VALCRUM OIL CAP 6K-8K ALKO

The Valcrum Oil Cap for AL-KO 6K–8K axles is a heavy-duty threaded hub/oil cap used on trailer axles to contain and protect the wheel-hub lubricant. It can be used for either an oil-bath or grease-lubricated hub.

Main functions

• Seals the wheel hub: Keeps oil or grease inside the hub and helps prevent contamination from entering.
• Allows oil-level inspection: The clear viewing window lets you visually check the lubricant level without removing the cap.
• Provides easy filling/draining: A side access port allows lubricant to be added or drained without removing the entire cap.
• Reduces heat: The aluminum-alloy construction dissipates heat better than conventional plastic caps, helping with hub temperature management.
• Captures metal particles: The magnetic vent plug attracts metallic debris from the lubricant, which can help identify bearing or hub problems early.
• Protects against corrosion: The black e-coat finish provides additional corrosion resistance.
• Provides a tight seal: The O-ring and gasket help prevent lubricant leaks and keep contaminants out.
