Picture this: you're elbow-deep in an engine repair, and a frost plug gives out, or you've got a plumbing hole that needs blocking fast. Instead of scrambling for tape or makeshift solutions that fail, reach for these neoprene rubber expansion plugs. This 14-piece set gives you six practical sizes—3/4", 7/8", 1", 1-1/8", 1-1/4", and 1-3/8"—that stretch to fit openings from 19mm to 38mm wide.
Neoprene's natural resilience means these plugs hold up against heat, cold, oils, and chemicals you encounter in automotive work or home repairs. They're not flimsy; they expand under pressure for a tight, leak-proof seal every time. Reuse them too—just clean and store for the next emergency.
In the garage, swap out a cracked freeze plug on your truck's engine without draining coolant. Around the house, plug an old faucet hole during renos or seal a temporary drain line. I've used mine to pressure-test radiator systems and block off AC lines—no more drips or air leaks frustrating your workflow. They compress easily for storage in your toolbox, always ready when Murphy strikes.
Whether you're a weekend wrench-turner or pro mechanic, these plugs save time and hassle. Fit most standard automotive and plumbing scenarios, and at this count, you'll have spares for the toughest jobs. Grab the set and plug into peace of mind today.
