Parma's Hot Spot Markers

Hot Spot Markers provide a clear visual warning of wheel end component failure, changing to permanent orange when the hub temperature exceeds 180°C. Designed for trucks, trailers, and buses, they help detect overheating brakes and wheel bearings early, preventing costly damage.

Made from durable materials with 3M self-adhesive backing, they attach directly to the metallic wheel hub housing for accurate heat detection. Proper installation requires alcohol wipes or sandpaper for a secure bond.
