The Rain Bird TSJ100PRS turf swing joint is a preassembled 1 in x 12 in swing joint with an integrated pressure regulating system (PRS) preset to 70 psi for the 1 in model. Built for rotors with 1 in inlets, it maintains a constant outlet pressure at the rotor, improving spray uniformity and reducing misting in high or fluctuating supply conditions.

  • Integrated 70 psi PRS: Preset regulation at the rotor inlet for consistent nozzle performance and reduced water waste.
  • Durable construction: Swept-elbow design with high pressure rating (315 psi) and smooth flow path to minimize pressure loss.
  • 1 in M NPT inlet/outlet, 12 in length: Fits standard 1 in rotors and provides 12 in reach (30.5 cm) to grade.
  • Leak protection: Double O-ring and visible thread stops keep threads clean and allow hand-tight installation.
  • Easy installation: Preassembled unit with oversized threaded inlets and clear stops for faster, secure hookup.
  • Performance: Maximum flow approximately 22 GPM; not recommended where lateral pressure is equal to or below the nominal regulation.

Designed for turf rotors in commercial and residential irrigation, the TSJ100PRS gives designers greater control over zone pressure and droplet size. For reliable results follow Rain Bird installation guidance: avoid supply line velocities above 5 ft/sec and do not open the PRS unit—there are no user-serviceable parts. Technical specification sheet is available for designers and contractors.

Frequently Asked Questions

What pressure does the TSJ100PRS regulate to at the rotor inlet?
The TSJ100PRS (1 in model) is preset to regulate outlet pressure to approximately 70 psi for consistent nozzle performance.
Can I service or open the PRS unit myself?
No. The PRS contains an internal spring and has no user-serviceable parts; do not open the unit.
What inlet and outlet thread sizes does it use?
The TSJ100PRS uses 1 in M NPT inlet and outlet connections and a 12 in length to position rotors at grade.
Are there flow or installation limits I should follow?
Maximum flow is about 22 GPM. Avoid supply line velocities over 5 ft/sec and don’t use where lateral pressure is at or below the nominal regulation.
