Codos Y y T

A Y fitting joins branches at an angle, reducing turbulence and maintaining better airflow through the duct run. A T fitting connects a branch at 90 degrees and is better suited to tight spaces where an angled connection is not practical.

Most stationary machines such as table saws, jointers, and band saws use 4-inch ports. Portable tools, routers, and sanders typically use 2-1/2-inch ports. Check your machine's dust port diameter before ordering fittings.

Yes. A reducer Y fitting such as the 4" x 2-1/2" Y Fitting lets you branch a smaller-diameter line off a larger trunk without fabricating a custom adapter.

Quick-connect elbows use a push-fit or snap mechanism to join without fasteners. The 2-1/2" 90 Quick Connect Elbow is ideal when you frequently move portable tools and need to reconfigure hose runs quickly.

Blast gates are strongly recommended at each branch. Without them, suction is divided across all open ports simultaneously, reducing airflow at every machine. Closing unused blast gates directs full suction to the tool in use.

Most fittings in this collection are sized to accept standard spiral or rigid PVC duct as well as flexible dust hose of the same diameter. Verify the fitting style (slip, compression, or quick-connect) matches your hose or duct type.

Each fitting and length of duct adds resistance. As a general rule, minimize the total number of 90-degree turns and keep runs as short as possible. Using 45-degree elbows where space allows also helps preserve airflow velocity.

Dust collection fittings in this collection are typically made from ABS or PVC plastic, which is lightweight, durable, and develops less static charge than metal duct when grounded properly.
