The smallest vacuum lines have a 3/16″ inner diameter (ID), and the biggest ones are typically 5/8″ ID hoses that provide manifold vacuum to a brake booster.
What size is vacuum advance hose?
Registered. Most automotive vacuum hoses use 1/32" smaller id than the od of the hose nipple to make a tight fit. 7/32 on 1/4, 5/32 on 3/16, etc.
Does engine vacuum hose size matter?
Smaller diameter vacuum hoses are often more maneuverable and flexible, not to mention lighter, and for certain applications there are performance benefits. Larger diameter hoses can pick up bigger debris, and with less likelihood of clogging. With shop vacuum sizes, 2-1/2″ is a good size for general cleanup tasks.Aug 8, 2018
How is automotive vacuum hose measured?
In the part number 10343-8-6, for example, -8 is the size of the fitting end connection, and -6 is the hose size. Hoses are measured by inside diameter, and tubes are measured by outside diameter, which is how they are differentiated from each other.
Is silicone vacuum line better than rubber?
Silicone hoses are more resistant to high temperatures. Over time, rubber vacuum hoses could crack or leak, but since silicone is able to withstand much higher temperatures than is typical for an engine, the heat is no match for them. This means that they aren't subject to the same kind of damage as rubber hoses.Jul 9, 2018
Are silicone hoses better than OEM?
With regular daily use and maintenance, the OEM hoses will function efficiently for many years, but eventually, heat and pressure will damage rubber hoses. Unless the car is used for high performance, the silicone radiator hose kits are not cost-effective.
Do silicone hoses improve 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. Silicone is a very stable material that acts almost like new, even when it's not.Aug 8, 2021
Do silicone hoses collapse?
Most thin silicone vacuum hose will collapse under vacuum causing a wide array of problems, including high emissions, incorrect gauge readings, poor gas mileage, and possibly even engine stalling.
What are vacuum lines used for in a car?

How do you measure hose size?
Hose sizes are designated based on the inner diameter of the hose, which is the measurement of the straight distance between the two furthest points on the inner surface of the tube. Virtually all hoses made globally are made on inch sizes even if given a metric size designation.
