As a manufacturer and producer of pipe fittings for over 20 years, fireminus can provide you with high quality pipe fittings at low prices.
Grooved Straight Cross (Equal Cross) features grooved connections on all four ports, enabling vertical four-way flow splitting or merging of piping systems for applications such as fire protection, HVAC and industrial networks. Its symmetrical design allows for simple installation, compatibility with standard grooved clamps, eliminates the need for soldering, and supports quick disassembly and system expansion for high flow scenarios.
Grooved Straight Cross (Equal Cross)
- The combination of grooved main interface and threaded branch design seamlessly connects grooved piping systems to threaded valves/equipment, reducing the need for welding and increasing installation efficiency by 30%-50%.
- Ductile Iron (ASTM A536) is hot-dipped galvanized for superior corrosion resistance to ordinary carbon steel and is suitable for temperatures ranging from -20°F to 400°.
- Pressure ratings cover 150-600 psi to meet the needs of fire protection, HVAC and industrial high pressure systems.
- FM/UL/CE certified to ANSI/AWWA C606, ASME B16.28 and other standards to ensure tightness and long-term stability.
- The groove interface needs to ensure the surface roughness ≤ Ra 3.2 μm to avoid clamp seal failure.
Pressure Rating and Wall Thickness
Regular Pressure: 150 psi (SCH10 wall thickness) to 300 psi (SCH40 wall thickness)
High Pressure Version: 600 psi (SCH80 wall thickness, thickened port connection area required)
Thread compatibility
Thread Standard: Supports G series (e.g., G1/2 large diameter 20.955 mm, center diameter 19.793 mm, bottom hole recommended 19 mm).
American Standard Threads: NPT threads are suitable for DN15-DN150 branch connections.
