Item #
82% of 100

Control dust collection right at the source with this unique blast gate. It attaches directly to 4" dust ports on your power tools and features a rubber fitting that not only guarantees a tight connection, but also is flexible enough to accommodate slight variations in the size and shape of the port. The other end is sized to accept standard 4" hose (sold separately).

I like them
I bought a couple of these and I really like them, they fit nicely on my bandsaw and table saw, quick and easy to install as long as you have some 4" hose clamps laying around

4" Blast Gates
These do the job when it comes to closing off one hose and opening another. No leakage.

Fits perfectly on standard 4" connector
Because there is a flexible end on the gate and a fitted hose clamp slot this gate goes on perfectly. I put a gate on each end of a standard 4" 'Y' so that I could use each end going into my cyclone (CNC or Vacuum wand) .Taking the hose off my CNC to do cleanup was a pain so this solution resolved the problem. When I want to use the CNC, just that gate is opened else the gates are switched for cleanup. This way there is only one gate opened at a time going into the cyclone. Perfect!

Swivelling blast gate works great
I didn't think the swivelling nature of the blast gate would make a difference, but in my confined space, it did.

Hoping this is a step up from my old way of managing hoses.
Kevin K on Jan 3, 2019
Getting new tools and the idea of the rubber boot built in is attractive.
Robert M. J on Nov 25, 2018
Reduce the amount of vacuum because without it may collapse the smaller hose and not stay connected to the portable tool. my collector has a Y so i can attach it to the unused part of the Y.
Kj on Sep 24, 2018
because i needed it
james h on Aug 19, 2018

I am using these to isolate the two main lines in my shop dust collection system, keeping the flow in the active line maximized.
David M on Mar 15, 2017
These gates slip over the tool port easily and make it so convenient to have each tool with its own air flow control
Philip D on Mar 4, 2017
ease of connecting blast gate without needing an extra piece of hose between it and the machine.
Gerald E on Feb 11, 2017

David J on Feb 10, 2017
Need to go from pipe fitting on Y adapter to pipe. Would be nice if the blast gate had both a male and female ends so could put it between things.

Will these fit the intake port on my Jet ? Item number is 58281.
Rick R on Jun 9, 2018
BEST ANSWER: Yes it will fit your Jet on one of the two 4" ports, but not the 6" obviously. Just make sure you're ordering Rockler #37825 which is the Tool Blast Gate as it has the rubberized union on one side to attach it to your tool or collector. The less expensive blast gates (#32020) would go between two 4" hoses but you need the rubberized union, or you'll have to buy a 4" union separately, so this is both the best deal and easiest way for you to attach a blast gate to your Jet JCDC-1.5
Does the gate close completely? I have purchased blast gates and some of them have a small opening at the end of the gate that still lets air get through, I want a gate that completely closes off!
Ricky T on Mar 6, 2017
Yes it does close completely at first. But after a while the slot that the gate closes into fills up with debris and causes the gate not to close completely. Hope this helps.

What are the OD sizes on the gate?
Warren W on Sep 2, 2017
BEST ANSWER: The hose side is ID 3 5/8 in, OD 3 7/8 in. The rubber boot side is ID 4 in, OD 4 3/8 in.
What size screw clamp do i need for the rubber boot? Does a 4” work?
Can this #37825 be used with a Dust Right quick change handle to put a shut off at the inlet (hose end) of the handle to close when not in use? Thank-you in advance!
