Product questions
Before you choose.
Do all PTFE, FEP and PFA wires have the same rating?
No. The displayed −60°C to +200°C is the confirmed standard wire range. Other constructions must be selected using their own model specification; the material name alone is not a rating.
What should I provide to match an existing wire?
Use the wire marking or drawing, conductor size, insulation material, voltage and temperature. Add a stripped-end photo and finished diameter if available.
Samples & repeat orders
Keep the specification with the order.
Define the cable
Prepare the model or drawing, operating conditions, quantity and destination. Include required documents and your requested delivery date.
Prepare a new requirement ↗Define what to check
Include the trial length and the dimensions or performance you need to evaluate. Sample availability, cost and timing are confirmed separately.
Prepare a sample request ↗Reference the approved version
Use the previous order, drawing revision or approved sample reference. State what stays the same and any changes in size, material, colour or packing.
Prepare a repeat-order request ↗Your application
Prepare a clear requirement.
