How to make a silencer out of pvc pipe


Do you want to know how to make a silencer out of PVC pipe?

It’s actually easier than you might think. In this blog post, we’ll walk you through the steps of creating a simple yet effective silencer out of PVC pipe.

Not only is it easy to make, but it’s also inexpensive, making it a great option for those who want to make their own silencer. Read on to learn how to make a silencer out of PVC pipe.

The materials you will need:

  •  First, you’ll need a piece of PVC pipe(the length of the pipe should be about twice the size of the gun barrel) usually between 3-5 feet in case you mess up as well diameter of pvc pipe needs to match diameter or slightly bigger than barrel diameter.
  • Depending on the size of your gun, you may need to adjust the diameter of the pipe accordingly.
  •  You’ll also need some PVC glue/PVC cement
  •  A few end caps for the pipe that fit the PVC
  •  Drill with a metal bit to make the holes in PVC
  •  Some metal wool or steel wool or other absorbent material to absorb sound
Once you have all your materials, it’s time to start building your silencer.

The process of how to make a silencer out of pvc pipe:

Making a silencer out of PVC pipe is a relatively simple process that will give you a high-quality, custom-made silencer. Here are the steps to make your own.

Gather Your Supplies from above

Gather everything you will need from the above list to complete this task and make the silencer

Cut the Pipe to Size:

Measure and mark the pipe where you would like to cut it. Cut along the line with a hacksaw or other cutting tool and then sand down any rough edges.

Add End Cap:

Place the end cap onto the end of the pipe and secure it with PVC cement. Next start by gluing the two end caps onto either side of the PVC pipe.
Make sure they’re securely fastened, as this will be crucial for containing the sound. Allow the glue or cement to dry before moving on to the next step.

Drill Holes:

Use a drill to make several small holes in the side of the pipe. The number and size of holes will depend on the type and size of the gun that you are using, but aim for 1/8-inch holes spaced out around the circumference of the pipe.
This needs to be done at the end of one of the end caps. This hole should be just large enough for the gun barrel to fit through.

Fill Pipe with Absorbent Material:

Choose an absorbent material that is suited to the size and type of gun you are using and fill the pipe with it until it is 3/4 full. Some good options include metal wool, steel wool, cotton balls, or packing foam. This will act as a sound dampener when the gun is fired. Make sure it’s packed tightly in there!

Insert End Cap:

Place the end cap onto the open end of the pipe and secure it with PVC glue or cement. Allow the glue or cement to dry completely before use.

Test it Out:

Attach the silencer to your gun and test it out at a shooting range or similar safe area. You may have to adjust the number or size of holes if you find that there is too much sound escaping from the silencer.
Once your silencer is perfected, you can enjoy quieter shooting sessions without having to purchase an expensive, store-bought silencer.
Once you have completed these steps, your silencer is ready to use! Enjoy shooting without the loud bangs.With a few supplies and some simple instructions, you just created your own customized PVC pipe silencer in no time!

Benefits of PVC pipe Silencer:

  • Using PVC pipe to make a silencer is a great way to achieve the same sound dampening effects of a regular silencer without having to purchase expensive, specialist parts.


  • PVC pipes are widely available, relatively inexpensive and can be cut to any length or diameter desired. The rigid, cylindrical shape of the pipe also allows for easier adaptation and customization to the shooter’s needs.


  • The sound-dampening effect of a silencer created from PVC pipe is superior to that of a regular silencer due to the density and material composition of the pipe itself.


  • The layers of PVC pipe act as a barrier between the noise generated by the firearm and the environment around it, allowing for a greater reduction in sound levels when shooting.


  • Furthermore, the interior walls of the pipe are textured, which helps reduce turbulence and further increases the sound dampening effect.


  • Finally, building a silencer out of PVC pipe is relatively easy and requires minimal tools or technical knowledge. All you need is a basic saw, drill and some sandpaper to shape the silencer to fit your firearm.
With a little bit of work and some spare time, you can construct a perfectly functional silencer from scratch in no time. This makes the process of building your own silencer much simpler and more accessible than if you were to purchase an off-the-shelf model.

The Disadvantages of using PVC Pipe:

Using PVC pipe to build a silencer is not an ideal choice for a variety of reasons. PVC is an inexpensive and widely available material, but it does not offer many advantages for use in silencers.

  • In terms of durability, PVC is not as strong as other materials like steel or aluminum, which means it can crack or break with prolonged use.


  • Additionally, while PVC is resistant to corrosion, the material may still degrade over time due to its inability to resist heat and pressure.


  • The performance of a PVC-made silencer also leaves something to be desired. The design of a PVC silencer usually requires you to fill the pipe with some type of absorbent material like sand or polyester batting.


  • This absorbent material tends to become clogged quickly and requires frequent replacement, making it difficult to maintain peak performance.


  • Additionally, the hollow nature of a PVC pipe also makes it more susceptible to back pressure, which can reduce the overall performance of the silencer.


  • Finally, using a PVC pipe for a silencer can also be difficult from a legal standpoint. Because of their affordability and accessibility, these makeshift silencers are often associated with criminal activity and can attract unwanted attention from law enforcement.


  • There are also some states that have stricter regulations on home-made silencers, so using a PVC pipe for a silencer could land you in trouble if you are not careful.
In conclusion, using a PVC pipe for a silencer is not the best option due to its lack of durability, subpar performance, and legal implications.
If you are looking for a reliable and effective way to reduce sound from your firearms, then there are much better options available on the market today.


In conclusion, making a silencer out of PVC pipe is an easy and cost-effective way to build a noise-reducing device. Although this method will not provide the same noise reduction as more expensive options, it is still effective at reducing noise.
The advantages of this method include its low cost, ease of assembly, and adaptability to a wide range of firearms. With the right materials and proper construction techniques, anyone can create a reliable silencer from a few pieces of PVC pipe.
Ultimately, making a silencer out of PVC pipe is a great option for those looking for a relatively simple and inexpensive way to reduce gun noise.
