Applications

  • Ideal for use when tightening steel tubing for hydraulic tubing and pneumatic applications.
  • Note: Flare nuts are typically not used on hydraulic hose connections. When tightening connections with hydraulic hose, special care must be taken or you dramatically shorten the service life of that hose. See the section on tightening hydraulic connections for more information.
