating solar units to their bases.
Bonded marine components
Rubber-to-metal assemblies built to the customer's drawing and inspected to certificate.
Compounds for this environment.
- EPDMEthylene Propylene
Ozone, UV and weather resistance. The default for above-waterline applications.
- CRNeoprene
Balanced oil, weather and flame resistance. Often specified for fenders and hatch seals.
- NRNatural Rubber
Tear strength and resilience. Used where shock absorption matters more than chemical resistance.
- FKMViton
Aggressive chemicals and high heat. Specified for engine-bay components in fuel-adjacent environments.
Marine Flex elastic mooring system
Engineered elastomeric mooring line developed to absorb wave cycles without the snatch loading of conventional chain and rope. Field-deployed across recreational and commercial moorings.
Send us the part that has to outlast the steel it's bolted to.
The vessel, the load, the cycle, the environment. We specify the compound, prototype the part and prove it on the bench before it ships.
