Dexter Grommet Dust CapChrome Plated Accu-lube Grease Cap suits Boat trailers or utility trailers.

Easy to check contaminated grease. Just remove the rubber ring and check for black or brown bearing grease. If black or brown grease is found, remove the entire hub and re-grease.

Black grease is caused by bearing wear. The casting on the bearing wears over time.

Poorly adjusted bearings cause heat and greatly accelerate bearing wear.

Question: Should I fill my dust cap full of grease.

Answer: No, the purpose of the grease cap is to catch excess grease from the bearing cavity. Your grease cap should be inserted dry.

Grease is generally in oversupply during the greasing process and will exit the bearing cavity at high speeds and during the initial heating and cooling process. Note: Grease never re-enters the bearing cavity once caught in the grease cap.

Further, remove all grease and clean when removing grease caps.

What is the purpose of the dust cap?

  • To catch grease?
  • Or to prevent the ingress of dust?
  • To assist bearing inspection. If you see black grease in the dust cap, then your bearing requires a clean and readjustment or replacement.

The resultant bearing wear causes carbon to discolour the grease.
