Description

Silicone Rubber Vacuum Hose — Food-Grade Flexible Tube for Aquariums, Automotive & Air Lines

When standard PVC tubing cracks under heat or leaves an aftertaste in your aquarium, you need a material that holds up. This food-grade silicone rubber vacuum hose is built for hobbyists, mechanics, and DIYers who need a flexible, odor-free tube that won't degrade under temperature swings or prolonged fluid contact.

Each length is cut from solid-wall yellow silicone tubing with an inner diameter (ID) ranging from 2 mm (~0.08 in) to 14 mm (~0.55 in) and an outer diameter (AD) ranging from 4 mm (~0.16 in) to 18 mm (~0.71 in). Available lengths run from 1 M to 20 M, letting you order exactly what your project requires without waste.

Typical applications include freshwater and marine aquarium air lines, automotive coolant overflow and vacuum lines, food-processing equipment bypass hoses, and low-pressure pneumatic connections in workshop setups. The bright yellow color also makes routing easy to trace at a glance.

⚙️ Compatibility note: Select your Ø (ID × AD) size to confirm the tube fits your barb fittings, connectors, or nipples before ordering. Barb OD should match or be slightly larger than the tube ID for a secure seal.

✅ Key Features of These Silicone Rubber Vacuum Hoses

  • Food-grade silicone material — odorless, tasteless, and non-toxic; safe for aquarium livestock, drinking-water lines, and food-contact applications.
  • Wide temperature range — typically rated from −60 °C to +200 °C (−76 °F to +392 °F), handling engine bay heat and freezing outdoor runs without cracking or hardening.
  • Flexible and kink-resistant — the soft-durometer silicone wall bends around tight corners without collapsing the bore, maintaining consistent flow.
  • 18 ID × AD size combinations — from 2 mm × 4 mm up to 14 mm × 18 mm, covering most standard barb fittings used in plumbing, automotive, and aquarium hardware.
  • Cut-to-length options (1 M – 20 M) — order the exact run you need; longer coils reduce join points and potential leak paths in extended installations.
  • UV- and ozone-stable — silicone resists outdoor weathering better than EPDM or PVC, making it suitable for under-hood and exterior routing exposed to sunlight.

❓ Frequently Asked Questions

How do I choose the right ID × AD size for my fitting?

Measure the outer diameter (OD) of your barb or nipple fitting. The tube's inner diameter (ID) should match or be 0.5–1 mm smaller than the barb OD for a snug, leak-free push fit. For example, a 6 mm barb pairs well with the 6 mm × 8 mm or 6 mm × 9 mm tube variant.

Is this hose safe for use in a fish tank or aquarium?

Yes. The tubing is made from food-grade silicone, which is odorless, tasteless, and non-toxic. It will not leach plasticizers or chemicals into the water, making it suitable for freshwater and marine aquarium air lines and water return lines.

Can this silicone hose handle engine bay temperatures?

Silicone is typically rated to +200 °C (+392 °F), which covers most automotive coolant overflow, vacuum, and breather line applications. It also remains flexible at low temperatures (down to approximately −60 °C), unlike rubber hoses that stiffen in cold climates.

Will the hose kink if I bend it around a tight corner?

Soft-durometer silicone resists kinking better than rigid PVC or nylon tubing. For very tight bends (bend radius smaller than the tube OD), use a hose support spring or elbow fitting to maintain bore integrity and consistent flow.

Is the yellow color UV-stable for outdoor or under-hood use?

Silicone rubber has inherently good UV and ozone resistance compared to EPDM or standard PVC. The yellow pigment is blended into the silicone compound rather than surface-coated, so it will not peel or fade rapidly under normal outdoor exposure.

How do I cut the hose to the exact length I need?

A sharp utility knife or scissors cuts silicone cleanly. For a square, burr-free end, score around the circumference first, then cut through in one motion. Avoid serrated blades, which can leave a ragged edge that reduces seal quality at the fitting.

Can I use this hose for compressed air or pressurized lines?

This tubing is rated for low-pressure vacuum and air-line duty. For pressurized applications above approximately 0.3 MPa (about 43 psi), please contact us to confirm suitability, or consider a reinforced silicone hose with a braided inner layer.
