Unique-Bargains Silicone Tubing 1mm ID 4mm OD 2m Clear

SKU CH-DC34-3A5JS

Clear silicone tubing with 1 mm inner and 4 mm outer diameter, 2 m length, handles -76 °F to 428 °F at 65 hardness

  • Clear tubing lets you see flow inside
  • Withstands -76 °F to +428 °F for extreme environments
  • 65 Shore A hardness keeps it soft yet kink-resistant
  • 5 mm wall thickness handles pressure without collapsing
  • 2 m length supplies enough hose for pump and transfer jobs

Clear Silicone Tubing for Fluid Transfer

This 2 m length of clear silicone tubing has a 1 mm inner diameter and a 4 mm outer diameter with a 1.5 mm wall thickness. It is made from non-reactive, flexible silicone rubber designed for pump and transfer applications. The material withstands temperatures from -76 °F to +428 °F and carries a 65-degree hardness rating.

Suited for Small-Bore Fluid Lines.

The tubing fits machinery connections, electrical casings, siphoning, draining and water or oil change tasks where a 1 mm bore is required. Builders who need a larger inner diameter for higher flow rates or a different wall thickness should look at something else. Buyers requiring coloured or reinforced hose will not find those options here.

Verify Bore Size, Temperature Range

Confirm that the 1 mm inner diameter and 4 mm outer diameter match the fittings on your pump or equipment. Ensure the operating range of -76 °F to +428 °F covers the fluids you intend to transfer. Check that the 6.56 ft total length is sufficient for your routing needs.

Questions about this item

What pump or fitting size matches the 1 mm inner diameter of this tubing?

The tubing has a 1 mm inner diameter and 4 mm outer diameter, so barbed fittings or pump nozzles sized for 1 mm ID will seat correctly.

Will the tubing stay flexible if I route it near components that reach 428 °F?

Yes, the silicone rubber is rated from -76 °F to +428 °F with a 65 hardness rating, so it remains soft and flexible at that temperature.

How can I confirm the wall thickness is the specified 1.5 mm after cutting a length?

Measure the wall with a caliper; it should read 1.5 mm (0.06 in), which equals half the difference between the 4 mm OD and 1 mm ID.
