Steel threaded nipple GEBO 1/2" double‑ended 0.5 m black (MPN 70.500.04S)

Steel threaded nipple GEBO 1/2" double‑ended 0.5 m black is a straight, rigid pipe connector with 1/2-inch male threads on both ends and a half‑metre length. Manufactured from steel and finished in a black coating, this threaded nipple is intended to create a secure, durable connection between threaded pipes, valves and fittings in plumbing, heating and industrial systems where a solid steel join is required.

Advantages

This steel threaded nipple offers mechanical strength and dimensional stability typical of steel fittings, ensuring long service life under static load. The double‑ended 1/2" male threads simplify installations that require a straight run between two female threaded components, removing the need for additional couplings. The black finish provides basic surface protection and a uniform appearance that can suit exposed or concealed installations.

Suitable for

• Connecting 1/2" female threaded pipes in plumbing systems
• Linking valves and fittings with 1/2" female threads in heating circuits
• Creating rigid threaded runs in industrial or workshop piping
• Temporary or permanent extensions where a solid steel connector is required

When it may not be suitable

This threaded nipple is a rigid steel piece and is not intended for flexible connections or where vibration isolation is required. It may not be suitable for applications requiring corrosion-resistant materials such as stainless steel or non‑metallic piping in aggressive chemical environments. For threaded connections that require sealing with soft gaskets or compression fittings, additional sealing materials or adapters may be necessary.

Key specifications

• Material: steel
• Thread type: male threads on both ends, 1/2" diameter
• Length: 0.5 m (500 mm)
• Finish: black coating
• Configuration: double‑ended straight nipple

How to use

Prepare mating female threads by cleaning and ensuring they are free of debris. Apply an appropriate thread sealant or tape to the male threads if required by the system (follow the sealant manufacturer's instructions). Thread the nipple into the first female fitting by hand until engaged, then tighten using suitable wrenches on the hex or flats if present, taking care not to over‑torque. Align and thread the opposite end into the second female component and tighten to the appropriate torque. After installation, inspect for leaks and retighten or reseal as needed.

What to consider before purchase

• Confirm compatibility of thread standard and pitch with existing fittings
• Verify that steel material and black finish meet corrosion resistance requirements for the installation environment
• Ensure 0.5 m length is suitable for the intended run without additional couplings
• Decide on appropriate thread sealant or locking method for the fluid and pressure conditions

Usage recommendations

Use proper thread sealants compatible with the conveyed medium and system pressure. For pressure systems, perform a pressure test after installation and recheck torque values after the first service cycle. Store unused fittings in a dry area to prevent surface corrosion of the black finish.
