Thread: 4" PVC to 4" flex hose adapter needed

  1. #1

    4" PVC to 4" flex hose adapter needed

    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!

    A standard 4" PVC coupling will work if your hose OD is slightly larger than the coupling ID. I used a Dremel with a ball bur to cut some internal threads. Be sure to check the thread rotation several times before you start cutting!

    Now that I have a 3D printer I used it for the last one I made.
    Beranek's Law:

    It has been remarked that if one selects his own components, builds his own enclosure, and is convinced he has made a wise choice of design, then his own loudspeaker sounds better to him than does anyone else's loudspeaker. In this case, the frequency response of the loudspeaker seems to play only a minor part in forming a person's opinion.

    This is what I use from Grizzly. It screws into 4" flex and will slip snugly into regular schedule 40 PVC.
    Grizzly has had everything I've ever needed for DC fittings and at a great price.

    Hope this helps,

    Thank you. This is what I was looking for. Wish amazon carried. Would save on the shipping.

    I've used an ungasketed spiral pipe connector before. Slips into the pvc and the flex hose

    Anything from Grizzly is available on amazon. Just search by Grizzly and the part number. https://www.amazon.com/s?k=Grizzly+D4261&ref=nb_sb_noss

    The Prime price includes shipping cost though LOL

    I'm using these:

    They're a bit slopping inside DWV pipe so I use a piece of the thicker green pipe. They would work fine inside DWV pipe with a couple wraps of painter tape.

    Still a few dollars less getting through Amazon.

    Question Did you try a heat gun?

    I suggest you to purchase something at close size and use a hot gun to mold it appropriately. For PVC I found something around 330 degrees C is very fine to put it at maleable state with no burn. Quick and easy.
    All the best.

    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..One is the Grizzly. Any idea which one has a better chance of fitting?
