Fenaetimo Trailer Axle Grease Caps Kit — 6 Galvanized Dust Caps + 12 Rubber Plugs, 2.72 in Corrosion‑Resistant

Fenaetimo's 2.72-inch trailer axle grease cap kit includes six galvanized metal dust caps and twelve rubber lube plugs designed to seal and protect 7,000–8,000 lb trailer wheel hubs.

This complete hub protection set is built for heavy-duty trailers, campers and RVs that use standard 2.72" (approx.) axle grease caps. The galvanized iron caps resist corrosion and deformation while the resilient rubber plugs keep grease in and contaminants out. The kit provides spare parts for quick replacement and routine maintenance so you can keep bearings lubricated and hubs cleaner longer.

How do these grease caps keep my trailer hub protected?

The solid iron caps form a physical barrier against water, dirt and road debris, preventing contaminants from reaching the bearing area. The included rubber plugs sit inside the cap opening to retain grease under pressure and simplify re-lubrication without removing the entire cap.

• Galvanized iron construction resists rust and bending.
• Rubber plugs offer elasticity and chemical resistance to oils.
• Complete set supplies spares for multiple hubs or replacements.
• Seal design reduces contamination during travel and storage.

Will these caps fit my axle and how do I confirm compatibility?

These caps measure approximately 2.72 inches in diameter and about 1.53 inches high, matching many standard hub sizes used on 7,000–8,000 lb trailers. To ensure a correct fit, measure your existing cap diameter and hub depth or compare to manufacturer specifications before ordering.

• Cap outer diameter: ~2.72 inches.
• Cap height: ~1.53 inches.
• Best for standard 7,000–8,000 lb trailer hub assemblies (confirm dimensions first).
• Handy when replacing worn or corroded original caps.

How easy is installation and routine maintenance with this kit?

Installation is straightforward: press the metal cap into the hub recess and seat the rubber plug for grease retention. The rubber plugs are detachable for quick access during greasing and are flexible enough for repeated removal and reinsertion.

• Press-fit installation—no special tools required for most hubs.
• Detachable rubber plugs simplify grease access and inspection.
• Includes extra plugs for replacement during service intervals.
• Lightweight design makes swapping caps quick at roadside or shop.

What are the materials and durability features of this hub cap set?

The caps are forged from iron with a galvanized finish to reduce oxidation and withstand harsh road environments. The lube plugs use premium rubber formulated for toughness, elasticity and resistance to water, oil and common chemicals encountered in routine trailer maintenance.

• Galvanized surface resists corrosion and keeps structural integrity.
• Iron body resists deformation from impact or vibration.
• Rubber plugs resist oils and chemicals for long service life.
• Packaged quantity minimizes downtime with spare components.

Who is this for: The Fenaetimo 2.72" Trailer Axle Grease Cap kit is intended for trailer owners, RV and camper operators, service shops and fleet managers who maintain 7,000–8,000 lb axles and need durable replacement dust caps with spare rubber plugs. It suits anyone who wants a corrosion-resistant, easy-to-install solution to keep bearings lubricated and hubs protected during towing, storage and routine maintenance.
