Compression fitting Comap 3/4E-15 for copper pipe, chrome finish (model 8350915)

The Comap compression fitting 3/4E-15 is designed to join 15 mm copper pipe with a secure, mechanically sealed connection. Finished in chrome, the fitting provides surface protection against corrosion and a neat visual appearance where plumbing fittings are visible. It is intended for use in potable water supply and central heating installations that require a compact, reliable compression joint for 15 mm copper tubing.

Advantages

The chrome finish enhances corrosion resistance and simplifies cleaning while maintaining a consistent aesthetic with other chrome-plated fixtures. The compression design provides a tool-assisted, leak-resistant mechanical joint without the need for soldering, making it suitable for retrofit and repair work. Manufactured to fit standard 15 mm copper pipe, the fitting offers repeatable performance and straightforward installation when used with compatible copper tubing.

Suitable for

• Connecting 15 mm copper water supply lines
• Joining copper pipe in central heating circuits
• Retrofit or repair work where soldering is impractical
• Visible plumbing runs that require a chrome appearance

Key specifications

• Material compatibility: copper pipe (15 mm outer diameter)
• Connection type: compression joint
• Finish: chrome-plated surface for corrosion resistance
• Typical applications: potable water and central heating systems
• Installation: mechanical assembly with nut and olive (compression ring)

How to use

Ensure the copper pipe end is cut square and deburred before assembly. Slide the compression nut and olive (compression ring) onto the pipe, then insert the pipe into the fitting body until it seats fully. Tighten the compression nut by hand and then use a wrench to apply the final torque according to standard practice for compression fittings, taking care not to overtighten. After assembly, pressurize the system and inspect the joint for leaks; if leakage occurs, slightly increase torque or disassemble and check the olive and mating surfaces for damage or debris.

Usage recommendations

Use with clean, properly sized 15 mm copper tubing and compatible compression fittings. Avoid excessive torque to prevent deformation of the compression ring. For installations carrying potable water, follow local plumbing codes and flush the system as required before use. In heating systems, ensure the fitting materials and finish are compatible with the fluid and operating temperatures used.
