Sumitomo Electric Interconnect Products, Inc. (SEIP) is an ISO 9001:2008 registered manufacturing facility in San Marcos, California, where products based upon heat-shrinkable plastics technology are engineered, manufactured, and sold. A variety of customers in industries such as automotive, aerospace, appliance, communications, electronics, medical, and transit vehicles have come to rely upon the excellence of SEIP quality and service. SEIP products are conveniently inventoried and sold via Peerless Electronics.

Sumitube® products conform to a wide range of industry standards including military, aerospace, UL and CSA. In addition, many specialty type materials are offered such as high-temperature, low smoke, medical, conductive, chemical resistant, and low outgassing grades. Materials available include irradiated cross-linked heat-shrinkable polyolefins, fluoroplastics, and elastomers in diameters ranging from 3/64" to 4", in colors.

With the controlled application of heat, the diameter of a Sumitube® product will be reduced to a pre-determined size, thus providing an excellent conformal and protective insulating layer over many types of substrates. Expanded vs. recovered diameters may have shrink ratios that vary from 1.3-to-1 up to 6.0-to-1.

In addition to the standard sizes, colors, shrink ratios, and packaging shown in the accompanying data sheets, Sumitomo Electric Interconnect Products, Inc. will be delighted to customize products that better accommodate the end-user needs.

Please refer to the handy heat shrink tubing selector below. Remember-if we don’t have it we can order it for you!
