Safety & Electrostatic Dissipation Features
- Electrical Resistance:
- 2.5 Ohms/m for hose sizes < 2″.
- 1.0 Ohms/m for hose sizes > 2″.
- Electrical continuity can be maintained by baring the inner wire near the fitting to allow positive connection of the wire to the fitting.
- This process may introduce a potential corrosion path to the inner wire, so care needs to be taken.
- Minimum Burst Pressure: 4 times Working Pressure (Safety Factor 4:1).
