  Parker Quick Couplings 
  Rigid Mount, Connect Under Pressure, 1/2” Pioneer Agricultural Quick Couplings, ISO 5675, 3000 psi, - 8450 Series Couplers 
           Pioneer rigid mount, connect under pressure quick couplers are used across a spectrum of agricultural hydraulic applications where fluid lines require fast and easy connection while either or both the coupler and nipple are under pressure.  
            
            
            
           Pioneer 8450 Series agricultural Couplers (hydraulic) 3000 psi, will connect under pressure with 8010 Series Nipples (ISO 5675 Pioneer universal male tips) while either or both the coupler and nipple are under system pressure.  
               
  8450 Series push to connect couplings have poppet valves and a push-pull sleeve design to act as a breakaway when rigidly mounted or held in a 5006-4 clamp. Coupler port ends are 7/8 - 14 ORB threads, male or female, to allow direct mounting to a control valve or rigid tubing.
