Wondering if there is an alternative to glue when connecting PVC pipes? The answer is yes, and there is more than one method to choose from, especially in a home setting. Many of these methods are also quick, easy, and very low-budget ways to connect PVC pipes without glue.
In this article, we cover six alternatives to glue, as well as what PVC pipe is and the benefits of using PVC pipe compared to other pipe materials. So read on to find out which glue alternative is best for you.
How to connect PVC pipe without glue
What is PVC pipe?
The combination of letters PVC stands for polyvinyl chloride, which means that PVC pipes are made of a combined material of plastic and vinyl. PVC was developed by accident when Dr. Waldo Semon, an employee of BF Goodrich, tried to invent a method of bonding metal and rubber in 1925.
His discovery remained virtually unused for nearly a decade. It was in the late 1930s that PVC proved to be very shock absorbent. This led to the use of PVC in long-life tire treads. PVC pipes were invented two decades later, when a machine called an extruder was first used to push them into hollow pipes.
The benefits of PVC pipes
There are many benefits to using PVC pipes. They are very resistant to corrosion, unlike old iron pipes. Not only are they invulnerable to external corrosion when underground, they are also resistant to internal corrosion. The rate of pipe breakage is the lowest compared to pipes made of cast iron, concrete, ductile iron, steel or asbestos-cement.
PVC pipes also have excellent resistance to chemicals that can eat through other pipe materials. The smooth inner lining of PVC pipes reduces resistance to water flow, resulting in fewer blockages than, for example, clay or copper pipes.
Other benefits of PVC pipes include faster installation times, high water transfer rates, leak-free joints, long life and lower costs. The long life of PVC pipes means efficient operation, which reduces the need for maintenance and continuous pipe work.
Where are PVC pipes used?
The properties of PVC pipes make them versatile and suitable for many purposes. They are used in sanitary installations. They can transport water and gas as well as handle chemical waste. PVC pipes can be used in underground projects as well as above ground inside buildings.
They can even be used outside the soil as long as they include UV inhibitors and stabilizers to protect against UV radiation. They will also need to be painted with water-based latex paint when used outdoors above ground.
In addition to water distribution and chemical waste handling, PVC pipes can be used, for example, in building infrastructures in air exhaust and ventilation systems and cable insulation. PVC pipes can be used in agriculture for irrigation water, sprinklers and spraying pesticides and fertilizers.
How to connect PVC pipe without using glue?
There are several methods you can use connect the PVC pipes without glue. To help you decide which alternative is best for you, we’ve included information below on six simple glue-free methods for connecting PVC pipes.
Method 1 – Threaded PVC pipe
There are different types of thread options for PVC pipes. Most of the common threads have sharp internal threads inside a small circular metal object. Threading is very simple and all you need is a rag, a pipe vise and a clamp vise. This video is great for a visual demonstration of how to connect threaded PVC pipes.
- Start by wrapping a cloth or cloth around the PVC pipe. Secure it in place with the vise.
- Next, place the threading tool on the edge of the pipe and turn clockwise. As you turn, press the threading tool into the pipe until the edge touches the end of the pipe.
- Remove the clamp. Finish by cleaning the new threads using the cloth.
Method 2 – Taping
Using strong, durable tape, such as gorilla tape or duct tape, will give you a seal that should last a long time and not leak.
- Start by cutting two small pieces of tape, about a third of an inch long.
- Next, place a piece of tape lengthwise inside the pipe and then over the lip to the outside of the pipe.
- Repeat the second step with the other piece of tape at the same end, but on the opposite side of the pipe.
- Push the pipe into the fitting and press into it. You need to press it as firmly as possible.
- Test the connection by trying to remove the pipe from the fitting. Since you increased the diameter of the pipe with the tape, it should be extremely difficult to remove.
- Wrap a layer of tape around the PVC joint to improve the seal.
Method 3 – Old bicycle chamber
This method is inexpensive, will hold liquid, and is unlikely to require you to visit a hardware store. If you don’t have an old tube ready, many local bike shops will give you a used tube for free.
- First, cut a piece of the inner tube. It should be slightly longer than the depth of the fitting connector. Depths will vary, but in most cases, about two inches of inner tube will be sufficient.
- Next, slide the length of inner tube you cut over the end of the PVC pipe. It should be very comfortable. Make sure it hangs slightly over the lip.
- Insert the PVC pipe into the fitting. You will need to push hard as it will be extremely tight.
- Bend the hanging section of the inner tube over the end of the fitting.
- In the end, check the connection. It’s one of the best you’ll get using improvised components, and the inner tube will serve as a gasket.
Method 4 – RTV Silicone
Using silicone is a quick and easy way to seal PVC pipes without glue. You must ensure that the pipe is completely dry before applying the silicone.
- To prepare the pipe, remove all dust and debris using a damp cloth.
- Add a bead of silicone along the seam or gap of the PVC piping. Go around the perimeter of the hole.
- Wet your finger and smooth the silicone by running your finger over it.
Method 5 – Mechanical connectors
Using mechanical connectors is a popular way to connect PVC pipes in home environments. They are simple to use and affordable. You can find information about mechanical seals in this video.
- Start by deburring the pipe with wire wool and remove any dirt with a damp cloth or towel.
- Turn the nut, washer, and rubber washer onto the section of pipe you want to connect. The rubber washer must extend at least 1.5-2 cm beyond the pipe and fit perfectly.
- Slide the joint body onto the pipe, securing it to the rubber washer.
- Slide the nut and washer through the connecting pipe before contacting the joint.
- Tighten the screw using a plumber’s wrench.
Method 6 – O-ring fittings
When you use this method to connect the PVC pipe, the O-ring provides a watertight seal and the steel ring stretches over the inserted PVC pipe.
- The butt should have a bevel of about 12 to 15 inches. Refer to the O-ring joint chamfering appendix and mark the locations.
- Next, clean the socket and ring groove with a clean cloth. The box you purchased the O-ring in should have detailed cleaning instructions.
- Check that the rubber ring is evenly distributed on the ring groove by running your finger around the ring.
- use lubricant on the tap end. Pay special attention to the chamfered area.
- Align the spigot and plug and apply even force to push the stopper into the socket.
How to undo PVC adhesive and fittings?
If you want remove the glue from the PVC pipe connections, you can break the bond by heating the plastic. The temperature will need to be between 250 and 350 degrees Fahrenheit. At this temperature, the glue and plastic will soften and you will be able to pull the pipe out of the fitting.
This method will also work to loosen stuck fittings. The heat will soften the plastic pieces and allow you to remove them. However, if the temperature is too high, it will break the fitting, so watch your temperature carefully.
Conclusion
If you want to connect PVC pipes at home without using glue, there are several options to choose from. Most of them are not only quick and easy to make, but also low cost.
