Transparent silicone rubber tubing, 2 mm inner diameter by 3 mm outer diameter, 3.3 ft long, rated from −76 °F to 428 °F for fluid transfer and pump use
- Withstands -76 to +428F for extreme-temperature fluid transfer
- Soft 65-degree silicone bends easily without kinking in tight routing
- Transparent 2mm bore allows instant visual inspection of fluid flow
- 5mm wall resists UV, ozone, gases and moisture for long service life
- 3ft length suits peristaltic pumps, siphoning, aquaponics and water or oil changes
Silicone Tubing 2 mm ID 3 mm OD
This transparent silicone tube has a 2 mm inner diameter and 3 mm outer diameter with a 0.5 mm wall thickness. It comes in a 3.3 ft length and is made from soft, flexible silicone rubber rated at 65 Degree hardness. The material is non‑reactive and resists UV, ozone, gases and moisture. It is suited for pump transfer, siphoning, draining, water or oil changes and machinery connections.
Temperature Range and Flexibility Limits
The tubing withstands continuous temperatures from -76 to +428 °F without hardening or cracking. Its soft silicone construction stays pliable in cold conditions and does not become brittle at the upper limit. The 0.5 mm wall keeps the hose flexible enough for tight bends in peristaltic pumps, but it cannot hold pressure like reinforced hose. Electrical casing use is limited to low‑voltage insulation because the thin wall offers no mechanical protection.
Replaces Stiff PVC or Nylon Hose
This tubing replaces rigid PVC or nylon lines that kink, yellow or crack after repeated heat cycles. The jump is worth it when you need visual fluid inspection, a wide temperature span or a hose that stays supple in sub‑zero or near‑boiling conditions. It is not for high‑pressure hydraulic circuits, fuel lines requiring specific chemical ratings or installations that need a thicker wall for abrasion resistance.

Questions about this item
Should I choose the 2mm ID × 3mm OD size or a different diameter for my pump?
The tubing supplied is 2mm inside diameter by 3mm outside diameter with a 0.5mm wall; choose this size when your pump barbs or fittings match those dimensions.
What does the –76 °F to +428 °F temperature range mean once the tube is installed in my machine?
The silicone rubber stays flexible and non‑reactive from –76 °F up to +428 °F, so it will not stiffen in freezing conditions or degrade when conveying hot fluids.
How does the 65‑degree hardness affect what fluids I can push through the hose?
At 65 Shore A the tube is much softer than PVC or nylon, giving excellent grip on barbs and good resistance to UV, ozone, gases and moisture for water, oil or air transfer.
