Item Features
  • Lever control operates by cam principle and provides variable flow from trickle to full force, variable flow with no lock that rusts in place.
  • Draw straps are made of 1040 hot rolled steel which is much harder (Brinell 175/200) and stronger, greatly reduces wear of straps and eliminates side pull on operating rod, longest operating life.
  • Stainless steel operating rod is ground and polished and will not cut out packing and packing nut, like brass rod used by other companies, best material for longest operating life.
  • Heavy duty hose adapter threaded for standard 3/4 in hose coupling.
  • Extra thick walled head casting greatly reduces breakage and insures longer life, time-proven heavy-duty design takes years of abuse.
  • Pivot connector with two nuts provides simple positive adjustment and eliminates unreliable set screws, adjustable for years, not like rusted in set screws.
  • No exposed threads on galvanized rod and threads on galvanized pipe are coated with bitumastic to prevent rusting and prolong life of hydrant, no exposed steel to rust.
  • Extra thick walled valve body to insure longer life and trouble free service, time-proven heavy-duty design.
  • Patented plunger arrangement ensures even flow from trickle to full force, closes drain at any flow rate and opens drain in off position to prevent freezing, longest operating life available in the industry by over 200%.
  • Krayton G cup seals provides a much longer life than leather, close tolerance uniformity, unaffected by chemicals and passed a 1 million cycle test, longest operating seals in the industry.
  • 3/8L beveled bibb washer made of SBR compound with 90 durometer hardness, assures positive shut-off and longer life than soft one piece plunger, longer operating life than all competitors.
  • Stainless steel spring takes up slack of normal wear and eliminates numerous adjustments of hydrant head linkage, automatically adjusts for years of service.
  • Swivel parts permit withdrawal of moving parts without digging up hydrant, nothing in head assembly to disconnect or adjust when removing, simply unscrew entire head assembly from galvanized pipe and pull up valve stem with plunger for inspection.
  • If parts dont swivel, they could be unscrewed from rod when taking off head above ground.
  • 3/4 in hose thread adapter stainless steel operating rod thru Teflon packing automatic self-adjusting plunger.
  • Automatic self-adjusting plunger.
  • 1 in galvanized stand pipe.
