Hose Barb Termination
Barbed fitting terminations hold on the Inside Diameter (ID) of a tube. They are typically used with PVC, polyurethane, silicone and other rubber and plastic tubing. These types of connectors are designed for one-time installation, but if the tubing is flexible enough they can be removed. They are sized for tubing with inner diameters (ID) from 1/16″ to 3/4″ and 3mm to 19mm. The 1/16″ and some 1/8” barbs have a shroud to provide extra strength.
NOTE: Hose barbs are available in both single barb and multiple barb styles. Single barb designs work well with soft flexible tubing, whereas multiple barb designs function well over a wider range of tubing durometers. Hose barb retention depends on the OD of the barb itself and the sharpness of the barb. Regardless of the barb style, look for well-molded, sharp barbs and consider not only the pull-off force, but also the installation force required to install the tubing.
Pipe Thread Termination
Pipe thread connectors are industry standard, threaded connections that use a tapered male into a tapered female thread and tighten on themselves to seal with the added help of pipe dope or Teflon® sealants. These connectors offer equipment manufacturers the flexibility of a threaded port that will accept many different connections as long as they are standard pipe thread connections. The most common types of pipe threads are NPT and BSPT but others are available.
NOTE: It is important to use appropriate gauging and tightening techniques for molded pipe threads to avoid permanent deformation and/or stripping of the plastic thread of the coupling. CPC recommends tightening plastic threads to hand tight plus 1-2 turns. Adjust for your application as necessary.
