Tnisesm Silicone Vacuum Hose Kit 134-Piece — 6.6 ft Tubing (6 Sizes) & 12 Connectors, High-Temp/High-Pressure

The Tnisesm 134-piece silicone vacuum hose kit is a complete automotive vacuum line set featuring six silicone tube sizes, twelve connector styles, and high-temperature, high-pressure performance for engine bay and DIY fabrication work.

This kit bundles long runs of reinforced silicone vacuum hose with a broad selection of nylon connectors so you can route, repair, or prototype vacuum and coolant-air lines without searching for individual parts. Designed for workshop convenience, tubes are rated for wide temperature ranges and offer higher burst and working pressures than generic rubber tubing.

What sizes and components are included in the kit?

The kit contains six lengths of 6.6 ft (2 m) silicone tubing in common inner diameters and 128 assorted nylon connectors covering 12 connector styles. That gives you plenty of hose and fittings to handle multiple projects or several repairs.

• Hose inner diameters: 3mm (1/8"), 4mm (5/32"), 5mm (3/16"), 6mm (1/4"), 8mm (5/16"), 10mm (3/8").
• Outer diameters: 7mm, 10mm, 11mm, 12mm, 14mm, 16mm respectively.
• 128 nylon 66 connectors in 12 different styles for tees, reducers, elbows and joiners.

How tough is the silicone tubing under heat and pressure?

These hoses are reinforced silicone with a 3mm wall thickness and built to resist high temperatures and pressure. They tolerate extreme cold and heat and have clearly defined working and burst pressure ratings for safe workshop use.

• Temperature range: -76°F to 392°F (-60°C to 200°C) for reliable performance in engine bays.
• Working pressure: 43 PSI; burst pressure: up to 130 PSI at room temperature (100 PSI at high temp).
• Connectors made of heat-resistant nylon 66 rated to 240°C (460°F) for stable joints.

Which applications are these hoses best suited for?

They work well for any general-purpose air or water transfer in automotive, marine, or light industrial settings. The set is aimed at vacuum line repair, intake routing, coolant bypasses, and custom turbo/intercooler mock-ups — not for fuel or oil transport.

• Ideal for vacuum lines, boost reference hoses, intake plumbing, and radiator bypass routing.
• Useful in custom fabrication: turbo charge and intercooler mock-ups, sensor fittings, and prototyping.
• Not intended for gasoline, diesel fuel, or engine oil — silicone here is specified for air/water only.

How do these parts make installation and maintenance easier?

The long 6.6 ft lengths and wide range of connectors reduce the need to splice multiple short pieces, while reinforced walls resist kinking and collapse. Using purpose-fit connectors and common diameters speeds up repairs and creates neater, more reliable runs.

• Long continuous lengths cut down on joints and potential leak points.
• Multiple connector sizes let you build tees, reducers, and angled runs without specialty tools.
• Reinforced walls help maintain airflow and resist vacuum collapse under load.

Who is this for: This Tnisesm kit is aimed at DIY enthusiasts, home mechanics, performance hobbyists, and small-shop technicians who need an all-in-one supply for vacuum and air/water routing. If you frequently fabricate or repair intake systems, vacuum manifolds, boost control plumbing, or cooling bypasses, the variety and length in this set simplify work and reduce trips to the parts store. It’s not a replacement for fuel-rated hoses; use it where air or water transfer is required.
