Can I bend silicone?
This is, presumably, because it has a chip inside, and, as we all know, silicon does not bend. But when you talk to, among others, Gerhard Klink of the Fraunhofer Institute's “Group Polytronic Technologies” in Munich, he can show silicon bending. It is easy, really.
Easy to Install and Build With
In addition, silicone hoses are flexible enough to bend without cracking, making it easy to incorporate them into installations.
Note, as the diameter increases the flexibility of the hose also decreases. Silicone is a extremely flexible material compared to rubber, with the ability to maintain this flexibility over the lifespan of its use.
Formed hoses are highly customizable and aesthetically pleasing. These are produced by taking an extruded hose and then either vulcanizing or curing the hose to the desired shape (bends, flare ends, etc). Molded hoses can be shaped into simple or complex designs.
When it comes to manufacturing radiator hoses, the inner liner (of EPDM) is extruded first, then this “tube” is reinforced by a layer of knitted fabric (such as polyester, rayon or Kevlar) and covered by an outer layer of EPDM. Next, the hose is cooled in water and cut into lengths.

Silicone hoses benefit from superior flexibility compared to rubber. They maintain this flexibility over their lifespan unlike rubber hoses. This reduces the risk that your hoses will split, harden, or become dry rotted. Silicone hoses last practically forever and might possibly outlast your car.
Do silicone hoses increase performance? The reason people started manufacturing silicone hoses for the automotive industry in the first place was because silicone material offers such a valuable performance enhancement. So the simple answer is yes.
Do silicone radiator hoses leak?
Silicone is more expensive, so you must beware of the bargain bin silicone hose options. Cheap silicone hoses leak as they're typically not reinforced. They're also more likely to scuff and lose some of their luster.

Silicone tubing can be formed in several ways, but one of the most widely used methods is rubber extrusion. Rubber extrusion is the process of using a die to shape rubber materials into usable products.
A question that Viper Performance are frequently asked is “can I shrink or stretch the diameters of silicone hoses if I buy the wrong size?” The answer is simple “no.” Hoses are sold by internal diameter not external diameter.
First, try to get flexible hose close to the shape you need. Next, using a sharp hacksaw, carefully cut to length required.
Vaseline is not for coolant hoses, as coolant is best for that task.
Heater hoses are used to transfer the excess heat, in the form of engine coolant, from the engine into the heater core. Once the heated engine coolant reaches the heater core, it travels through small tubes inside the heater core.
Signs of a bad heater hose
Since your heater hoses play such an important role in your vehicle's cooling system as well, your engine may start to overheat when the hoses fail, causing engine damage which is expensive to repair.
Are silicone tubes soft?
This soft, flexible tubing is odorless, tasteless, and inert and is suitable for air, water, food, and beverage applications. It is made of silicone rubber which is nonreactive, flexible, and resistant to high temperatures.
Surgical tubing is frequently made from silicone or latex, and each material has its own benefits and disadvantages. Read More… Surgical Tubing Surgical tubing is used in sterile and medical environments to provide a flow path for liquids and gases. It can be made from natural or synthetic rubber.
“Rubber tubing” is a term that refers to hollow synthetic and natural rubber channels, or flow lines, that transfer or dispense liquids and gases. With their varying chemical compositions, rubber tubings' characteristics are quite diverse, which is advantageous for professionals who wish to engage tubing.
If you're cutting an unreinforced silicone hose that's smaller in diameter — up to approximately eight millimeters — you can use pliers, scissors or wire cutters to cut the hose. And, if you're cutting a reinforced silicone hose that's smaller in diameter, you can use a sharp blade or a parcel knife to cut the hose.
Once you use silicone tubing, you won't go back. Silicone is UV resistant; it does not age and deteriorate outdoors. The tube is very pliable and stretchy, allowing you to make tight turns and stretch it over barbs that are a little too big.
Any suggestions for making that bend without kinking the hose? Use fuel hose that was intended for motorcycles, amigo. Alternatively, find some extension coil springs that are slightly larger in diameter than the fuel hose and slide them over the hoses to prevent them from kinking.
Silicone Tubing is odorless, tasteless, and is NSF approvedd as food-grade at temperatures from -100F to 500F.
Silicone is one of the best compounds to use for high temperature purposes. It can endure exposure to high temperatures much better than most other materials. Typically, a high temperature silicone hose can handle temperatures that reach as high as 550° F.
We recommend rubber or silicone hoses for exhaust systems, because of their durability, flexibility, and strength. Rubber is more flexible, and is able to stretch and shrink repeatedly.
One of the things we find gets asked often is can your silicone hoses for used for fuel? The simple answer is no, standard silicone hoses are porous and therefore not suitable for oil or fuel.
Do silicone radiator hoses need special clamps?
When working with soft-surface hoses, like silicone, it's crucial that you use only special types of hose clampsspecifically designed for such uses. Most hose clamps have a long row of perforations inside the clamp; those notches are used to adjust the diameter of the clamp.
The best product to clean your silicone hose is with Dawn dishwashing soap and hot water. Our favorite is the blue bottle called Dawn Platinum Power Clean Dishwashing Liquid because it gets the quickest results with the least amount of soap.
Most manufacturers will recommend having your hoses replaced once every four years. Obviously this time period can be increase/decreased depending on different factors such as mileage, weather condition, etc..
Radiator Hose is made from a black heat resistant/smooth EPDM rubber with a High synthetic textile reinforcement.
When Should I Replace My Radiator Hose? There is no set lifespan for a radiator hose. On average, they should last for at least five years, but some will last longer, especially if you're vigilant about having your coolant changed and your vehicle maintained properly.
Does silicone melt? Yes, Silicone melt at high temperatures of around 1414 degrees Celcius.
While most plastics will begin to melt at high temperatures, silicone does not have a melting point and remains solid until combustion occurs. At high temperatures (200-450oC), silicone rubber will slowly lose its mechanical properties over time, becoming brittle.

