To provide a pneumatic piping connector unit which connects a plurality of hoses to each other and prevents foreign matters from mixing into the air flowing through the hoses.
A plurality of fitting holes 21 are formed in a first connection board 11 and primary-side joint pipes 23 are detachably installed in the fitting holes 21. A plurality of fitting holes 22 are formed in a second connection board 12 which abuts against the first connection board 11 so as to be fastened thereto, and secondary-side joint pipes 24 are detachably installed in the fitting holes 22. The joint pipes 23, 24 are formed of resin and include flow paths 23a, 24a therein, respectively. A primary-side hose 13 is detachably attached to a hose-side end 23c of each joint pipe 23. A secondary-side hose 14 is detachably attached to a hose-side end 24c of each joint pipe 24. The air flowing from the primary-side hose 13 to the secondary-side hose 14 is not exposed to a metallic face. A space between the primary-side joint pipe 23 and the secondary-side joint pipe 24 is sealed by an end face seal member 38.
