Beswick Engineering Barbed Fitting

 

Barb fittings are best suited for use with soft flexible tubing such as Polyurethane or Vinyl at low pressure. All of the barb fittings within this catalog feature a proprietary single-edge “line contact” barb profile. This design allows the tubing to be pushed onto the fitting by hand and also ensures a leak-tight connection along the inner diameter of the tubing. These fittings can generally handle pressures from full vacuum up to 80-100 psig without a clamp, depending on tubing and application conditions. With a clamp installed, the tubing burst pressure typically becomes the limiting factor.
