How to find the right Barbed Press-In Plugs AI guide

What the AI looks for in Barbed Press-In Plugs

Sized to tubing ID
The plug's barb must match the tubing's inside diameter. An oversized plug splits tubing, and an undersized one blows out.
Permanent vs removable
Use a plug with a grip tab or flange if it must come out again. Use a fully inserted barb for permanent seals. Deep-barbed plugs are hard to remove without cutting tubing.
Pressure retention
Add a clamp over the plugged end on any pressurized line. A dead-end plug takes the full line pressure as blow-out force.
Material
Match the plug's chemical and temperature resistance to the line. The plug contacts the same fluid as the rest of the system.

Brands that matter

  • Nordson Medical (Value Plastics): Molded plastic barbed plugs and caps.

What to avoid

Questions

Plug or cap: which do I need?

A barbed plug goes inside the tubing. A cap fits over the end of a tube or a fitting.
