Hammer Unions

HMS Engineers manufactures high-quality Hammer Unions from precision steel forgings, using materials carefully selected to meet specific pressure ratings. Designed for quick and secure connections, our hammer unions eliminate the need for flange fittings, making them ideal for mud tank and pipeline applications.

Key Features

• Instant Connection – engineered to join mud tanks quickly and securely without flange connections.
• Non-Leak Seals – even when tanks are misaligned, hammer unions provide tight, leak-proof seals.
• Robust Construction – male part features an external threaded portion welded to the pipe end, while the female part engages via an O-ring for secure sealing.
• High Pressure Capability – O-ring compression in the “D” square cross-section ensures reliable sealing against fluid pressures up to 20,000 psi.
• Ease of Use – hammer-tightened assembly allows for fast installation and adjustment in the field.

Applications

• Mud tank connections
• High-pressure fluid transfer lines
• Oilfield operations requiring quick, secure, and leak-proof connections
