## Summary description

Comap compression union 3/4E-15z (MPN 835915) is a nickel-plated pipe fitting with a flexible sealing ring designed for reliable sealed connections in plumbing and heating systems. The union provides mechanical joining of compatible 3/4-inch pipes or fittings, ensuring leak-resistant joints where disassembly or maintenance may be required.

## Long description

Comap compression union 3/4E-15z with flexible ring, nickel-plated is a mechanical pipe fitting intended to join compatible 3/4-inch plumbing and heating pipes or fittings. The nickel-plated surface provides corrosion resistance and a smooth finish, while the integrated flexible sealing ring ensures a tight, leak-resistant connection that can be disassembled for maintenance or reconfiguration. The compact design is suitable for confined installation spaces and for systems where a reliable compression joint is required without soldering or threading.
Advantages
The compression union creates a secure, pressure-resistant joint using a flexible sealing ring that adapts to minor surface irregularities, reducing the risk of leaks. Nickel plating enhances durability and resistance to corrosion in domestic and light commercial installations. The union supports quick installation and later disassembly, enabling maintenance or replacement without extensive pipework alterations. Its mechanical joining principle eliminates the need for heat-based joining methods, making it suitable for installations where open flame or soldering is undesirable.
Suitable for
Connecting compatible 3/4-inch plumbing and heating pipes
Situations requiring periodic disassembly or maintenance
Installations in tight or confined spaces
Systems where soldering or threaded joints are impractical
Key specifications
Connection size: 3/4-inch compatible
Type: compression union with flexible sealing ring
Finish: nickel-plated surface for improved corrosion resistance
Material: metal body with elastomeric sealing ring
Application: potable water, heating and general plumbing systems (subject to local regulations)
How to use
Ensure pipe ends are cut square, deburred and clean before assembly. Slide the union components onto the pipes, position the flexible sealing ring between the body and the ferrule, then tighten the compression nut until the joint feels secure and leak-free. Follow recommended torque or hand-tightening guidance from the system designer or local practice to avoid over-tightening. After assembly, pressurize the system and inspect the joint for leaks. If disassembly is required, release the compression nut and remove the union components for access or replacement.
Usage recommendations
Use only with compatible pipe materials and dimensions; verify material compatibility for the transported medium and follow local plumbing codes. For permanent or high-temperature applications, confirm suitability of the sealing ring material. Periodically inspect visible joints for signs of corrosion or leakage and retighten or replace components as needed.
