Is there any type of PVC pipe that would fit directly over a 4” dust port on a table saw? Would I need an adapter of some sort? I’m assuming the dust ports on machines are standard.

It might be best to connect a section of flexible 4” DC hose to the saw and then connect to the hose to the PVC. This would allow some movement in lieu of having a rigid connection. 4” DC hose seems to connect well to the machines in my shop which I then run to a blast gate at each fitting on the PVC collection pipe.

BalsaWood,

An option for making the 4” PVC slip over the machine 4” port is to cut 2 or 3 pieces of ¾” thick MDF glued and screw together to the outside diameter of the machine’s dust port. Using a heat gun, heat the end of the PVC 4” pipe until it softens. Then press the softened PVC pipe over the MDF die and let the PVC cool. A stick inserted into the pipe to make contact with the die and then striking the stick with a hammer will dislodge the die. I found that chamfering the edge of the MDF die makes slipping the softened PVC over the die easier. Some paste wax applied to the die’s sides helps dislodge the PVC pipe once it has cooled.

You can expand or shrink pvc with a heat gun or torch. I heat it, it gets soft then fit it over something then I use a stainless steel band clamp to tighten it down. It hardens at that size after it cools.

^^^^^^This.

If it’s close with a heat gun you can make any of the assorted plastic parts fit onto another part. Hold it in place till it cools, when you pull it off it will retain the shape it cooled to. Presto Chango, parts fit. Just heat until it gets a “little” soft (PLIABLE), going overboard will get you drippy plastic. Do a test before going at something that would cost some bucks to replace. Once you have it down, like riding a bike.

Heating the PCV tube with a propane torch or heat gun. I’ve used the torch method to soften the plastic to both expand and shrink the PCV tubes to fit over tightly. Have not required to use clamps, but I do use duct tape to help keep from slipping off once and a while.

It probably depends on the table saw. I was able to slip a PVC street L over the port on my SS, but that’s the first time I’ve had anything fit a tool with no mods.

One thing for certain is that there is no standard for dust ports or dust collection fittings.
