 Parker Quick Couplings
 High Pressure Stainless, Non-Spill Quick Couplings, Sizes to 2 inch, (hydraulic) up to 10,000 psi - Snap-tite 71 Series Couplers
  Parker's high pressure stainless steel, non-spill quick couplers and nipples are available in a wide range of sizes for use in hydraulic applications where fluid lines require fast and easy connection and disconnection with minimal spillage.    
    Snap-tite 71 Series Couplers (hydraulic) up to 10,000 psi connect with Snap-tite 71 Series Nipples. These are double shut-off, non-spill, push to connect quick couplings for high pressure applications. Couplers and nipples are available in a wide range of sizes up to 2 inch with material options including steel, 316 stainless steel, or high pressure stainless steel.
 
 Note: The 71-3 style couplers and nipples are interchangeable with the previous Snap-tite design couplers and nipples in sizes 3/8", 1/2", and 3/4". Old style 1" couplers and nipples (71-2C16 and 71-2N16) are not interchangeable with the 71-3 design.
