POWERTEC70125 4-Inch Pipe Hose Adapter - ABS Plastic Quick Coupler for Workshop Dust Collection Fittings

I bought a couple  POWERTEC 70108 4-Inch Blast Gates  for my dust collector and found that the outer diameter was still way too small for the the inner diameter of 4" sewer pipe. This coupler provided the bridge to connect the blast gates to my 4" pipe. I ran a bead of silicone around the smaller side of the coupler to keep it secure and leak free.

This does not slip directly onto green 4" DWV SDR35 / ASTM D 1784/ ASTM D 2729 pipe.It however does fit really nicely into the couplings used for those pipes and it allows for the connection of a 4" dust hose which doesn't fit directly onto a 4" DWV pipe.

Durable and fit into the PVC perfect, however, getting the 4" flex hose on was very difficult. Got it eventually but took away 1 star in my review because of the poor fit. Once installed it worked as expected.

Works as expected

Good product despite negative reviews. Item description is not clear that it is designed for schedule 20 pipe.

I used this to make a dust collector quick connect. I hose clamped my four inch dust collection hose to one side and the other side goes on the 4" OD outlet of various shop tools (table saw, planer, etc). I lightly sanded the inside of the 4" ID side to make it a slightly looser fit on the dust collection ports. It still friction fits, but it is easier to get on and off.

This worked great as a quick disconnect for the dust hose on my Jet 16-32 drum sander.

PVC sewer line comes in two thicknesses. The common stuff is .090" thick and normally white. There is also a thicker type, often green in color, that has a .127" wall thickness. If your PVC (NOT ABS) pipe is the thinner version the smaller end of the adapter will fit into sewer pipe as described.I was not as fortunate with the other end fitting my hose. I only have one unknown brand of hose but it fits the factory dust port on my table saw as well as the 4" end of a Powertec 70136 4"x2-1/2" Reducer so I have to assume my hose has a fairly standard ID. The reducer OD is 3-61/64" and is a close slip fit to the inside of the big end of the 70125 adapter so I do not see how the big end is supposed to fit a 4" hose. The big end of the 70125 adapter is 4-7/32" so it is far too large to fit a 4" hose.Fortunately, the bigger end is close to the size of the ID of 4" PVC couplings and ells. I made it fit tightly by applying a single layer of blue painter's tape to the adapter and attached the hose to the smaller end with a hose clamp. Every joint in my dust collection system is fitted with blue painter's tape so it can be altered as needed.I would rate the item "not as described" but saw still able to make it useful.

Fits and works great.

Pleased

did the job

Nothing fit together, I ordered several fittings and y's etc. I order an adapter and you would think it would fit onto the Y, or the Gate, but NO everything are the same size, so you need a coupler, but they don't sell a coupler, so now I either need to use a 4" piece of flex hose, (which makes the joint weaker) or I will need to design and print my own with my 3d printer.
