Genuine Part
Genuine: Original manufacturer part. This product is the original part designed and produced by the vehicle manufacturer.
Domed Nut - union nut securing a hydraulic pipe to an actuator in the ACE (Active Cornering Enhancement) anti-roll bar system.

It clamps the ACE high-pressure pipe union onto the suspension actuator port, retaining the connection that feeds hydraulic pressure to the actuator; a Dowty sealing washer (companion part RYF100420) seats under the union to seal the joint.

The ACE hydraulic circuit is highly sensitive to dirt ingress, so the connection must be kept scrupulously clean whenever it is disturbed.

Frequently asked questions

What is the ANR6653 Domed Nut used for?
The ANR6653 Domed Nut is the union nut that secures a high-pressure hydraulic pipe onto the actuator port in the ACE (Active Cornering Enhancement) anti-roll bar system. It clamps the pipe union down to retain the connection that feeds hydraulic pressure to the actuator. Genuine Land Rover part.
Does the ANR6653 need a sealing washer?
Yes, a Dowty sealing washer (companion part RYF100420) typically seats under the pipe union to seal the high-pressure joint. The domed nut clamps the union down onto that washer, so it's worth fitting a fresh washer whenever the connection is disturbed.
How many ANR6653 nuts are needed?
Typically one ANR6653 nut is used per ACE hydraulic pipe union. Quantity depends on how many connections you're disturbing, so check each actuator port you plan to open rather than assuming a single nut covers the whole job.
What should I watch for when fitting it?
Cleanliness is critical. The ACE hydraulic circuit is very sensitive to dirt ingress, so keep the union and actuator port scrupulously clean whenever the connection is opened. Any debris drawn into the high-pressure circuit can damage the ACE system.
