MALE TIP STANDARDIZATION
8010 Series male tips meet ASAE #S366, SAE # J1036, and I.S.O. #5675 standard requirements.
These engineering societies have established the following specifications for agricultural male tips:
  • Physical Dimensions. Critical dimensions are to be specified :
    • 1) from the nose of the tip to the locking ball groove,
    • 2) from the locking ball groove to the shoulder where the hex begins,
    • 3) diameter of the nose portion, and
    • 4) valve location in both open and closed position.
  • Valve Spring Force. The force required to push the valve to the flush position is not to exceed 10 lbs.
  • Maximum Pressure Drop. The pressure drop at a flow of 16 GPM is not to exceed 25 PSI.
  • Rated Working and Burst Pressure. The rated working pressure must be a minimum of 3000 PSI. The burst pressure must be a minimum of 10,800 PSI.

All standards are established around male tips.

Female bodies should be designed to accept an industry standard male tip. All Pioneer female bodies having ½" body size designed for agricultural use will accept such a standard male tip.
