Polyethylene Plugs

Threaded plugs made from low-density polyethylene are for flared JIC fittings.

The plugs protect internal threads or provide a positive seal for lowpressurerequirements, such as blocking holes in painting masks and shipping containers, and feature a knurled exterior that makes them easy to apply and remove.
