Instant Fittings

JUNRON® Instant Fittings M series The compact, simple structure significantly reduces the time required for pipe construction.
These highly reliable fittings can be used for both JUNRON A and JUNRON U tubes. Two series are available: M series (small) and W series (sputter-resistant). These instant fittings ensure faster pipe construction than standard fittings.


  • Electro-less nickel plating is standard equipment for metal parts.
  • Screw size can be distinguished at a glance by different color seals applied.
  • Positioning of the body is possible based on the direction of the tubing.
  • The tube grip rotates smoothly in the fitting to prevent tube damage caused by tube rotation.
