Why Use the Nelson® Port Stud Over the Others?

  • Competitive offerings are still 2 components, brazed together, creating a potential leak point
  • Manufacturers are increasing operating pressures, putting the brazed joint more at risk
  • OEM's can eliminate hydraulic pressure testing in the assembly area with a 1-piece port stud - saving time & money!
  • The part is labor intensive resulting in a higher cost
