Opal 90° cast elbow threaded 4" galvanized, weight 3.25 kg, model G92 100

Opal 90° cast elbow threaded 4" galvanized is a cast iron pipe fitting designed to change the direction of a pipeline by ninety degrees. The fitting features a threaded connection and a galvanized finish, with a nominal size of 4" and a mass of 3.25 kg. It is intended for use in fluid and gas systems where a robust, threaded galvanized elbow is required and where corrosion resistance is important, such as industrial plumbing, heating circuits and outdoor installations.

Advantages

The cast construction provides mechanical strength and dimensional stability while the threaded connection enables straightforward assembly and disassembly without welding. Galvanized coating enhances resistance to atmospheric corrosion and extends service life in damp or outdoor environments. The compact 90° geometry allows efficient direction changes in tight routing layouts and the standardized nominal size ensures compatibility with matching threaded pipe components.

Suitable for

• Industrial plumbing and piping systems
• Heating and boiler connections
• Outdoor and exposed installations requiring corrosion resistance
• Temporary or permanent threaded pipe assemblies

Key specifications

• Angle: 90° elbow
• Material: cast iron (cast fitting)
• Connection type: threaded
• Nominal size: 4 inches
• Surface finish: galvanized coating for corrosion protection
• Weight: 3.25 kg

How to use

Prepare mating threaded pipe ends by cleaning threads and applying an appropriate sealing method such as thread sealant tape or pipe thread compound compatible with the conveyed medium. Screw the elbow onto the mating thread by hand and then tighten with suitable pipe wrenches until a secure, leak-minimized joint is achieved; avoid over-torquing to prevent thread damage. Verify alignment before final tightening to ensure the 90° orientation matches intended routing. For installations exposed to weather, ensure the galvanized surface remains intact and consider additional protective measures at cut or abraded areas.

Usage recommendations

Use this threaded galvanized elbow in systems within the temperature and pressure limits appropriate for cast iron fittings and the sealing method selected. Inspect threads for wear or damage prior to installation and replace fittings that show significant corrosion, cracks or deformation. For gas systems or safety-critical applications, follow applicable regulations and use qualified personnel for installation and pressure testing.
