Compression elbow Conex 18x18 mm brass 90° fitting FF-1020401

Conex compression elbow 18x18 mm brass 90° fitting FF-1020401 is a compact right-angle connector designed to join two 18 mm copper or compatible tubes using a mechanical compression joint. The brass body offers corrosion resistance suitable for potable water and heating systems. This 90° compression elbow creates a leak-resistant connection without soldering, making it suitable for installations where fast, reliable assembly and future disassembly are required.

Advantages

The compression elbow provides a reliable mechanical seal that reduces installation time compared with soldered joints and eliminates the need for a heat source. Its brass construction ensures dimensional stability and resistance to scaling and corrosion in typical plumbing and heating environments. The compact 90° design saves space in corners and tight installations while allowing straightforward alignment of pipes. The fitting is compatible with standard compression fittings practice and can be reused or replaced when maintenance is needed.

Suitable for

• Potable water distribution systems
• Domestic and commercial heating pipework
• Tight corner connections where a compact 90° turn is required
• Maintenance, repair and retrofit work on compatible 18 mm tubing

Key specifications

• Material: brass body suitable for plumbing use
• Connection type: compression on both ends
• End diameter: 18 mm x 18 mm
• Angle: 90° elbow
• Application: potable water and heating installations

How to use

Ensure pipe ends are cut square, free from burrs and debris. Slide the compression nut and olive (ferrule) onto each pipe, insert the pipe fully into the fitting until it seats, then hand-tighten the nuts. Use appropriate wrenches to tighten the compression nuts according to standard compression fitting installation practice, taking care not to overtighten. After assembly, check the joint for leaks under normal system pressure and retighten slightly if permitted by the fitting manufacturer’s guidance. For disassembly, loosen the compression nuts and withdraw the pipe; replace olives if they are damaged during removal.

Usage recommendations

Use this Conex 18x18 mm compression elbow in systems designed for mechanical compression fittings and compatible tubing. Verify material compatibility with system fluids and operating temperatures. When installing in concealed or pressurized systems, follow applicable plumbing codes and perform pressure tests after installation. Replace the olive if a leak is detected after initial assembly; do not rely on excessive nut torque to compensate for damaged components.
