Bulkhead Barb Fittings


Pneumadyne’s Bulkhead fittings are available with barb sizes ranging from 1/16 to ¼ Tube Id.  Our consistently sharp, single-barb design provides a tighter grip and seal than standard multiple barbs, ensuring permanent polyurethane tubing connection without the need for clamps in most applications.  A smoother approach angle also eases tubing installation.

  • External thread size:  10-32 (M), ¼-28 (M), 5/16-24 (M),  1/8 NPT and 3/8-24 (M)
