Description

Reliable Air-Tight Blanking for Pneumatic & Air Line Systems


These BSPP male brass blanking plugs are designed for quick and secure sealing of unused ports in pneumatic systems, manifolds, valves, and airline equipment.

Each plug is fitted with a rubber O-ring seal, ensuring a leak-free, air-tight connection without the need for PTFE tape — ideal for fast installation and maintenance.

Manufactured from nickel-plated brass, these plugs offer excellent resistance to corrosion, wear, and industrial environments.
