Figure 400 | 4,000 PSI Hammer Union
C&C Industries
The C&C Figure 400 Hammer Union is a high-pressure union designed for demanding oilfield and industrial applications up to 4,000 PSI. Featuring a precision ball-and-cone metal-to-metal sealing design, it provides a secure and reliable seal under elevated pressure conditions.
Available in sizes from 2” through 12” with threaded and butt-weld configurations, the Figure 400 is built for strength and durability in systems where standard unions are not sufficient. Its robust construction and proven sealing geometry make it a reliable choice for higher pressure service.
Designed for oil, gas, and water applications, the Figure 400 is commonly used in production systems where consistent sealing and structural integrity are critical.

PERFORMANCE ADVANTAGES
Why the FIG 400 Performs Where It Counts
HIGHER PRESSURE CAPABILITY FOR
DEMANDING SYSTEMS
The 4,000 PSI rating allows this union to operate safely in applications where lower-rated unions would be at risk of failure, providing a necessary upgrade for higher-pressure systems.
BALL-AND-CONE SEALING FOR POSITIVE
METAL-TO-METAL CONTACT
The sealing geometry ensures uniform contact under pressure, improving sealing reliability compared to flat-face or basic seating designs.
STRUCTURAL STRENGTH
FOR HEAVY-DUTY APPLICATIONS
The robust construction supports higher loads and stress conditions, making it suitable for production systems where pressure and mechanical forces are elevated.
SCALABLE ACROSS MULTIPLE LINE SIZES
With availability up to 12”, the Figure 400 can be used across a wide range of piping systems, allowing standardization within high-pressure operations.
