The Additel 100 series Hose Test Kits are designed to extend your pressure calibrations to a convenient location and to adapt from one press connection to another. Each Tesk kit has 5 feet of flexible hose rated to 8,000 psi (550 bar) or 15,000 psi (1,000 bar) which connects a male NPT, BSP, or Metric connector to a variety of female quick connectors. Additel's specially designed quick connectors allow for hand-tight connection without the need for wrenches or Telflon tape. The Additel 100 series Hose Test Kits are a great accessory to any pressure pump or controller.
