Disposable Earmuff and Headset Covers

Earmuffs Not Included

Swap these covers out after every use to keep shared earmuffs, headsets, and headphones germ-free without sterilizing them. Made of a hypoallergenic mesh fabric, they’re unlikely to irritate sensitive skin and won’t affect sound quality. An elastic band makes them easy to stretch over ear cups.

Caps for Pipe Flanges

Push on these caps to cover the face and edge of pipe flanges or the ends of flared and beaded tubing. They prevent surface scratches and hole damage during shipping and storage as well as mask while painting and coating.

Vinyl Plastic—A good all-around choice, these durable caps won’t rip or shred, even with repeated use. They also hold up to oils, mild acids, and solvents. Caps are flexible and conform to parts for a tight fit.

No-Spill Caps

Even if beakers, bottles, and flasks are tipped upside down, liquids stay sealed inside. Tug on the tabs to stretch these caps over openings. Not only are they safer and more secure than foil or film covers, they can be used again and again. Autoclave to sterilize, or just toss in the dishwasher.

High-Temperature Silicone Rubber—These caps withstand temperatures up to 350° F as well as exposure to chemicals such as acetone and isopropyl alcohol.
