What is the difference between silicone couplers and rubber couplers?

Silicone couplers offer better resistance and longevity over rubber. Rubber is cheap and easy to manufacture, which is why nearly all cars from the factory come with rubber couplers for intercooler and charge pipe connections that will wear out and cause boost leaks over time. By choosing silicone over rubber, you are performing cheap maintanence and preventing wear-and-tear failures.

How do I choose the right size for me?

If you are unsure what size you need, measure the outer diameter of the pipe or connection and match it the best you can to our table below. Be aware of the inlet and outlet sizing you need. If the exact size is not available, the next smaller size may suffice depending on the elasticity and application. Give us a call if you are still unsure!

What sets BOOST silicone couplers apart from the competition?

There are several factors that make our silicone truly unique. Every silicone hose or coupler that leaves our warehouse comes with an imprinted QR code that contains all of our rigorous testing protocols and burst pressures. You yourself can check and verify this information to ensure you are getting a silicone hose backed with the most thorough quality assurance standards on the market.

BOOST silicone also all come with a high Shore A hardness rating. Shore A hardness is a scale to determine the hardness of plastics and rubber, that scale goes from 0-100. Our silicone comes with a 70 (±5) Shore A hardness, which means it doesn't bend easily and retains much better shape under pressure or vacuum loads than the more commonly found 40 Shore A hardness in other silicone. So with our hardness rating, you can be sure you are getting proper function under boost or intake applications without deformation.

What type of clamps should I use on this coupler?

It depends on the size and the application you need the couplers for. If they are large and will handle boost like charge pipe connections, we recommend using T-bolt clamps or torque clamps - both of which we offer! Not only can standard worm gear clamps cut into the silicone, they are not designed to withstand consistent boost. However, for simple vacuum connections or water lines, worm gear clamps would be perfectly fine.

Some other things to consider...

Remember that the diameter always refers to the inner diameter, so be sure to consider that when choosing the size for you.

Clamp size is very important here, as you are essentially getting 3 clamps for one silicone piece. Remember, an easy way to figure out the right clamp size, multply the hose wall thickness by 2. That will give you the right size!

If you are having trouble finding the exact size, the next smaller size is usually enough to suffice.

BOOST not only delivers extremely high quality at a competitive price, but we have the testing to back our claims - and we can prove it. The BOOST products silicone products have achieved and many times even exceeded the quality of those compared to the ones made by well known manufacturers. This silicone is durable and proven to last through hard use. Many rely on the silicone made by BOOST products, so we have you covered for any level of build!
