Opal elbow 90° cast 1" x 1/2" black, model B90R 25X15, weight 0.195 kg

Opal elbow 90° cast 1" x 1/2" black (model B90R 25X15) is a right-angle cast fitting designed to change the direction of threaded pipe runs where two different nominal sizes must be joined. The fitting features a 1" to 1/2" transition and a black finish, providing a compact, durable connection point for domestic and light commercial plumbing installations. Weighing 0.195 kg, the elbow is suitable for use in systems that require a sturdy threaded elbow to route flow at a 90° angle while accommodating mixed-diameter piping.

Advantages

The cast construction ensures mechanical strength and resistance to deformation under normal installation loads, while the threaded connections allow straightforward assembly and disassembly without special tools. The compact 90° design minimizes the footprint in tight spaces and simplifies routing of pipes around obstacles. The black finish provides basic surface protection and a uniform appearance when installed with matching fittings.

Suitable for

• Connecting a 1" threaded pipe to a 1/2" threaded pipe at a 90° angle
• Domestic water supply and heating branch lines
• Light commercial plumbing where mixed diameters are required
• Tight installation spaces requiring a compact elbow

Key specifications

• Angle: 90°
• Connection sizes: 1" to 1/2" (threaded)
• Material: cast metal
• Finish: black
• Weight: 0.195 kg

How to use

Prepare mating threaded pipe ends by cleaning threads and applying an appropriate sealing method such as PTFE tape or thread sealant compatible with the system medium. Thread the elbow onto the larger or smaller pipe as needed, tighten by hand and then use a suitable wrench to achieve a secure, leak-free joint without over-tightening. Align the elbow so that the outlet orientation matches the required direction before final tightening.

Usage recommendations

Use this cast elbow only with compatible threaded pipe sizes and materials. Verify system pressure and temperature limits for the piping and fittings in the installation. When installing in potable water systems, ensure any thread sealant used is approved for drinking water if required. Periodically inspect threaded connections for leaks and integrity, especially after initial pressurization and thermal cycling.
