## Summary description

Perfexim compression coupling model 703 with dimensions 20 x 16 mm. Designed for connecting pipes of different diameters in plumbing systems, this straight coupling provides a mechanical, threaded-free connection using compression fittings. Suitable for domestic and commercial water installations where a secure transition between 20 mm and 16 mm pipes is required.

## Long description

The Perfexim compression coupling 703 20 x 16 mm is a straight transition fitting designed for plumbing systems that require a secure, mechanical connection between pipes of different diameters. The coupling uses a compression mechanism to join a 20 mm pipe to a 16 mm pipe without the need for soldering or threaded joints. It is suitable for potable water installations in domestic and light commercial applications where a reliable, compact coupling is needed.
Advantages
This compression coupling provides a straightforward, tool‑friendly installation and eliminates the need for heat or solvent-based joining methods. Its straight design ensures an even flow path with minimal disruption to system hydraulics when connecting a 20 mm pipe to a 16 mm pipe. The fitting offers a leak-resistant mechanical seal when installed correctly and is appropriate for systems that may require disassembly or future modifications.
Suitable for
Connecting 20 mm supply lines to 16 mm branch lines in potable water systems
Domestic plumbing repairs and upgrades where a non‑threaded transition is required
Light commercial water installations and service lines
Situations requiring removable or replaceable fittings without soldering
Key specifications
Type: Straight compression coupling (reducing)
Connection sizes: 20 mm to 16 mm
Material: metal construction suitable for water systems (see product labelling for exact alloy)
Sealing method: compression ring / olive mechanical seal
Intended media: potable water and general plumbing fluids compatible with the material
Installation: push/insert pipes and tighten compression nut to create seal
How to use
Ensure pipe ends are clean, cut square and deburred before assembly. Slide the compression nut and compression ring (olive) onto each pipe end, insert the pipe fully into the coupling body until it seats, then hand‑tighten the nuts. Use appropriate wrenches to tighten the nuts further according to the manufacturer’s recommended torque or until a firm mechanical seal is achieved; avoid over‑tightening. After installation, pressurize the system and check for leaks. If necessary, slightly tighten the nuts to correct minor leaks, then recheck.
Usage recommendations
Use this coupling in accordance with local plumbing codes and the pipe manufacturer’s guidelines. Verify compatibility with the pipe material and the operating pressure and temperature of the system. Where frequent disassembly is expected, inspect the compression rings periodically and replace them if deformation or leakage is observed.
