Dsnaduo 6 Sizes Neoprene Expansion Plug Set – 14 Pieces, Fits 3/4" to 1-1/2" Holes

Overview: Flexible sealing with a 14-piece neoprene plug kit

The Dsnaduo 14-piece neoprene rubber expansion plug set blends versatility and practicality for automotive work, workshop tasks, and quick sealing needs. With six sizes included, you’re equipped to tackle holes across a broad range with confidence. The collection emphasizes flexibility and immediate usability, so you can respond to a variety of sealing tasks without hunting for individual plugs.

Expanded hole coverage for real-world use

Designed to fit a spectrum of hole diameters, the plugs span from 3/4" up to 1-1/2" (19mm to 38mm). The kit’s six-size layout is organized to provide the closest fit for each hole category, reducing the guesswork when you’re in the middle of a project.

• 3 pieces fit holes 3/4" to 7/8" (19mm–22mm)
• 3 pieces fit holes 7/8" to 1" (22mm–25mm)
• 2 pieces fit holes 1" to 1-1/8" (25mm–28mm)
• 2 pieces fit holes 1-1/8" to 1-1/4" (28mm–31mm)
• 2 pieces fit holes 1-1/4" to 1-3/8" (31mm–34mm)
• 2 pieces fit holes 1-3/8" to 1-1/2" (34mm–38mm)

What you get and practical applications

The set includes 14 plugs across six sizes, designed to serve as replacement rubber expansion plugs, frost plugs, or exhaust pressure test plugs in appropriate tasks. The neoprene material offers elasticity and a forgiving seal, accommodating slight variance in hole size while keeping the opening protected from dust or moisture on a temporary basis.

Use cases: scenarios where these plugs shine

• Automotive work: temporarily seal openings during maintenance or inspections to minimize debris entry.
• Testing and prototyping: create a quick seal for leak checks or air/pressure experiments without fabricating a custom plug.
• Workshop and DIY projects: close off non-critical openings for short-term projects, filtering out dust and contaminants.

Choosing the right size and care tips

Measure the hole diameter and pick the closest size within the provided ranges for a snug, non-forcing fit. Store plugs in a cool, dry place away from direct sunlight to maintain elasticity, and inspect before reuse to ensure an effective seal.
