A hammer union is a high-pressure pipe connection used in oil and gas operations to quickly join sections of flowline, treating iron, or other piping. The union is secured by striking the wing nut with a hammer, creating a fast, reliable, and pressure-rated connection. The internal seal prevents fluid or gas leakage at the joint.
