NPT 1/4 Liquid Tight Threaded Plug | Black Nylon
NPT 1/4 black liquid tight threaded plug is made for sealing unused threaded entries where water, oil or dust could affect equipment performance. This makes it a practical NPT 1/4 liquid tight threaded plug for UK industrial sealing work.
The Nylon construction is electrically non-conductive and corrosion resistant, making it a useful alternative to metal plugs in cabinets, machine housings and washdown environments. The black finish is often preferred for darker housings, machinery frames and discreet enclosure builds.
Common Applications
- Sealing unused threaded entries in electrical enclosures
- Sealing NPT threaded ports on hydraulic and pneumatic equipment
- Closing threaded conduit openings during panel builds
- Protecting equipment from water, oil and dust ingress
