    Connect male- and female-threaded parts of different thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through. Attach your parts to these adapters and use a hex key to secure the connection. Made of 304 stainless steel, all will hold up in wet environments. O-rings on each side create a tight seal, making them good for vacuum and compressed-air applications.
