    Default How to glue PVC and plastic

    Hello, I have a sander with a plastic dust port that I would like to glue a PVC tube which takes a standard vacuum hose.

    I don't want to melt the plastic.

    It is a PVC pipe to go into a tapered plastic female fitting, so it needs some filling too

    Can anyone please advise the best way to do this?
    regards,

    Dengy

    Purbond Polyurethane Glue, single pack waterproof glue

    A single pack, fully water proof, moisture curing polyurethane adhesive. Purbond is an extremely economical polyurethane glue. Purbond glues almost any thing to almost anything. We have glued up samples of several hundred Australian timber species with Purbond, including the difficult ones like Huon Pine, Jarrah and Beech and provided the joint is done in accordance with the instructions, when we tear the Purbond joint apart, the wood always fails first. This Purbond glue likes to be clamped and clamped hard. Freshly cut wood surfaces, and a little moisture in the joint (only a little!) is how we get great joint strength from Purbond adhesive. A little goes a loooong way. Purbond is also used to glue stainless steel splash backs to MDF, PVC duct to concrete walls, even an over coating of concrete over a deteriorated concrete floor. Almost anything to anything.

    Sikaflex or other type of sealant - sticks to just about everything and fills gaps so is perfect for a lap joint, but I wouldn't use it for a butt joint. don't forget to mask anything you don't want it on.

    Comes in a tube like silicon caulking from any hardware store

    SIKABOND polyurethane glue from bunnings. it foams up, and sticks to anything. great glue as it fills up gaps. use it sparingly, as it foams up.

    Thanks for the suggestions everyone. Tried out the polyurethane glue, and boy , did it expand overnight. Unfortunately it overflowed into the parts that I needed to be clean and smooth - ruined the whole piece, so had to order another part from Rockler in the US. Hopefully it will get here in the next few weeks.

    Must admit that glue set like steel, adhered amazingly well.

    How do people use it on mitre joints with the amazing expansion and overflow - it must spread all over the parts next to the joint, both inside and outside of box joints?
    regards,

    Default Hot Glue Gun

    I've used a standard art and craft glue gun on my dust extractor. I was surprised by the strength of the bond. Cheap effective option and fairly easy to keep tidy.

    I know this thread is a little stale.

    but for most power tools you dont have to glue.

    Most of my power tools I have adapted to normal vac hose using 32mm electrical conduit and masking tape.

    For example
    a tool with an inside taper that is loghtly larger than the od of the 32mm pipe.
    I will build up the 32mm pipe with wraps of masking tape till it is a snug fit.
    Most will require two bads of 20mm tape.

    when you have adjusted both bands till they are faoirly snug...push it home hard and it will stay there.

    I did this on my metabo random orbit over 5 years ago...it has done a lot of hours and has never come out on me.

    Other tools heat forming the pvc pipe can solve many problems..on an outside fitting where you fit the pvc pipe over the tool apiture.....softening the pvc in boiling water then clamping it down in place with hose clamap while hot...will give a nice firm fitting that requires no glue...the hose clamps can be removed when cool.

    rubber hose and hose clamps can work too.

    Of all my many tools with made up vac hose connections..not one is glued......all could be very easily be removed with no damage.

    cheers
    Any thing with sharp teeth eats meat.
    Most powertools have sharp teeth.
    People are made of meat.
    Abrasives can be just as dangerous as a blade.....and 10 times more painfull.
