Product Description


  • The ball check in the head of the fitting prevents dirt and grit from getting into the bearing
  • The fittings can be wiped clean without forcing foreign material into the fitting and the bearing
  • The fittings have a specially formed lip at the fitting base that locks the spring and ball securely in place
  • The internal spring on the fittings is tempered with music wire, coiled so that it cannot be compressed to restrict the flow of heavy lubricants, or forced out of the body under normal pressures
