[Durable Material] The vacuum hose is made of heat-resistant silicone resin material, which is resistant to aging, good flexibility, smooth surface, not easy to deform, good sealing property, high quality and durable. [Thick-walled structure] The thick-walled structure enables the vacuum tubes to work under high pressure conditions, and can connect and replace various pipes in high temperature conditions such as motors. After quality inspection, durable performance is guaranteed. [Specification] The set includes 6 pieces of black vacuum hose with an inner diameter of 3mm, 4mm, 5mm, 6mm, 8mm and 10mm (1 piece for each size). Working pressure: 43 psi. Burst pressure: 100 psi (high temperature), 130 psi (room temperature). Temperature range: -40 F to 428 F (-40 C to 220 C). [Installation steps] 1. Prepare the silicone vacuum tube of suitable size; 2. Remove the pipes to be replaced; 3. Install on the device. Select the silicone vacuum tube of suitable size, especially the inner and outer diameters of the tube. [Applicable] Silicone hoses are only used for air and water. Not applicable to natural gas and oil. Suitable for automotive vacuum lines, windshield washer fluid vacuum hoses, turbochargers, intake components, etc. Product Description Material: Silicone Resin What will you get in the box -1 x Vacuum silicone tube with an inner diameter of 3mm -1 x Vacuum silicone tube with an inner diameter of 4mm -1 x Vacuum silicone tube with an inner diameter of 5mm -1 x Vacuum silicone tube with an inner diameter of 6mm -1 x Vacuum silicone tube with an inner diameter of 8mm -1 x Vacuum silicone tube with an inner diameter of 10mm The advantages of our products: – Made of heat-resistant silicone material, it is resistant to aging, has good flexibility, smooth surface and is not easy to deform – Thick-walled design allows the vacuum tubes to work in high-pressure environments, which can connect and replace various pipes in high-temperature environments such as engines – Multiple sizes, good sealing performance, high quality and durable
