SteveKoz Posted March 21, 2019 Report Share Posted March 21, 2019 Can someone share what part they used to connect 4" PVC to 4" flex hose? Right now I have a 6" to 4" SDR reducer with bells on both ends. Would like to have a connector that I can screw on a 4" flex hose. Can either fit into the bell of the 4" or I can put a short piece of 4" pvc into the bell and then insert the adapter. I purchased one on Amazon and it doesn't fit. Instead of trial and error I figured I'd ask the group. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
Chestnut Posted March 21, 2019 Report Share Posted March 21, 2019 Blast gate. Should have a gate at every tool anyway. 1 Quote Link to comment Share on other sites More sharing options...

wtnhighlander Posted March 21, 2019 Report Share Posted March 21, 2019 The 4" hose I use fits over a 4" pvc 'street L', an elbow that is female on one side, male on the other. Quote Link to comment Share on other sites More sharing options...
gee-dub Posted March 21, 2019 Report Share Posted March 21, 2019 I do as Chestnut does. Sub-optimal, abrupt size change but, unfortunately it works 'well enough' so I have never gone back to change it . Metal gates, same thing. Quote Link to comment Share on other sites More sharing options...
Minnesota Steve Posted March 21, 2019 Report Share Posted March 21, 2019 I haven't tried this... but Rockler has long had adapters for schedule 20 pipe, and last year or so they introduced adapters for schedule 40. https://www.rockler.com/rockler-schedule-40-pvc-to-4-hose-adapter Quote Link to comment Share on other sites More sharing options...

Sch 40 is NOT the same as SDR35 they both say 4" but they are both not 4". The OP asked about SDR pipe which i hope he understands the difference. On SDR35 pipe the blast gate or other dust fittings fit nicely inside and offer an inexpensive options beings that a blast gate is < adapter. Not sure why a more complex assembly with more parts is cheaper but alas it is. SDR35 will be sloppy inside a SCH40 fitting leaving problems.

Gary Beasley Posted March 21, 2019 Report Share Posted March 21, 2019 How much smaller is it? The adaptor looks to be made of rubber so there is some leeway for fit. Quote Link to comment Share on other sites More sharing options...

Tom King Posted March 21, 2019 Report Share Posted March 21, 2019 Years ago I needed to do something similar. I don't remember what it was for. I do remember how I did it though. The 4" pipe end was soaked in boiling water, and the metal outer (metal) part of a No-Hub fitting was put around it while it was still soft, and the screws tightened. It actually did a very pretty job of it. https://www.plumbingsupplynow.com/4-heavy-duty-no-hub-coupling-452011h?gclid=CjwKCAjw7MzkBRAGEiwAkOXexLl3A4_-3DQXyQA415IX_MPmHfIhleOO7UsrpffDHyq2iIo7TEBIBxoCm-sQAvD_BwE Quote Link to comment Share on other sites More sharing options...
SteveKoz Posted March 21, 2019 Author Report Share Posted March 21, 2019 Thanks for the replies. I already purchases 6" blast gates which fit great with the 6" SDR35 pipe. I also have the 6" to 4" SDR reducers. I have a thin wall 4" PVC pipe that fit inside the reducer and could use that as long as the flex hose will fit over it. Waiting on delivery of the flex hose. I would prefer something with threads on it which should hold the hose on the fitting more secure. I am aware of some of the differences between SDR35 and SCH40. First one that caught my attention was the price.. I'm actually heading out tomorrow with the inlet section of my Oneida V3000. Just got delivered yesterday. Someone posted where they used a 6" to 6" adapter that fit snug into the Oneida inlet port. The 6" to 6" SDR adapter is too small..rattles around. Guess the next problem....I mean challenge... if the Schedule 40 fits the Oneida inlet port adapting the Sch40 to the SDR35 pipe. I'm seeing a big rubber Fernco connector in my future.

Brendon_t Posted March 22, 2019 Report Share Posted March 22, 2019 Holy Crap. Howdy Dave. Been a minute. OP, I bought a handful of them at Rockler a while back. I think they go with their Dust Rite system. Quote Link to comment Share on other sites More sharing options...

This particular gate used to rattle about halfway closed for some reason. I used the threaded hole where the lock knob used to be to hold the wood, counterbored the piece of wood and epoxied in a magnet. Seriously, it’s not as elaborate as it sounds. Now the door drags against the magnet and stays in whatever position I happen to put it in. Quote Link to comment Share on other sites More sharing options...
Mark J Posted March 22, 2019 Report Share Posted March 22, 2019 If you have a short section of PVC pipe/adator it is possible to gently reduce the outside diameter or increase the inside diameter by turning on a lathe. Mount in Cole or Longworth. Scrappers work best. Light cuts and frequent trial fittings. Quote Link to comment Share on other sites More sharing options...
SteveKoz Posted March 23, 2019 Author Report Share Posted March 23, 2019 The Schedule 40 coupler did not fit into the inlet of the Oneida. I purchased a rubber fernco that looks like it will work. Still need the 4" adapter with threaded hose end. Does anyone have an amazon part that they have used? The one from Grizzly is for a Schedule 40 pipe which I don't think will work with thin wall PVC? I've got these two.. Any idea which one has a better chance of fitting? :) https://www.amazon.com/gp/product/B00AU0FVJA/ref=ox_sc_act_title_2?smid=A1UAD3GC6ZP026&psc=1 https://www.amazon.com/gp/product/B00AX5I9XC/ref=ox_sc_act_title_3?smid=ATVPDKIKX0DER&psc=1 Thanks.
