A Strong Link in the DC Chain 
This is a good connector for a DC system. Not a complicated piece, but a very good one. The ends were all 4" , the hose fit snuggly and the wire clamps held.When making a branch in the DC system, to go to several different pieces of equipment, the "Y" connection is better to use than the "T". The Y will allow for a better air flow. Combine the Y with a/several blast gates, then it's almost like having a single hose go to each piece of equipment.
Does a Great Job
When installing a dust collection system, eliminating resistance to airflow is what it is all about. The ideal is as large a pipe as possible, flowing in a straight line, without any ridges in the surface. Of course in the real world at least some of these things wind up being less than ideal. What this Jet 4" Y-connector does, is give you a large pipe, that makes a gradual Y as opposed to a straight 90 degree angle T, and the sides of the connector are smooth. So when you need to divide your air source into two lines, this elbow does the nicest job.
The advantage of incorporating a Y connector into your system, is that you can take a single air source, connect this Y connector to it, a pair of gates, and no longer have to switch your hoses between two different pieces of equipment. All you do is open the gate to one, and close it to the other. All in all highly recommended.
Great DC fitting!
Like all of my Jet dust collector fittings, I have been very pleased with the performance of this "Y" fitting, and it was much MUCH cheaper at my local Menards. I used these Y's in my main duct to create branches for my stationary tools on the long wall of my shop. The 4" size was perfectly consistent and always fit the ducting and flex hose without any trouble. The "Y" design greatly reduces any loss of air flow as compared to elbow fittings and the plastic is very strong and rigid.
Highly recommended as an essential accessory for any dust collection system.
Y Dust Hose Connector
This product is as described! Connected two tubes and made into one tube!! Used as a two tube converter to a one tube converter.
Easy to Use
Works fine to hook up my dust collection hoses for multiple tools. You should use a blast gate for each run to close it off when not in use.
