About Duct Connections
More
Chemical-Resistant Duct and Fittings
Made of PVC plastic to withstand acids, alkalies, salts, and other corrosive vapors and fumes. Use PVC pipe cement (not included) to secure components. Fittings have female ends with a slightly larger diameter to press-fit over duct.

Rain Hats
These sturdy hats are made of PVC-coated polyester to resist tears and mildew. A full brim shields rain from all sides. They're washable.
When measuring head circumference, measure just above your ear, where the hat will rest. If you are between sizes, order one size up.
Disposable Hats and Hairnets
Keep your hair out of the way to prevent stray hairs from contaminating food.
Bouffant-style hats and hairnets cover your entire head. For short- to medium-length hair, use those with a 20" to 21" stretched diameter; for longer or thicker hair, choose a 24" stretched diameter.
Tyvek polyethylene fabric holds up to occasional contact with nonhazardous liquids, such as water and paint spray. It is made of heat- and pressure-bonded fibers that form a barrier that's soft yet strong.
Kleenguard polypropylene fabric is made of five layers of nonwoven fabric, so it is harder to tear than Tyvek polyethylene. It holds up to occasional contact with nonhazardous liquids, such as water and paint spray. The material is antistatic, so it protects sensitive equipment from electrostatic discharge.
Clean Room Hats and Hairnets
Also known as bouffants, these hats and hairnets keep hair contained to reduce contamination. Designed to meet clean room standards, they act as a barrier between the worker and the room to prevent pollutants, such as dust particles and microbes, from contaminating a space. They are rated Class 100 for use in clean rooms containing fewer than 100 particles larger than 0.5 microns in each cubic foot of air space. Use these hats and hairnets for short- to medium-length hair.

Stretchable Elastic Caps
Similar to a shower cap, these caps have an elastic band that allows them to stretch and cover a variety of shapes in a range of sizes. They are often used in masking applications to protect against contaminants.
