Threaded Protection Plugs, made using red low-density polyethylene, are plastic plugs that help to provide protection with threaded fasteners.
They provide excellent protection against dirt, moisture and corrosion.
Often found in hydraulic, pneumatic and more generalised engineering industries, the plug has an easy to grip head for convenient installation, and is threaded to ensure a secure fit.
Available in a range of sizes with specials available to order – and in UNF and Metric.
