Frequently Asked Questions

Q: What Pintle Hooks are compatible with this ring coupling?

A: This 75mm ring coupling is compatible with several heavy-duty hooks, including the Premium Combination Pintle Hook (3.5t), Combination Pintle Hook (6t), 6.0t Combination Pintle Hook (33.6kN), 10t Truck Pintle Hook (CTA-045738), and the 70mm Tow Ball x 10t Truck Pintle Hook (CTA-061572).

Q: How do I calculate the correct D-Value for my truck and trailer combination?

A: The D-value measures the horizontal forces between the towing vehicle and the trailer. For example, a 10t truck towing a 10t trailer requires a 49kN D-Value rating. If you run an 8,500kg GVM vehicle with a 4,500kg ATM trailer, your minimum required D-value is 29 kN.

Q: When should my pintle ring coupling be replaced due to wear?

A: The accepted mechanical safety standard for wear replacement is when the profile has worn down by 5% or more of the ring’s original manufactured diameter.

Q: How do I reduce wear and noise when using combination pintle hooks?

A: Couplemate™ highly recommends installing a dedicated tow ball protector. This simple addition greatly extends the overall lifespan of the coupling and significantly lowers operational towing noise.

Does this ring coupling have a warranty?

  • With a complete 12-month warranty, you can feel confident towing around Australia. Read our warranty policy online here.

Will this ring coupling work for my application?

  • Your towing vehicle must always be heavier than your towed vehicle.
  • Even if your trailer is rated to 10 tonnes, this pintle ring will not work if your truck is 10 tonnes or under.
  • Your D-value is more important than the 10-tonne rating. 10-tonne determines the absolute upper limit: your d-value determines the actual rating.
This ring coupling suits the following pintle hooks:
  • Premium Combination Pintle Hook
  • 3.5t Combination Pintle Hook – 6t Ring Coupling
  • 6.0t Combination Pintle Hook (33.6kN)
  • 10t Truck Pintle Hook CTA-045738
  • 70mm Tow Ball x 10t Truck Pintle Hook CTA-061572
  • 58kN x 10t Truck Pintle Hook CTA-016120
  • 49kN x 10t Truck Pintle Hook CTA-045738

What’s included in the box?

  • 1 x COUPLING-RING-255
  • Not Included: 4 x M16 high-tensile bolts for the trailer drawbar, base plate (required to use this ring coupling)

How do I install this ring coupling?

  • Fit the coupling onto your drawbar’s base plate with four M16 high-tensile bolts.
  • This ring coupling requires a base plate to be welded onto your drawbar, if you do not already have one.

How durable is this coupling?

  • This ring coupling is made of ductile iron 500/12. Its yield strength is 500. Its elongation is 12%.
  • This yield strength results in less wear: your coupling won’t wear faster than your pintle hook.
  • Elongation refers to the amount of flex something has before it breaks. This ring coupling has a small amount of flex.
Coating

Black powder coating. A coating that is more resistant to damage as a result of:

  • impact
  • moisture
  • chemicals
  • ultraviolet light
  • Other extreme weather conditions

How do I maintain this ring coupling?

  • Ensure you regularly torque the bolts on the Coupling-Ring-255 and inspect the coupling ring for signs of wear.
