Pipe elbow Margo Kolano hamburskie DN015 21.3x3.2-1/2 — steel fitting for 21.3 mm nominal diameter

Margo Kolano hamburskie DN015 21.3x3.2-1/2 is a steel pipe elbow designed for use with DN15 piping (nominal diameter 21.3 mm) and a wall thickness of 3.2 mm. The fitting provides a compact angled connection compatible with 1/2-inch threaded systems, enabling secure direction changes in plumbing, heating and industrial fluid circuits. Constructed from steel, the elbow is intended to offer durability and consistent dimensional compatibility for conventional 21.3 mm nominal pipework.

Advantages

The steel construction ensures mechanical strength and resistance to deformation under typical operating conditions. Its dimensional match to 21.3 mm nominal pipes and 3.2 mm wall thickness supports reliable alignment and sealing with standard components. The 1/2-inch thread-compatible connection simplifies integration into existing threaded piping systems and reduces the need for additional adaptors. The compact elbow shape conserves space while maintaining flow characteristics suitable for general plumbing and heating applications.

Suitable for

• Residential and commercial plumbing installations using DN15 (21.3 mm nominal) pipe
• Heating circuits where compact angled connections are required
• Industrial fluid systems compatible with steel fittings and 1/2-inch threaded connections
• Maintenance and repair tasks replacing or rerouting short sections of 21.3 mm nominal piping

Key specifications

• Material: steel
• Nominal size: DN15 (21.3 mm nominal diameter)
• Pipe wall thickness compatibility: 3.2 mm
• Connection type: compatible with 1/2-inch threaded systems
• Component type: elbow (angle fitting)

How to use

Confirm that the existing piping matches the nominal diameter (21.3 mm) and wall thickness (3.2 mm) before installation. Prepare mating threads and sealing surfaces by cleaning and, if required by the system, applying the appropriate thread sealant or tape. Thread the elbow into the mating component or pipe end by hand to start, then tighten with suitable tools to the torque recommended for the thread and material to ensure a leak-free joint. Verify alignment of the elbow to achieve the intended change of direction and test the assembled circuit at working pressure according to local codes and standards.

Usage recommendations

Use with compatible steel piping and adhere to applicable plumbing or heating installation standards. Do not expose the fitting to incompatible chemicals or environments that may accelerate corrosion. For high-pressure, high-temperature, or specialized fluids, consult system specifications to confirm material suitability and sealing method.
