When heavy loads demand unwavering security and long-term resilience, the Geomet Coupling – 6000kg Capacity – 70mm (T614065GM) stands ready as a purpose-built solution for demanding towing applications. Designed to fit 70mm tow balls, this heavy-duty coupling is the trusted choice for large boat trailers, commercial equipment transport, and industrial fleets where every connection matters.

The standout feature is Geomet’s premium coating. The Geomet zinc-aluminium finish is non-electrolytically applied, delivering superior corrosion protection compared with traditional galvanised or zinc-plated finishes. That means your trailer hitch resists rust, moisture, and the harsh realities of marine, coastal, and high-wear environments—extending service life and reducing downtime.

With a robust 6000kg load rating, this coupling provides confidence when towing heavy loads over long distances. Its heavy-duty construction is engineered to withstand commercial and industrial use, while the secure connection between trailer and tow vehicle minimizes movement for improved stability on the road.

• 6000kg rated towing capacity — ready for heavy boat trailers, plant trailers, and industrial transport
• 70mm tow ball compatibility — matches standard heavy-duty towing setups
• Geomet zinc-aluminium coating — exceptional rust and corrosion resistance in marine and harsh environments
• Heavy-duty construction — built for reliability in commercial, industrial, and high-stress use
• Marine & coastal ready — designed to endure salt spray and humidity without coating failure
• Low maintenance — extended service life with fewer touch-ups and replacements

Who is this Geomet Coupling ideal for? Fleet operators and tradespeople who demand dependable performance in tough surroundings—think large boat trailers, construction and mining equipment transport, plant trailers, and heavy equipment fleets that operate near water or in challenging climates.

Why choose Geomet over standard couplings? The combination of a true 6000kg capacity and the advanced Geomet coating means longer intervals between maintenance and a reduced risk of corrosion-related failures. In environments where moisture, salt air, and abrasive grime are constant companions, this coupling delivers lasting stability and peace of mind on every job.

Practical notes to maximise lifespan and performance:

• Keep mating surfaces clean and free of mud, salt, and debris to preserve the coating and fit
• Inspect the coating and welds regularly for signs of wear, cracking, or chipping
• Avoid aggressive chemicals near the coating; rinse with fresh water after exposure to salt or chlorinated environments
• Store in a dry, shaded area when not in use to minimize surface wear on the coupling
