SMC ZPT16UN-N01 | ZP Series Basic Flat Vacuum Pad 16mm Vertical Inlet With Adapter NBR Rubber 1/8 NPT Thread Connection

The SMC ZPT16UN-N01 is a basic flat type vacuum pad from the ZP series, configured with a 16mm pad diameter, vertical vacuum inlet, and threaded adapter for direct mounting. The "U" pad shape designates a flat type profile providing full-surface contact for reliable vacuum adhesion on smooth, flat workpieces. This straightforward configuration without buffer is ideal for fixed-mount applications where workpiece height is consistent and buffer compliance is unnecessary.

What connection type does the ZPT16UN-N01 use? The "N01" suffix specifies a 1/8 NPT (National Pipe Thread) connection, the most common thread standard for vacuum and pneumatic connections in North American industrial automation. This threaded interface provides a secure, leak-free connection that withstands vibration and repeated handling cycles without loosening, making it preferred over push-in fittings for permanent installations and high-reliability applications.

The "N" material code designates NBR (nitrile butadiene rubber) pad construction, the industry workhorse material for general-purpose vacuum handling with strong oil resistance and reliable sealing across 0°C to +70°C. The ZPT series suction cups are available in diameters from 2 to 125mm, six cup materials, and four cup designs including flat, flat with ribs, deep, and bellows types to suit a wide range of industrial applications.

This vacuum pad is RoHS compliant and integrates with SMC's full range of vacuum generators, in-line ejectors, pressure switches, and pneumatic controls. The basic flat pad with threaded adapter represents the most economical entry point for building vacuum gripping solutions in general automation, packaging, and material handling systems.
