OAUTOO 110‑Piece Auto Body Hole Plugs Kit — Black Flush‑Mount Plastic Plugs, 12 Sizes, Weather‑Resistant

OAUTOO 110-piece flush-mount auto body hole plugs kit supplies a complete assortment of black plastic plugs to seal, protect, and restore vehicle body holes.

This kit groups 12 commonly used plug diameters into an organized selection of 110 pieces made from durable PE and TPU blends. Designed for exterior and interior trim, drain holes, door cavities, floor pans and other service openings, the plugs are shaped to sit nearly flush with the panel surface so they remain discreet while blocking moisture, debris and pests.

Which vehicle openings can these plugs cover?

These plugs work for a wide variety of body openings across many makes and models. They’re appropriate for drain ports, access holes for wiring or clips, door and bumper cavities, and undercarriage or floor pan holes where a low-profile seal is desired.

• Floor pan and underbody drain holes
• Front and rear door cavity covers and plug caps
• Bumper or fascia service holes and trim access points
• Interior panels, wiring pass-throughs and grommet replacements

How do I pick the right size from the 12-size assortment?

Measure the hole’s inner diameter for the most secure fit — choose a plug with a slightly larger flange and correct stem diameter so the plug compresses and locks in place. The kit lists twelve distinct sizes to match common vehicle hole dimensions, making it easy to trial-fit a nearby size if exact measurement isn’t available.

• Small holes: 8 mm and 9.5 mm options for wiring or small drain holes
• Medium holes: 11–18.5 mm range for door and panel access points
• Large holes: 22–32 mm options for bigger drain or service holes
• Keep a caliper or ruler handy and compare plug stem vs. hole diameter

Are these plugs durable enough for exterior use?

Yes — the plugs are made from a blend of polyethylene (PE) and thermoplastic polyurethane (TPU), which gives them flexibility plus resistance to weathering. That composition helps them maintain shape, tolerate vibration and resist cracking from temperature changes, while staying soft enough to form a tight interference fit.

• TPU adds flexibility and wear resistance
• PE contributes chemical and moisture resistance
• Low-profile flange reduces snagging and visibility
• Resists road grime, water intrusion and basic chemical exposure

How are these plugs installed and removed?

Installation is typically push-in only: align the plug with the hole and press until the flange sits flush with the panel. Removal can be performed with a trim removal tool, small flat screwdriver or pick to gently pry the plug out without damaging surrounding paint or panel edges.

• Push to seat until flange is flush
• Use trim tool or thin pick for removal
• Test-fit before final installation for best grip
• Replace worn plugs from the assortment as needed

Who this kit is for: the OAUTOO 110-piece assortment is suited to DIY enthusiasts, independent mechanics, body shops and fleet technicians who need a ready inventory of low-profile hole plugs for repairs and restorations. If you service multiple vehicle models, perform trim work, or patch drain and access holes frequently, this kit reduces the need to order individual sizes and speeds up repairs with a range of reliable, weather-resistant plugs.
