Silicone tubing for pump and transfer jobs

This clear silicone tube has a 1 mm inner diameter and 4 mm outer diameter, giving a 1.5 mm wall thickness. The 16.4 ft roll is suited to fluid-handling tasks such as water or oil changes, siphoning, draining and machinery connections. It is made from non-reactive silicone rubber that stays flexible across a wide temperature range.

Temperature range defines the practical envelope

The material withstands continuous exposure from -76 °F to +428 °F, so it remains pliable in freezing conditions and does not degrade near hot engine components or electrical casings. Hardness is rated at 65 Shore A, which keeps the tube soft enough for tight bends while resisting collapse under vacuum. These limits set the boundary for any pump or transfer design.

Build quality and daily handling

The uniform 1.5 mm wall gives consistent strength without adding bulk, and the clear finish lets operators confirm flow visually. Silicone's natural flexibility means the tubing routes around obstacles without kinking and seals onto barbed fittings without extra clamps in low-pressure use. The 5 m length can be cut to exact runs, reducing waste and potential leak points in automotive, industrial or electrical sleeving jobs.

Questions about this item

How do I know if the 1 mm inner diameter will fit my pump fittings?

Measure the barbed fitting on your pump; the tubing’s 1 mm bore matches fittings sized for 1 mm hose, while the 4 mm outer diameter and 1.5 mm wall give a secure grip.

Will the tubing stay flexible at the rated -76 °F to +428 °F range?

The silicone rubber keeps its softness across the full -76 °F to +428 °F span, so it will not stiffen in freezing conditions or soften excessively near boiling water.

Does the 65-degree hardness rating affect how tightly it seals on barbs?

At 65 Shore A the tube is firm enough to hold its shape on 1 mm barbs yet pliable enough to seat without clamps in most low-pressure transfer jobs.
