DR-25-3/16-0 Tubing, Heat-Shrinkable, Thermofit DR-25 3/16″, Shrink Ratio 2:1, Elastomeric, Fluid & Abrasion Resistant — BOLTON SKU 59189.
About the DR-25-3/16-0 Heat Shrink Tubing
DR-25-3/16-0 is a size from the TE Connectivity (Raychem) Thermofit DR-25 family, a heat-shrinkable elastomeric tubing developed as a jacketing material for demanding cable harnesses. Unlike ordinary polyolefin sleeving, DR-25 is a flexible, rubber-like crosslinked elastomer engineered for long-term heat resistance and optimum high-temperature fluid resistance, with good abrasion performance. This 3/16 inch size is supplied at approximately 4.8 mm inside diameter and recovers to around 2.4 mm, a 2:1 shrink ratio; the -0 suffix denotes black. Distributor and manufacturer data quote an operating temperature range of −75 °C to +150 °C, with installation (recovery) at about 175 °C, and reference MIL-DTL-23053/16 for this tubing type. It is widely specified for military vehicle and airframe harness jacketing as well as motorsport looms.
