Overview
The Garlock 47390-7372 is a premium graphite braided packing engineered for static and dynamic sealing applications across industrial equipment. This compression packing style combines graphite fiber reinforcement with braided construction to deliver high tensile strength, low friction, and excellent heat dissipation. Each box contains 2 units of the 490-Z/98-Z configuration, making it ideal for maintenance replacement in pump and valve stuffing boxes.
Key Features
- Graphite fiber-reinforced braided construction for superior tensile strength and durability
