As a manufacturer and producer of pipe fittings for over 20 years, fireminus can provide you with high quality pipe fittings at low prices.
The Grooved Reducing Cross With Female Threaded Branch combines a grooved body with a female threaded branch for hybrid connections in piping systems.The Grooved Reducing Cross With Female Threaded Branch seamlessly integrates grooved piping (via a fixture) and threaded components (e.g., valves, sensors). Grooved Reducing Cross With Female Threaded Branch seamlessly integrates grooved piping (via fixtures) and threaded components (e.g., valves, sensors), making it ideal for retrofit or multi-connection applications in heating, ventilation and air conditioning (HVAC), industrial and fire protection systems.
Grooved Reducing Cross With Female Threaded Branch
- Wide range of pressure resistance (carbon steel ≤ 300 psi, stainless steel ≤ 600 psi) and temperature resistance covering -40°F to 800°F.
- Triple seal design (C-rubber seal + groove + thread seal) ensures leak-proof performance in high-pressure environments.
- Suitable for HVAC, fire protection, chemical, petroleum and many other fields, support corrosive media environment.
- Suitable for galvanized steel pipe, stainless steel pipe, copper pipe and many other pipe materials, compatible with NPT/BSP thread standards.
- Installation efficiency is 30%-50% higher than flange connection, no need for secondary galvanization or complicated tools.
Key Points to Note
Installation Standards
Thread alignment: Ensure precise alignment of the female-threaded branch to prevent cross-threading, and apply torque within 15–30 ft-lbs for proper sealing.
Groove specifications: Verify groove depth (1.5–3.0 mm) and width match clamp requirements (e.g., Victaulic-compatible designs) to avoid mechanical stress.
Material Selection
Corrosive/High-temperature environments: Opt for stainless steel 316L instead of galvanized carbon steel to prevent coating degradation in chemical or marine settings.
Fire protection systems: Use UL/FM-certified fittings, and prioritize full-grooved main pipes ≥DN100 for structural integrity.
System Compatibility
Hybrid connection checks: Confirm pressure ratings and chemical compatibility between grooved and threaded components (e.g., ANSI vs. ISO threads) to avoid localized overpressure.
Seal maintenance: Inspect rubber gaskets every 5 years for aging or deformation, especially in systems with thermal cycling.
