Nickel-Plated Brass Hex Nipple (MxM)
Nickel-Plated Brass Hex Nipple (MxM)
Connect two female-threaded plumbing fittings, valves, or pipe ends with our Premium Nickel-Plated Forged Brass Hex Nipple. Precision hot-forged from high-grade lead-free brass and protected by a sandblasted nickel electro-plating, this double male (M×M) threaded adapter serves as a heavy-duty joiner for fluid, gas, and pneumatic supply lines.
Featuring standard male BSP parallel/tapered threads (ISO 228-1) and a sturdy central hexagonal wrench collar, this hex nipple allows high-torque spanner tightening without damaging or distorting the threaded ends. The thick nickel-plated layer provides superior protection against dezincification, hard water mineral scaling, atmospheric oxidation, and galvanic corrosion. It is an indispensable fitting for connecting angle valves, flexible hoses, water filter manifolds, pump lines, compressed air drops, and solar water heaters across Saudi Arabia and the GCC.
Key Features
-
Heavy-Duty Forged Brass Core: Hot-forged from high-density brass (CW617N / HPb59-1) for high mechanical strength, pressure tolerance, and thermal expansion resistance.
-
Corrosion-Resistant Nickel Plating: Multi-layer nickel-plated finish prevents surface oxidation, tarnish, chemical erosion, and lime-scale buildup in hot and cold water systems.
-
Integrated Center Hexagon Nut: Precision-machined hexagonal wrench collar provides a solid grip for open-end wrenches or sockets during installation.
-
Precision BSP Tapered/Parallel Male Threads: Clean, deep-cut ISO 228-1 male threads ensure smooth Teflon tape wrapping and 100% watertight/airtight sealing under high pressure.
-
Versatile Application: Ideal for connecting female-threaded valves, water filters, pressure pumps, garden spigots, bidet spray adapters, and pneumatic equipment.
