Elbow 45° ODLEWNIA NW 1½" (DN40) galvanized model 22

Galvanized 45° elbow by ODLEWNIA, model 22, for NW 1½" (DN40) piping. This cast fitting is designed to connect two threaded pipes or fittings and redirect fluid flow at a 45-degree angle. Its zinc coating provides corrosion resistance for indoor and outdoor plumbing and heating installations where a durable, threaded connection is required.

Advantages

The ODLEWNIA 45° elbow is made from cast metal and finished with a corrosion-resistant zinc layer, which increases durability in moist or outdoor environments. The threaded design simplifies assembly and disassembly without special welding or soldering tools. Its standardized DN40 outer diameter and 1½" nominal width make it compatible with many common plumbing and heating systems, enabling reliable directional changes with minimal pressure loss compared with sharper-angle fittings.

Suitable for

• Plumbing systems requiring a 45° directional change for water supply or drainage
• Heating installations, radiators, and boiler pipework with DN40 connections
• Indoor and outdoor applications where a galvanized, threaded cast fitting is preferred
• Repair and replacement of existing threaded piping runs

When it may not be suitable

This elbow is a threaded cast fitting with a zinc coating and is intended for typical plumbing and heating fluids. It may not be suitable for systems that require stainless steel, plastic, or specialty corrosion-resistant alloys for aggressive chemicals or high-purity fluids. It is also not intended for applications that demand welding or seamless fittings rather than threaded connections.

Key specifications

• Angle: 45°
• Material: cast metal with zinc (galvanized) coating
• Nominal width: 1½" (NW 1½")
• Diameter designation: DN40
• Connection type: threaded (nut/ screw-fit type)
• Intended use: plumbing and heating piping

How to use

Prepare mating threaded pipes or fittings by cleaning threads and applying appropriate thread sealant or tape recommended for the fluid and pressure in the system. Align the elbow to achieve the required 45° change in direction and hand-start the threads to avoid cross-threading. Tighten to the torque appropriate for galvanized cast fittings using a wrench; avoid overtightening to prevent thread or fitting damage. Inspect joints for leaks after pressurizing the system and retighten if necessary according to installer best practices.

What to consider before purchase

• Compatibility of DN40 / 1½" threaded connections with existing piping
• Material suitability (galvanized cast metal) for the fluid type and exposure conditions
• Required thread sealant type for the intended application and pressure
• Space and routing constraints where a 45° elbow will be installed

Usage recommendations

For reliable performance, use appropriate thread sealant, avoid excessive torque when tightening, and check for corrosion in outdoor or exposed installations during routine maintenance. Select this galvanized 45° elbow when a durable, threaded directional fitting is required for DN40 (1½") plumbing and heating systems.
