Hammer Seal Unions

Hammer Seal Unions – Secure Sealing for Rotating and Stationary Equipment

At WellGear Oil Tools, our Hammer Seal Unions are precision-engineered to provide a reliable, high-pressure seal between stationary pipes and rotating or moving equipment such as tanks, pumps, and agitators. Designed for fast, tool-free installation and removal, these unions are ideal for applications requiring frequent maintenance, alignment, or repositioning—without compromising pressure integrity.

🔩 What Sets Our Hammer Seal Unions Apart?
Unlike traditional threaded or flanged connections, hammer seal unions feature a metal-to-metal seal reinforced by a replaceable O-ring or seal ring. The union body is welded or threaded onto the pipe or tank nozzle, while the nut is hammered tight around a grooved hub to form a tight, leak-proof seal—even under pressures up to 10,000 PSI.
