SumiMark® Tubing
Cost Effective - Consistent - Quality
Product Overview:
SumiMark® tubing is available in a wide range of types including general purpose polyolefins, dual wall tubings, high temperature PVDF and flouroelastomers. SumiMark® tubing is made to the highest quality standards in the industry. In addition to providing strain relief and insulation, it provides an excellent surface on which to mark.
SumiMark® tubing is supplied on continuous spools, allowing you to create the exact length of marker needed, with no waste, resulting in tremendous cost savings. Diameters of 1/16" to 2" with shrink ratios of 2:1, 3:1 and 4:1 are available. There is minimal longitudinal change after shrinking, so marks will not become distorted when installed.

SumiMark® tubing is available in black, white and colors and meet the respective military and commercial specifications (AMSDTL23053, UL, VW1, CSA).
