You can connect pipes without glue by using inner tubing, tapes, and threading. Mechanical Connectors and RTV Silicone could also be used. Each of these methods has a different process but can be done easily.

Want to know more in detail? We’ve put together a guide on how to connect your pipes without PVC glue.

So let’s get to it!

How To Connect PVC Pipe Without Glue? [5 Different Ways]

Joining and capping your PVC pipelines without glue can be quite the challenge. But fret not! There are several alternatives to PVC glue.

All of these choices ensure that the pipes don’t leak in any way. We have provided a detailed step-by-step process of how to install your pipes without glue. 

So let’s get into the grimy details!

Method 1 of 5: Inner Tubing

For this method, all you require is an old bicycle inner tubing.  We have curated a step-by-step process on how to fit the inner tubing for your convenience.

Step 1: Cut Off The Tubing

First, cut off a sizable portion of the tubing. The length of tubing required will depend on your pipe length. Make sure the tubing length is a bit longer than the pipe.

This requires using sharp tools, so make sure you have the proper box-cutter or knife.

If you’re unsure about which box-cutter to choose, take a look at our picks below-

Box-cutter 2

Step 2: Stretch The Tape Over The Pipe

It’s worth mentioning that inner tubing is a bit tough to stretch. Once you’ve managed to stretch it over the pipe, push the fitting on top.

It’ll be a bit difficult to do so, but keep on pushing. 

After placing the fitting on, stretch the remaining bit of tubing over the fitting. Ensure a proper seal by turning the connection on. And you’re done!

Method 2 of 5: Gorilla-Tape Strip

For this, you’ll require Gorilla Tape and an Anti-cutter/Precision Tool Knife. Now all you need to do is just follow the steps accordingly.

Step 1: Cut The Tape

Cut ⅓  of an inch strips of Gorilla Tape to tape around the rim. Remember to cut it lengthwise as you’ll apply the tape lengthwise across the rim.

Step 2: Fit On The Inner Rim

After applying the tape on the rim, make sure to press along the edge. Applying pressure across the inner pipe’s rim allows maximum adhesion.

Remember to apply the tape on the outside as well as the inside of the pipe. This increases the size of the pipe diameter ensuring a snug fit.

Step 3: Push To Fit

Next, push the fitting pipe on top of the taped pipe. This will require some strength as your pipe has increased in size.

There should be no leaks as the connection is tight. You can only remove this using pliers to dig it out.

Method 3 of 5: Threaded Pipes

This method requires you to thread the pipes. You will require a PVC threading tool, vice-clamps, and a rag to carry it out.

Sometimes you may need to cut the pipes to sizable portions. This can easily be done by using a Jigsaw to cut the ductwork/pipe.

Now, let’s get to the process.

Step 1: Secure The Pipe

First, clamp your pipe so that it becomes stable. A loosely clamped pipe won’t have even thread along its rims.

Step 2: Insert The Pipe

Next, insert the threading tool on top of the pipe. Turn the tool clockwise while pushing down on it. Stop only when the tool’s edge hits the end of the pipe.

Step 3: Remove Properly

For the final step, remove the clamp to take the pipe out. Don’t forget to use a rag to clean the area. 

This ensures it doesn’t have any loose threads.

Method 4 of 5: Mechanical Connectors

This is one of the most popular alternatives for PVC glue in domestic settings. If you follow the instructions properly, you shouldn’t face difficulties.

Step 1: Debur, Clean, And Reverse

Clean the outside of the pipes beforehand. Then open the small washer/compression nut stack properly.

Next, reverse the washer, rubber washer, and nut onto the pipe for a snug fit.

Step 2: Slide it In

By pressing against the washer, slide the joint body in. Next, before making contact with the joint, slide the washer and bolt through the connecting pipe.

This should complete your settings.

Method 5 of 5: RTV Silicone

For this, you’ll require a rubber O-ring and a steel ring that crimps on the inner PVC. It’s important to note that O-rings require proper maintenance. This is the perfect replacement for your PVC Solvent or glue.

Here’s what you need to do-

Step 1: Clean and Trim

Clean the pipe before starting. Now, trim ¼ from the tip of the silicone caulk’s tube. Finish off by punctuating the seal with a sharp object.

Step 2: Use A Caulk Gun

Insert the silicone caulk tube in the caulk gun. Afterward, push the plate up against the rim of the tube.

Step 3: Force it In

Press the trigger to push the push plate into the tube. Determine the gap at a PVC joint and seal it placing the tube’s tip on the top.

Now, press the button repeatedly until the silicone tip appears. Slide the tip of the tube along the seam to apply a bead of silicone.

Step 4: Finishing touches

Finally, wet your finger with water. Then run your wet finger along the seam to smooth the silicone texture.

This is how you use RTV Silicone Sealant to connect pipes.

In conclusion, this is how you join PVC pipes without glue. All of these methods ensure a snug fit. Otherwise having faulty pipes would lead to flooding.

This is why it’s imperative to insulate your duct and pipework
