EWOJUYE Silicone Vacuum Hose Kit 6pcs 5ft — Black, 6 ID Sizes with 64 Connectors & 24 Clamps, Heat-Resistant

EWOJUYE's 6-piece silicone vacuum hose kit is a complete automotive vacuum-line repair set that includes six 5 ft hoses in multiple inner diameters, 64 connectors, and 24 clamps to rebuild, replace, or customize vehicle vacuum lines.

This kit brings together a range of silicone vacuum hoses, multiple connector shapes and sizes, and matched clamps so you can tackle vacuum-line repairs on engines, HVAC systems, brake boosters, and vacuum-routed accessories. The hoses are heat- and cold-resistant silicone rated for -40°C to 250°C with working and burst-pressure specifications suitable for most automotive vacuum applications. The set is supplied in black and sized to cover common factory line diameters, letting you cut to length and assemble secure runs with the included fittings.

Which hose sizes are included and how long are the lines?

The kit contains six hoses, each about 4.92 ft long, covering inner diameters from 1/8" to 3/8" so you can match factory and aftermarket vacuum ports. Lengths are sufficient to cut custom pieces for complex routing or multiple repairs without needing additional purchases.

• Hoses: 1/8" (3 mm), 5/32" (4 mm), 3/16" (5 mm), 1/4" (6 mm), 5/16" (8 mm), 3/8" (10 mm) — each 4.92 ft long
• Cut-to-fit lengths for custom runs, tees, and splices
• Black silicone for discreet installation under the hood

What connectors and clamps are supplied, and which fit common vacuum fittings?

This kit includes 64 connectors in a variety of diameters and configurations—straight couplers, step adapters, and short-length fittings—so you can join matching or different-size hoses. Also supplied are 24 hose clamps in six sizes to create tight seals and reduce the chance of vacuum leaks under pressure or temperature swings.

• Connectors: assorted OD/length combinations across 12 connector types to cover common OEM ports
• Clamps: 4 pieces each of 9, 10, 11, 12, 14, and 16 mm diameters for secure hose retention
• Use clamps on high-stress joints or where fittings slide over barbed ports

How durable are the hoses — temperature, pressure, and material performance?

The hoses are silicone, engineered to resist aging from repeated heating and cooling cycles so they stay flexible in winter and stable in high under-hood temperatures. Working pressure is rated at 43 PSI with burst ratings listed for room and high-temperature conditions, making the lines suitable for most vacuum and low-pressure fluid tasks (air/water only).

• Temperature range: -40°C to 250°C for hot and cold resilience
• Working pressure: 43 PSI; burst pressure: 100–130 PSI depending on temperature
• Wall thickness (~3 mm) for a snug fit on barbed fittings and good sealing

Are there any usage limits or installation notes I should know?

This vacuum tubing is intended for air, water, and other non-petroleum fluids. Do not use these silicone lines for fuel, oil, or other petroleum-based liquids — they are not formulated for hydrocarbon service. For best results, confirm the media and size of original lines before replacing them, and secure connections with the included clamps where needed.

• Not suitable for transporting petroleum, engine oil, or fuel
• Use the proper connector size for the port and trim hose ends squarely for a clean seal
• Clamp higher-stress points and test for leaks after installation

Who is this for: This EWOJUYE silicone vacuum-line kit is designed for automotive technicians, DIY mechanics, restoration enthusiasts, and fleet maintenance staff who need a versatile, ready-made supply of vacuum hoses and fittings. It’s especially useful when repairing vacuum routing, replacing brittle factory lines, or customizing vacuum manifolds where multiple diameters and connector types are required.
