2-Pack M18X1.5 Stainless Steel Bung Plugs - Hex Head Pipe Fittings For Water Ports

These might look simple, but they're super useful if you work with plumbing or automotive systems. You get two stainless steel 304 bung plugs with M18X1.5 male threads and hex heads that make installation easy with a standard wrench. The stainless steel construction means they won't rust or corrode, so they're perfect for blocking off water ports, water pump connections, or temperature tank openings. The hex head design gives you good grip and torque when tightening them down. Since they're solid (not hollow), they provide a complete seal that won't leak. Whether you're capping off unused ports during a repair or need permanent plugs for your system, these heavy-duty plugs get the job done. The package comes with two plugs, which is handy because you always seem to need an extra one somewhere!
