Unique-Bargains Silicone Hose 3mm ID x 7mm OD 5ft Clear

SKU CH-03B3-R5PTY

Clear silicone tubing moves liquid or gas at temperatures from -60 °C to 200 °C and comes in a 1.5 m length

  • Withstands -60 °C to 200 °C for extreme environments
  • 5 m length gives ample reach for routing
  • 2 mm wall thickness adds burst resistance
  • Flexible silicone rubber bends without kinking
  • Suitable for liquid and gas transfer in pumps and aquariums

Clear Silicone Tubing for Fluid Transfer

This clear silicone tube measures 3mm inner diameter by 7mm outer diameter with a 2mm wall thickness. Supplied in a 1.5m length, it handles temperatures from -60 °C to 200 °C. The material stays flexible and durable for shaping around fittings. It suits liquid and gas transfer in pumps, drains and aquarium lines.

Replaces Stiff or Heat-Sensitive Hose

Swap out rigid plastic or rubber lines that kink, crack or soften near hot components. The silicone construction tolerates -76 °F to 392 °F without losing elasticity. The jump is worth it when routing through tight bends or when the fluid path sees wide temperature swings. The 5ft roll lets you cut exact lengths for a cleaner install.

Suits Hobbyists and Light-Duty Plumbing

Aquarium keepers, PC liquid-cooling builders and small-pump operators gain a transparent, high-temp line that is easy to inspect. Buyers needing larger bore sizes, reinforced pressure ratings or food-grade certifications should look elsewhere. The single 5ft piece also limits very long continuous runs.

Questions about this item

What inner and outer diameters does the 3 mm ID × 7 mm OD silicone hose need to fit over or into?

The hose has a 3 mm inner diameter and a 7 mm outer diameter, giving a 2 mm wall thickness, so it fits 3 mm barbs or 7 mm push-fit fittings.

How is the 1.5 m clear silicone tubing installed, and what step do users often miss?

Cut the 5 ft length to size, slide it over the barbed fitting, and secure with a hose clamp; the step often missed is warming the tubing in hot water first so it stretches over the barb without kinking.

When will the silicone hose need replacement in a pump or aquarium line?

Replace it if the tube hardens, cracks, or turns cloudy after prolonged exposure near the 200 °C upper limit or after repeated freeze-thaw cycles down to -60 °C.
