Junkosha’s Brass Fittings include box nut tightening torque-type fittings.
We have two lines: a metric series and an imperial series.
Both series meet the JIS B8381-1995 Pneumatic Fittings standard and can be used for automation, labor-saving equipment, and industrial robotics.
We also have a lineup of RoHS-compliant products.

Features
- Our metric series and Brass Fittings (excluding handy-touch fittings and instant couplings) meet Japanese Industrial Standard B8381 for pneumatic fittings.
- Holding the tube insert and tightening with the sleeve/box nut ensures a secure connection (excludes handy-touch fittings and instant couplings).
- Handy-touch fittings and instant couplings are compact and ideal for saving piping space. They are also nickel plated to boost resistance against rust and prolong the lifespan.
