  SP Coupler Type A, Steel, NBR Socket, Female Thread

  NITTOKOHKI

  [Features]
  · "SP coupler" high flow rate type
  · Higher flow rate: Flow rate is higher by 7 to 64% compared to the conventional "SP coupler."
  · Center automatic return PAT of valve: Shape of the coupler built-in valve has undergone renewal.
  · After separation, the valve is automatically reset to ensure stable sealing in the unit state (1 to 8SP-A types).
  · Smooth connection: More comfortable connecting operation with socket due to smooth shape on plug tip.
  · Compatibility: Supports existing SP couplers as well, use as needed.
  ▪ Flow rate property: Even if the main body material is different, the flow rate characteristics are the same.
  · The main body material can be chosen according to usage.
  · Snap-stopper (sold separately): Allows you to prevent inadvertent withdrawal after connection, improving mounting performance of the simple stopper.
  · A new main body shape enables secure lock.
  · Green procurement compliant product: Nickel plating is used in surface treatment of the steel body.
  ▪ We strive to reduce the environmental load.
