Zinc Plated Steel Square Head Solid Plugs are designed to close female-threaded openings, providing a secure seal for system termination, testing, or maintenance access. The square head allows for easy installation and removal using standard tools, even in tighter spaces, while the solid construction offers added strength and durability. Manufactured to ASME B16.14 standards with NPTF threads, these plugs provide a leak-resistant connection. Zinc plating delivers corrosion resistance for reliable performance across a range of environments, and materials are RoHS compliant. Each fitting ...

Maximum heat resistance of nylon plastic: 194° F (90° C). Comes complete with unassembled oil-resistant synthetic rubber gaskets.

GN 738 magnetic plugs attract iron particles which might be suspended in the liquid. The magnetic pin is of a length which makes it impossible to demagnetize itself. To avoid breakage or de-magnetizing, round rod magnets are fitted with a plastic protection tube. This tube has to be removed prior to installing the plug.The seal is retained in a radial undercut in the mating face, which prevents it from dropping out and from extruding when the plug is tightened. For this reason the seal can be of a softer material which offers better sealing. NBR seal: maximum heat resistance: 120°C ...

GN 742 fill/drain plugs are fitted with outside diameter d1 to fit screw holes with BSP threads included in DIN 3852. The seal is retained in a groove undercut in the mating face, which prevents it from dropping out and from extruding when the plug is tightened. For this reason the seal can be of a softer material which offers better sealing. Maximum heat resistance: 180°C (356°F). 2mm Vent Hole and M5 x .8 Dipstick Thread
