Nickel-Plated Brass Female Threaded Socket (FxF)
Nickel-Plated Brass Female Threaded Socket (FxF)
Seal off open male-threaded pipe ends, manifold ports, and valve outlets securely with our Premium Nickel-Plated Forged Brass Threaded Female Cap. Precision hot-forged from high-grade lead-free brass and finished with a durable sandblasted nickel electro-plating, this internal female-threaded (F) cap provides a 100% watertight and pressure-resistant dead-end closure for plumbing, heating, and pneumatic supply systems.
Featuring deep precision-cut female BSP parallel threads (ISO 228-1) and an integrated hexagonal wrench collar, this female end cap allows high-torque spanner tightening without slipping or distorting the fitting body. The thick nickel-plated layer delivers superior protection against dezincification, hard water mineral scaling, atmospheric oxidation, and galvanic corrosion. It is an essential component for capping water meter ports, manifold outlets, solar heating lines, pressure test setups, and future expansion branch lines across Saudi Arabia and the GCC.
Key Features
-
Heavy-Duty Forged Brass Construction: Manufactured from high-density forged brass (CW617N / HPb59-1) to withstand extreme internal static pressure, temperature fluctuations, and water hammer.
-
Corrosion-Resistant Nickel Finish: Multi-layer nickel electro-plating guards against oxidation, rust, lime-scale accumulation, and chemical degradation in hot and cold water systems.
-
Integrated Hexagonal Wrench Collar: Precision-machined outer hex flats allow fast, slip-free wrench engagement during installation and system maintenance.
-
Precision BSP Female Threads: Clean, deep ISO 228-1 female threads ensure smooth engagement with Teflon tape, thread cord, or rubber washers for zero-leak sealing.
-
Multi-System Compatibility: Ideal for temporary or permanent pipe line isolation in domestic water supplies, HVAC chilled loops, compressed air networks, and irrigation lines.
