Inch-to-NPT Male-Female Hex Thread Adapters with Through Hole
The through hole allows you to connect float rods to float valves.
Brass adapters have good strength and corrosion resistance.
316 stainless steel adapters have the best corrosion resistance. They stand up to wet environments, salt water, and harsh chemicals.

Male-Female Round Universal Thread Adapters with Through Hole
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.
