Standard Duct and Fittings
No need for clamps or connectors—duct and fittings press-fit together. Male ends are crimped or tapered, making them slightly smaller than a female end for simple assembly.
Galvanized steel has good corrosion resistance. Aluminum is more lightweight than steel and stainless steel and has good corrosion resistance. 304 stainless steel is more corrosion resistant than steel and aluminum.

Ball joints create adjustable-angle connections. They are often used to connect duct to duct hose. Hold duct hose in place with a hose clamp (not included).
Gas Chimney Vents and Fittings
For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.
To join pipes and connectors, insert a male end into a female end and secure with the included locking band.

Adjustable-angle elbow connectors can be used at an angle or straight.
Adapters for Liquid-Tight Flexible Plastic Conduit
Use these adapters to attach liquid-tight flexible plastic conduit to a knockout in an outlet box or enclosure. They provide a connection that seals out liquid and resists oil, corrosion, and UV light. They are UL listed when used with abrasion-resistant liquid-tight flexible plastic conduit (Type B).
Adapters with a push-in end are removable and reusable.
Adjustable-angle elbow adapters can be positioned at any angle from 0° to 90°.

Connectors for Rigid PVC Conduit
Join pieces of PVC Schedule 40 or Schedule 80 conduit. These connectors are lightweight, corrosion resistant, and UV light resistant for outdoor use. They can be buried or encased in concrete. PVC cement is required (not included) to secure the connection.
Adjustable-angle elbow connectors also attach conduit to a knockout when you take off the removable ends to access the threaded connections.
