Setup, Compatibility & Care

Compatibility: Ensure these grease nipples are compatible with your trailer's hub size (4" PCD) and metric fittings before installation.
Tools: You may need a grease gun, wrench, or other tools to remove the old nipples and install the new ones.
Installation: Remove the old grease nipples. Clean the area around the hub. Screw the new grease nipples into the hub until they are snug. Do not overtighten.
Greasing: Use a grease gun to inject grease into the nipples. Follow your trailer's maintenance schedule for greasing frequency. The surface-sprung ball check will prevent grease from flowing out when not in use.
Care: Regularly inspect the grease nipples for damage or corrosion. Replace them if they show signs of wear. Clean any dirt or debris from the area before greasing.
