Hyfico Aluminum RV Bumper End Caps — 2-Pack for 4" Square Camper Bumpers, Ventilated, Bolt-On Replacement

Hyfico's aluminum RV bumper end caps are a ventilated, bolt-on two-piece set designed to protect and conceal 4-inch square camper bumpers and stored sewer hoses.

These replacement end caps deliver a corrosion-resistant aluminum shell, left-and-right hinge design for a finished appearance, and small vents that promote airflow while keeping pests out. The kit includes everything needed for a straightforward retrofit: two end caps, rubber sealing pads, stainless fasteners, and aluminum buckles so you can replace weathered plastic caps or upgrade exposed bumper storage quickly.

How do these end caps protect my travel trailer's sewer hose and bumper?

The rigid aluminum housing shields stored hoses and the bumper interior from sun, rain, and road debris. Its durable construction reduces UV damage and cracking that can occur with older plastic caps, extending the life of the components inside.

• High-grade aluminum resists rust and fading in outdoor exposure
• Closed, contoured shape keeps out dirt and splash from the road
• Included rubber pads form a dampening seal at mounting points

Will these fit my camper's bumper and how easy is installation?

They are made to fit standard 4-inch square bumper tubes commonly found on RVs, travel trailers, and pop-up campers. No drilling or frame modification is required—these mount with the supplied stainless bolts and buckles for a secure fit.

• Universal fit for 4" square bumper tubes
• Bolt-on installation with supplied hardware—no cutting needed
• Left and right pieces ensure correct orientation and symmetry

Do the vent holes compromise protection or allow pests inside?

The vents are micro-sized to allow airflow and reduce trapped moisture while minimizing entry points for insects or rodents. The pattern balances ventilation to keep stored hoses dry without exposing them to nesting risks.

• Micro vents promote airflow, preventing mildew and damp odors
• Small aperture size discourages small animals from entering
• Vent placement reduces water pooling and condensation inside

What design details improve appearance and function compared to older caps?

Each cap is split into left and right sections that close on a hinge, producing a cleaner, factory-style look. Smooth operation and tight latching help keep the cover aligned and reduce rattling while driving.

• Individual left/right caps give a symmetrical, finished look
• Smooth hinge action for easy opening and secure closure
• Matte or brushed finish resists visible wear and hides road grime

Who this is for: RV owners, weekend campers, and travel-trailer DIYers who want a long-lasting upgrade for bumper-mounted sewer hose storage. If you need a durable replacement for cracked plastic caps, prefer aluminum for corrosion resistance, or want vents that reduce moisture without inviting pests, this Hyfico two-pack provides an easy, maintenance-reducing solution.
