homemade silicone o-rings and tubing

Do your own O-
Rings and pipes made of silicone!
The object in this photo is a homemade diving camera shell made of silicone O-rings. (
My next note is the camera case)
Quick and Dirty explanation: inject silicone adhesive directly from the tube to a transparent vinyl tube with a caulking gun, let it solidify, blow silicone out with compressed air, and re-Silicon
Stick it together to form a ring.
If you want the pipe, blow it out before the silicone is cured. . .
Not only will this structure show how to make O-
Rings and pipes, but elaborate on how the silicone adhesive behaves so you can use it and make more!
The main material is the silicone adhesive in the tube used for the caulking gun. 1.
Different types of silicone.
DONOTUSE \"Silicone II\", it is not pure silicone and will not behave as expected as \"silicone I ,(
Or 100% silicone).
My favorite is the black silicone made by ACE.
Also great to clear GE Silicone 1. 2.
Remove vinyl pipes.
This is what you pump the silicone in, this is O-Ring and pipe. The \"I. D.
\"Or the inner diameter of the pipe will be\" O \". D.
\"Silicone O-
The ring you\'re making3.
For about a week of treatment, masking tape, compressed air, sharp knives, high quality caulking guns.
Push the silicone into the vinyl pipe using the caulking gun and squeeze it out!
You will notice that as the vinyl pipe is filled with silicone, filling will become more and more difficult due to the high viscosity of the silicone.
Fixing vinyl pipes to the top of the caulking tube requires considerable pressure. (
A nice caulking gun is worth the price here)
You may only be able to pump about 15 inch of the silicone into vinyl before it is no longer needed, and you will feel the vinyl pipe expanding from the pressure!
The pipe shown here has an I. D.
1/4, this is a very convenient size.
The only pipe size I have tried is 1/8 I. D.
Something 1/4 bigger than me. D.
I will be very careful. . .
But more in a minute.
At this point the vinyl tube is filled with uncured silicone and you can keep it strong or make the tube with the silicone itself!
What needs to be done is to re-apply the compressed air to the vinyl pipe, which will force the uncured silicone to return, and at the same time stick enough silicone to the inside of the vinyl pipe, so that, it will be a pipe when it is cured!
If you do this using compressed air, use the minimum pressure.
The reason is that the sudden explosion of compressed air through the pipe after the silicone is squeezed out will cause the uncured silicone film glued to the vinyl to \"ripple\" due to the intense turbulence of compressed air \". . .
As we wait for a cure, there is a little bit of extra information: The interesting thing about this approach is that vinyl tubing, while waterproof and elastic, does not stop the silicone in it from curing.
Vinyl does not form a good \"steam barrier\" and therefore allows curing.
Silicone treatment from the outside. The (solid)
If the silicone is left in a 1/4 vinyl pipe, it may take more than a week to solidify.
If anyone has an idea on how to speed up treatment, please let me know.
Silicone that has been blown through to make hollow pipes will take a night, maybe more.
The difference is that air can enter the inside of the pipe and help the pipe to solidify faster.
As an impatient person, it is difficult to wait.
The first few times I did these, I have been checking and checking.
The silicone near the end of the vinyl pipe will cure relatively quickly, and even half an inch of silicone will cure quickly because it is close to the open air.
Don\'t be fooled, there\'s still a way to go with silicone deep in vinyl.
If there is no other reason to test how curing is done, you may want to make several lengths of pipes at the same time.
Just cut a part of your test pipe and any other pipe should be the same.
If someone uses vinyl over 1/4 ID.
Let me know what\'s going on! ! ! (
My prediction is a long time to heal. . . )
The really interesting part is coming now! -
Remove the cured silicone from the vinyl pipe!
There are two ways to do this.
The compressed air method is only suitable for solid silica gel.
It looks simple: connect the compressed air to the vinyl pipe and blow it!
This method doesn\'t seem to work at first, after all you can\'t push the rope right?
But what happens is that compressed air causes vinyl to expand, so it is separated from the internally cured silicone, leaving a slight gap. . .
Compressed air works in the gap between silicone and vinyl and creates turbulence between them.
The sound of this happening is hard to describe, but it sounds like a latex balloon is pinched to make it scream loudly.
Silicone will flash out of vinyl without you doing a lot of things other than laughing at its simplicity. (
This joy is similar to the joy experienced when flying pasta monsters gave birth to pasta children. . .
The legend is the same anyway)
If your silicone is not cured, the whole thing will not work.
The second way to remove the silicone is to simply pull it out of vinyl by hand.
Because it shrinks when you pull a piece of silicone --
It would be wise to pull it apart from the inner wall of the vinyl pipe and come out.
You may find other ways to do this, I. e.
Water, etc.
It helps straighten out vinyl pipes if you use \"Rafa.
From the silicone that appears in vinyl, you now have O-rings! 1.
Cut the silicone rubber \"wire\" to the required size (circumference)2.
Make the cutting end flat and uniform as much as possible.
Silicone \"line\" is very flexible and soft: Pre-stretching it (By making O-
Small Ring)
If your O-
The ring is used to hold on to something.
The silicone should remain soft and soft for a long time.
Basically, you will use O-made with you-
Stick the end together with glue. 1.
Wrap both ends of the wire using masking tape.
Doing so prevents the silicone you use for fusion from entering O-ring. 2.
Use wider adhesive tape as a stand, O-ring. 3.
Apply some silicone on the other end of the wire.
Push the end together and lock the tape down.
In fact, only a small amount of silicone is used to blend the ends together! 5.
Keep the end of the tape parallel to each other, O-
The ring will be \"round\". Don\'t worry! 6.
Wait a night, bend the tape and clean the extra silicone from the joint, which should be very easy as the tape prevents the silicone at the joint from sticking to O-ring.
This federation is in O-
But the silicone is very soft and does not affect the sealing performance.
Good luck to you! (
My next task is how to make a dive camera shell! )
