Best gluing technique for adding PVC ports

[Mike Baker]

Good morning guys. I know I have seen this topic before but checking to see if any other fresh ideas have surfaced. I have a PVC port tube I want to glue in to my MDF baffle. I will have a double thickness of material at that point. I am thinking I will use a 2-part epoxy for the joining. Comments or suggestions?

Locktite PL Premium 3x

Another vote for PL Premium. It's a great adhesive, just don't get it on your skin, it takes days to peel off.

I've done both the PL and epoxy - project dependent.

I'll try the PL Premium. Thanks

Spread it out a little too, to give it more surface area to adhere too. Might want to rough up the surface of the PVC as well.

One vote for hot melt glue. Kinda the neat thing is, if you use a plastic port with a flange mounted from the front w/o screws, you can lay a light bulb (60w) on the opening for a while and it will warm the glue enough that you can wiggle it back out.

5' epoxy for me

Whatever glue you choose, be sure to prep the PVC by wiping it with a good solvent, then let it dry thoroughly. I use mineral spirits.

Gorilla glue. The foaming kind.

Frankly, I've only built three pairs at this point in time and I just use whatever Titebond I'm using at the time. As far as I know,,,, they're still all stuck.

YMMV, Mark

I've been using caulk to install my PVC ports for over 20 years. I use the 100% silicon type, like the kind you'd use on a bathtub. I always double up the thickness of wood around the port to give it a nice mechanical hold, then goop it up with caulk, install the PVC, and wipe away the excess. I've never had any problems.

I use titebond in MFD with roughened up PVC, epoxy with a loose fit in MDF, and my preference is PVC glue in a PVC flat stock. I screw the PVC assembly to the MDF or hardwood.

I tend to use 2 part epocyll















































































































































































































I tend to use 2 part epoxy.... it is important to degrease it with alcohol or some solvent like was mentioned. But for a truly solid joint, scuffing the shine off of the surface with sandpaper will give the glue some roughness to hold on to.
