Description
USA Lab 8mm Rubber Vacuum Hose
Built for durability and reliability in demanding vacuum work.
Our 8mm Rubber Vacuum Hose is made from high-quality gum rubber with a thick, 3mm wall that holds a strong, consistent vacuum seal without collapsing. That makes it just as at home on a lab bench as it is under the hood. It fits securely on 5/16" to 3/8" barbed connections, flexes easily for tight routing, and resists the tears and punctures that come with everyday use.
Whether you are pulling a hard vacuum on a rotovap or routing a booster line in an engine bay, it gives you the durability and steady performance you can count on. Sold by the foot in 1 ft increments, so you order exactly what you need.
Purchased in 1 foot sections. Set the quantity to the number of feet you need. For vacuum and industrial use. Not a certified food-grade or potable-water line.
Gum Rubber Very Flexible Fits 5/16" to 3/8" Sold by the Foot
Tear-Resistant: Resists tears and punctures, so it holds up even with regular use.
Holds Its Shape: The thick 3mm wall keeps the line from collapsing under vacuum, up to 29 in. Hg.
Universal Fit: Seats securely on 5/16" to 3/8" barbed connections.

Where this hose earns its keep
- Lab vacuum systems: rotovaps, vacuum filtration, cold traps, desiccators, and vacuum ovens. The thick wall keeps flow steady under a hard pull.
- Automotive & small engine: brake booster and manifold lines, carburetor and emissions routing, and hooking up vacuum gauges.
- Industrial & shop: pump hookups, transfer lines, and general low-pressure vacuum plumbing. Easy to route and re-route.
Tip: add a hose clamp on barbed fittings for a leak-tight seal under full vacuum.

FAQ
Is this vacuum hose sold by the foot?
Yes. It is sold in 1 foot increments, so the quantity you order equals the number of feet you get. Order 10 for a 10-foot length.
What fittings does it fit?
It is sized for 5/16" to 3/8" barbed connections. With an 8mm inner diameter it stretches on snug, and a hose clamp locks it down for a vacuum-tight seal.
Will it collapse under vacuum?
No. That is what the 3mm wall is for. It is rated to 29 in. Hg at 72°F and holds its bore under a hard pull, so flow stays consistent between your pump and your equipment.
What is the temperature range?
-70°F to 180°F, which covers most lab benchtop and automotive engine-bay conditions. For sustained high heat or open-flame exposure, contact us about a higher-temperature material.
Is it food or potable-water safe?
This is a gum-rubber vacuum and industrial hose, not a certified food-grade or potable line. If you need a specific compatibility, contact us before ordering and we will point you to the right product.
Can I get a full spool or bulk pricing?
Yes. For reels, high quantities, or recurring orders, request a quote and we will come back with pricing and lead time, usually the same business day.
