Features of High Pressure Hammer Unions
High-Pressure Load-Bearing Capacity
High-Pressure Hammer Unions are forged from one-piece alloy steel and rated up to 15,000 PSI, ensuring stable sealing and leak-free performance under high-pressure fluctuation conditions.
BUNA-N Sealing System
The replaceable lip-type BUNA-N seal separates the sealing surface from metal contact, reducing wear and extending service life by about 30%.
Precision Thread Machining
LP/NPT threads are CNC-machined with ±0.2 mm tolerance, ensuring tight engagement and minimizing leakage risk under high pressure.
Rapid Assembly and Disassembly
The hammer-type wing nut structure enables tool-free installation and removal, improving on-site efficiency by around 40% compared to flange connections.
