Thermocouple Wire

VacTyte™ F8 is a high performance thermocouple wire. This wire is a reusable, leak proof lead-through for vacuum bag sealant tape penetrations. Resistance to kinking and knotting contributes to reusability.

The unique feature of VacTyte™ F8 is that the wires are simultaneously encapsulated in a single ovoid PTFE extrusion with a narrowing between the conductors. This extrusion method eliminates possible leak paths within the insulation so wires need not be stripped for sealant penetrations. The wire is easy to seal between layers of sealant tape. VacTyte™ F8 can be stripped using conventional methods.

VacTyte™ F8 is certifiable to ASTM E207, ASTM E230 and EMF values are in accordance with ASNI MC96.1. Test reports are provided with each certification at no cost. VacTyte™ F8 wire may be ordered in custom lengths, or spools in Type J, 24 gage, 1/0.508mm iron and constantan conductors. Type K and other gages of wire are available on special order.
