10. Fulton


Fulton 4 inch to 2 1/2 inch off-set Y Junction Fitting for 4 inch Hose to 2 1/2 inch Hose

Fulton #ad - Depending on your woodworking shop dust collection system, you generally will need to use different diameter hoses from time to time. The 4” to 2½” y will generally not fit into or around aluminum, pvc, plastic or rubber lines with the same diameters. Typically, the most commonly used diameter hoses are 4” and 2½”.

The 2½” port is angled on the side of the 4” to 2½” Y for better airflow. The 4” to 2½” y features recessed ports on all three openings. This way you can close the airflow from one diameter hose line to the other at your convenience. The 2-1/2” port inner diameter is approximately 2-5/16” and the outer diameter is approximately 2-15/32”. The inside of the 4” to 2½” y is smooth to help prevent the dust and debris that passes through the Y from clogging and building up. To re-direct airflow using the 4” to 2½” y you’ll need a blast gate NOT included for the 4” port, the 2½” or both ports.

The fulton 4” to 2½” y fitting is ideal for not only reducing your hose line from 4” to 2½”, it is also ideal for re-directing your airflow to effectively gain maximum suction into your dust collector. Each recess has more than enough length to easily accommodate PVC or standard style dust collection hose. The inside diameter of the 4” ports is approximately 3-45/64” and the outer diameter is approximately 3-15/16”. Please measure your dust collection hose before placing your order.
