These metric coupling nuts have good chemical resistance.

More corrosion resistant than 18-8 stainless steel coupling nuts, these metric nuts have excellent resistance to chemicals and salt water.

Stainless steel coupling nuts have excellent corrosion resistance in most environments.

Increase or decrease metric thread size from one male-threaded part to another. Commonly used to connect two differently sized threaded rods, they have a hex-shaped body, so you can tighten them with a standard wrench.

Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench.

The through hole allows you to connect float rods to float valves.

Connect male- and female-threaded parts of different thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through.

Join two female-threaded parts of various thread types and sizes, while allowing air, liquids, wire, or other thin materials to pass through.

Twist these adapters onto female metric threads to change pitch or switch thread sizes.
