  • Hardwall tubing adapters
  • Barbed softwall tubing adapters
  • Softwall adapter plugs for 1/4" AND 1/2" NPT ports

For secure fluid connections to a manifold, select a fitting based on your tubing outer diameter (OD) for hard wall tubing or inner diameter (ID) for soft wall tubing. Wrap NPT threads 3-4 times and wrench tighten for leak-resistant connections.
