Graphite Packing Wire Description
Graphite Packing Wire conforms to the shape of the material, resulting in increased strength and durability. It is suitable for use with all types of graphite, copper, aluminum, brass, stainless steel, and other metals including copper and plastics. Excellent corrosion resistance, high-temperature tolerance, diameter, weight and strength, low-temperature resistance to ensure smooth operation and longer life, and maximum performance. Ideal for a wide range of operating temperatures and easy installation and a long life span of weather conditions.

FAQs
Q1: What is Graphite Packing Wire made of?
Graphite Packing Wire is typically made from high-purity graphite fibers or yarns, often reinforced with metal wires (such as stainless steel, inconel, or nickel) for added strength and durability.
Q2: What is the primary purpose of Graphite Packing Wire?
It is used as a sealing material in industrial applications to prevent leakage in pumps, valves, and other machinery under high temperatures, pressures, or chemical exposure.
Q3: What are the temperature limits for Graphite Packing Wire?
Depending on the specific grade and reinforcement, it can withstand temperatures up to 650°C (1202°F) in oxidizing environments and even higher (up to 3000°C or 5432°F) in inert or non-oxidizing environments.
