防尘帽
Dust Cap
The first line of defence for ball joints and ports
Once grit and water enter a ball joint, rod end or port, wear and corrosion accelerate. A dust cap grips the part elastically, flexing with the joint while sealing over the long term. We offer ball-joint covers, port caps and bolt protection caps.
Key features
Tight grip
Interference-fit neck stays in place.
Flexes with the joint
Domed shape follows articulation without tearing.
Keeps grease in
Retains lubricant to extend joint life.
Material choice
NR for resilience, EPDM for weather, NBR for oil.
