Unique-Bargains Silicone Tubing 2mm ID 3mm OD 3.3ft Transparent

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.