Does silicone stand up to heat?
Silicone has a low thermal conductivity. This means it transfers heat at a much slower rate than some other materials, leading to excellent heat resistance. It can also be described as having good 'thermal stability' meaning it retains its structure and properties over a wide temperature range.
Silicones are well known for having a large expansion when they are heated (CTE) and also for their tendency to swell considerably when exposed to soluble liquids.
Silicon melts-with the right temperature. 1414°C (2577.2 °F) to be exact. It has a high melting point because its interatomic forces (covalent bonds) are pretty strong.
This material was found to lose not only its mechanical performance but also completely disintegrated upon heat exposure for 2 h at 200 °C.
Clean: Silicone is extremely easy to clean. It can be safely boiled to sterilize and can be cleaned in the dishwasher. Certain strong smelling foods can permeate silicone, although this can be easily remedied by boiling in water. Silicone also doesn't warp or damage under prolonged exposure.
Silicone is a very popular sealant in multiple industries. But a common question that pops up is; “can you use silicone as glue to bond materials in place?” The simple answer is yes, you can use silicone as glue.
Silicone caulk is excellent at water sealing and flexibility so it has its place in construction. There are two main places it never should be installed, wood or any painted surface.
Silicone, scientifically known as polysiloxane, lies in a gray area, but it's generally considered a rubber. It's a human-made elastomer (a polymer with elastic properties) that has the properties of both plastic and rubber.
Option #2: Silicone Glue
Simply apply a small amount of the silicone glue along the crack and carefully make sure that you've thoroughly covered every exposed piece. Then, give it a couple of hours to completely dry before using it or handling it.
Can I apply new silicone atop, or alongside old silicone caulk? It is recommended that any old silicone is removed. While new, freshly applied silicone can be applied & will bond to old silicone – the bond isn't as strong as if it were applied to a clean surface.
What can you cut silicone with?
A laser would be the best method followed by repetitive razor slicing in ever deeper cuts to avoid frictional deformation. Another method would be cold cuts by freezing the silicone and using a regular mechanical saw.
