Bulkhead Union


Bulkhead Unions are a fast and easy method of connecting components in a pneumatic system.  Recommended for use with 95A Polyurethane tubing, these fittings accommodate tube sizes ranging from 1/8” OD to ½” OD.  The oval design of the release button provides a larger surface area making tubing disconnection easier than standard round-style collets.

  • Recommended for use with 95A polyurethane tubing
  • Durable nickel plated brass construction
  • Push-in fittings enable quick tubing connection and disconnection
  • Suitable for vacuum applications to 29.5” Hg
