High-Speed Chemical-Resistant Packing Seals

Built for high-speed pump and valve applications, these super-tough seals are made of expanded-graphite yarn with carbon-yarn corners. Use them with acids, alkalies, brines, and solvents. Cut these seals to size with a knife; then pack them into place.

High-Strength Expandable Wire Sleeving

With excellent torsional strength, this sleeving withstands the extreme twisting found in robotics. Made of carbon fiber, it has impact strength similar to steel yet is lighter than plastic and rubber. Resistant to corrosion and chemicals, it’s often used to protect brake lines and hydraulic lines. It’s expandable, so it stretches to fit over items for easy installation, then tightens around its contents for a secure fit. The braided construction permits heat and moisture to dissipate. Cut with scissors or a hot-blade knife.
