You’ve got options right here. Walmart’s bottle caps selection includes styles for homebrewing, water jugs, and crafting. You’ll see:

• Crown beer caps, including oxygen-absorbing liners for bottling.
• Swing-top flip caps for reusable glass bottles.
• Reusable silicone covers for beer, wine, soda, and soft drinks.
• Replacement caps for 3–5 gallon water jugs (commonly 55mm).
• Plastic screw caps and flattened/colored caps for DIY crafts.

Use filters to narrow by type, size, or color, and check the product details for dimensions and compatibility. Availability can vary by location and online inventory. You can shop online, choose pickup, or delivery where offered.

Great question—names help you shop the right fit.

• Crown caps (often 26mm): Pry-off caps used for beer bottling; some include oxygen-absorbing liners.
• Screw caps: Twist-on plastic or metal caps found on many beverage bottles.
• Swing-top (flip) caps: Reusable hinged stoppers for glass bottles.
• Growler caps (commonly around 38mm): Replacement caps for half-gallon or gallon jugs.
• Gallon jug caps (often 55mm): For 3–5 gallon water dispensers.
• Silicone bottle covers: Flexible, reusable toppers for beer, wine, or soda bottles.
• Heat-shrink wine capsules: Decorative sleeves used to finish wine bottles.

Always check the diameter and finish to match your bottle.

A quick size check can save time and returns.

1. Measure the opening: Use a ruler or caliper to note inner diameter.
2. Match common standards: 26mm for crown beer caps, 38mm for many growlers, and 55mm for 3–5 gallon water jugs. Some plastic craft caps list sizes like 29.5–30mm.
3. Check the finish: Pry-off vs. twist-off, threads, or swing-top compatibility.
4. Review product details: Look for dimensions, neck finish notes, and intended use (brewing, water, crafts).
5. Buy a small pack first: If you’re unsure, test before buying in bulk.

Sizes can vary by bottle brand and style, so confirming measurements helps avoid mismatch.

Several options can be reused, depending on condition and setup.

• Swing-top flip caps: Designed for reuse; inspect gaskets before each use.
• Silicone bottle covers: Flexible toppers that can be used multiple times; useful for short-term storage.
• Growler caps: Typically reusable; replace if threads or seals wear out.
• Crown caps: Generally pressed on once and not reused; oxygen-absorbing versions are single-use.

Rinse or sanitize caps according to your process, and check for cracks, warping, or compromised seals. Reuse can work well when the cap and bottle stay compatible, but results can vary based on your bottling method and storage conditions.

Keeping silicone caps in good shape helps maintain a reliable seal.

1. Wash before first use: Use warm, soapy water and rinse thoroughly.
2. Routine cleaning: Hand-wash after each use; check product details for dishwasher guidance, as care instructions can differ.
3. Dry completely: Air-dry to prevent moisture buildup inside the cap.
4. Inspect regularly: Look for tears, thinning, or misshapen areas; replace if damaged.
5. Store smart: Keep caps in a clean, dry container away from sharp objects and prolonged heat or direct sun.

These habits can help extend the life of your caps, but durability varies with frequency of use and handling.
