Sumitomo Tubing

Authorized Distributor for Sumitomo Electric Interconnect Products

Allied Wire & Cable is an authorized distributor of Sumitomo’s Sumitube® Heat Shrink Tubing. Manufactured in a wide range of materials, sizes, colors and shrink ratios, Sumitomo’s Sumitube® heat-shrink products meet AMS-DTL-23053 (formerly M23053 Mil-spec standard) or UL/CSA standards, and also are available in commercial grade versions. Sumitube® products are available in varying flexibility, from very flexible to semi-rigid.

Each type of heat shrinkable tubing has an excellent operating temperature range, allowing for a wide variety of possible applications. Ranging from -40°C to 200°C, Type FE3 has the widest temperature range but the majority of Sumitube® products have an also exceptional range of -55°C to 125°C, allowing for even colder temperatures without degradation.

In addition to temperature ranges, Sumitube heat shrink is also available in a wide range of sizes. Starting as low as 3/64” Sumitomo’s shrinkable tubing is available in ranges from 3/64” or 1/8” to 2” or even as high as 4”.
