Note: These parts are for couplings manufactured after 1992.  If your coupling was manufactured pre: 1992 the seal kit TPT10571 should work if the shaft is in good condition.  Use AWS68 hydraulic oil.  Otherwise, you will need a new coupling T201670.

The Trojan duofit oil-dampened couplings are the only couplings that comply fully with the New Zealand standard for towball couplings NZS5232:1993 in all respects.

They are designed to suit 50mm and 1’’ 7/8 tow balls and The 2500kg rated couplings are suitable for trailers with a GVM of over 2500kg, are made from high-grade cast iron, and are coated significantly with corrosion protection for long-term maintenance-free use. A large range of spare parts is also available. These couplings are ideal for use on horse floats and caravans.
