  • Clear tubing lets you see flow instantly
  • Withstands -76 °F to +428 °F for extreme environments
  • 65 Shore A hardness keeps shape under pressure
  • 5 mm wall gives kink-resistant flexibility
  • Suits water, oil, siphoning and electrical insulation

Product identity

Unique-Bargains clear silicone tubing with 1 mm inner diameter and 4 mm outer diameter supplied in a 1 m length. It suits hobbyists, maintenance technicians and small-scale fluid-transfer setups that need food-grade flexibility and wide temperature tolerance.

Deciding specification

The tube handles continuous exposure from -76 °F to +428 °F and carries a 65 Shore A hardness rating. That combination decides whether the material survives the intended fluid and thermal environment without hardening or cracking.

Capacity and limits

A 1.5 mm wall thickness gives enough burst margin for low-pressure pump, siphon and drain tasks while staying pliable for tight routing. The narrow 1 mm bore restricts flow volume, so high-throughput cooling or rapid oil-change jobs will need larger-bore hose.

Highlights

  • Clear tubing lets you see flow instantly
  • Withstands -76 °F to +428 °F for extreme environments
  • 65 Shore A hardness keeps shape under pressure
  • 5 mm wall gives kink-resistant flexibility
  • Suits water, oil, siphoning and electrical insulation

Questions about this item

How does the 1 mm inner diameter affect flow in a pump or transfer line?

The 1 mm bore restricts flow to very low volumes, making it suitable for metering, siphoning or small-diameter machine connections rather than high-volume transfer.

What does the -76 °F to +428 °F operating range mean for automotive or machinery use?

The silicone stays flexible in extreme cold and resists degradation near boiling coolant temperatures, so it can handle engine bay routing and hot fluid lines without cracking or softening.

Will the 4 mm outer diameter and 1.5 mm wall fit standard 4 mm push-fit fittings or barbs?

The 4 mm OD matches 4 mm push-fit collets, while the 1.5 mm wall gives enough rigidity to hold on barbs without kinking when clamped.
