5/8" x 18 UNF Threaded Sealing Plug | Yellow HDPE
Frequently specified for UNF thread protection, this yellow HDPE plug helps reduce dirt ingress and thread damage in demanding service environments. The wording and fit make it suitable where teams need a HDPE UNF plug rather than a permanent metal plug.
Used on fine-thread fittings, this yellow HDPE plug supports clean handling of automotive, hydraulic and precision-engineered assemblies. This version combines a 20.9mm length with a 22.0mm head size, giving a clear size reference for matching against the threaded port.
Common Applications
- Protecting machined threads in engineering workshops
- Closing open ports on pneumatic assemblies
- Preventing dirt ingress during transport
- Preparing components for inspection or packing
