PG 21 Liquid Tight Threaded Plug | Black Nylon
Offering a clean finish for threaded apertures, this PG 21 plug combines a black Nylon body with practical hex-head installation. This makes it a practical hex head threaded plug for UK industrial sealing work.
The hexagonal head gives engineers a positive wrenching surface for controlled installation, while the screwdriver slot helps with adjustment in tighter panel areas. The black finish is often preferred for darker housings, machinery frames and discreet enclosure builds.
Common Applications
- Production line equipment upgrades
