Sumitomo Sumitube B2(3X) 12/4mm Flexible Polyolefin 3:1 Heat Shrink Tubing - Black (By the Foot)

Black Sumitomo Sumitube B2(3X) 12/4mm 3:1 heat shrink tubing

Sumitomo Sumitube B2(3X) in black is flexible, flame-retarded polyolefin heat shrink tubing with a 3:1 shrink ratio for wire identification, insulation and protection of suitable terminations and light wire harness assemblies. This 12/4mm size has a 3:1 shrink ratio and is sold by the foot in a continuous length.

The 3:1 recovery ratio gives you extra clearance to pass over larger components before shrinking onto a narrower section. It recovers to approximately one-third of its expanded diameter, rather than the one-half diameter of standard 2:1 tubing.

Ordering and choosing your size

Quantity 1 is 1 foot; quantity 10 is one continuous 10-foot length. Cut sections to suit your assembly. Choose tubing that passes over the largest component before heating and recovers sufficiently around the section you need to cover. The shrink ratio refers to diameter, not length. Confirm expanded and recovered inside-diameter limits when fit is critical.

Applications

• Color identification and bundling of electric wires.
• Insulation, protection and reinforcement of suitable wire joints and terminations.
• Protection of suitable resistors, capacitors and light harness components.
