Multipurpose Vacuum Line Kit,6PCS 5Ft Vacuum Hose

This comprehensive kit is built to handle vacuum and low-pressure air or water duties across a range of automotive and DIY piping needs. Each hose is made from durable black silicone rated for temperatures from -40°F to 392°F and pressure tolerance up to 130 PSI. The set contains six hoses in graduated inner diameters and an assortment of connector fittings so you can cut, join, and route lines to suit brakes, emissions plumbing, HVAC lines, vacuum accessories, and workshop projects.

What hose sizes and quantities are included?

The package includes six 5-foot silicone hoses in these inner diameters: 1/8", 5/32", 3/16", 1/4", 5/16", and 3/8". You also receive 64 assorted vacuum-line connectors to join or step between sizes, providing flexibility during repairs and custom routing.

• Six hoses, each 5 feet long, covering 1/8" to 3/8" inner diameters
• Sixty-four connectors for butt joins, tees, reducers, and straight unions
• All components compatible for air and water transfer only (not for oil or natural gas)

How durable and safe are these silicone vacuum hoses?

OFBAND uses premium silicone with a uniform 3mm wall thickness to maintain consistent pressure handling and resist kinking or collapsing. They function reliably in a wide temperature range and are tested up to 130 PSI for suitability in many automotive vacuum and low-pressure systems.

• Temperature range: -40°F to 392°F for wide environmental tolerance
• 3mm wall thickness for consistent internal pressure integrity
• Maximum tested pressure up to 130 PSI for low- and medium-pressure applications

Can I customize lengths and adapt between sizes easily?

The silicone material is flexible and cleanly cuttable, so you can trim each 5-foot section to the exact length your project requires. The included assortment of 12 connector types lets you reduce, expand, tee-off, or splice hoses without additional tools beyond clamps if higher retention is needed.

• Easily trim hoses to custom lengths with standard cutting tools
• Assorted connectors enable reducers, tees, and straight couplings
• Use hose clamps or spring clips for secure mechanical retention when required

What should I avoid using these hoses for?

These hoses are specifically designed for air and water transfer and are not formulated for fuels, natural gas, oil, or combustion fluids. For safety and longevity, avoid exposure to harsh solvents or direct contact with petroleum-based fluids.

• Not rated for oil, gasoline, diesel, or natural gas transport
• Not intended for pressurized fuel lines or hydrocarbon service
• Compatible with engine vacuum systems, HVAC, and non-potable water routing

Who this kit is for: technicians, home mechanics, fabricators, and hobbyists who frequently build, repair, or prototype vacuum and low-pressure air or water lines will find this OFBAND kit practical. It’s ideal when you need multiple diameters on hand, plan to cut custom runs, or require a broad selection of connectors for step-downs, tees, and splices. If you work with fuels or pressurized hydrocarbons, choose a product specifically rated for those fluids instead.
