This Bonfix reducing coupling is used with water pipes, gas pipes, heating installations or industrial transport systems. A reducing coupling is used to create a transition between 2 pipes of different diameters.

With brass compression fittings you can easily create a safe and leak-free connection between 2 pipes, without welding, soldering or pressing. It is possible to reuse the compression fitting, but the compression ring must be replaced.

In addition to this reducing coupling, the range includes various other couplings, such as:
  • Compression ring.
  • Elbow 90°.
  • Support sleeve.
  • Tee 90°.
  • Union nut.

Installation

With a brass compression coupling, you can easily create a strong and reliable connection without needing special tools. All you need is a spanner to tighten the coupling, a pipe cutter to cut the pipe to size, and a deburring tool to smooth the edges. The compression ring in the coupling ensures a leak-free connection.

The installation of a compression fitting in a water pipe follows these steps:
  • Cut the pipe to size and deburr the ends to prevent any damage to the pipe.
  • Slide the pipe into the compression fitting until it reaches the stop edge.
  • Hand-tighten the compression nut.
  • Then tighten the compression fitting with a wrench;
  • 12 and 15 mm: one full turn.
  • 22 mm: half to three-quarters turn.
  • 28 mm or larger: approximately three-quarters turn.
Please note: If the gland is tightened too much, there is a risk of leakage. When using a soft red copper or plastic pipe, we recommend using a support sleeve to prevent the pipe from being compressed.

Exceeded my expectations in every way.
Size: 200-Foot, Style: 14-Gauge, Size: 200-Foot, Style: 14-Gauge
Great quality solid copper cables. None of the local stores, such as Walmart or Autozone had Any real copper cables at all. All offerings were CCA dual-conductor cables that are essentially 95% aluminum. 2/3rd of available options had Packaging that didn't openly disclose this fact. It took time researching each "high-performance", or "professional grade" audio cables they had in stock. Perhaps, there's no regulations that require manufacturers to to make any reference clarifying that the product isn't pure copper. It was surprisingly misleading. Amazon Basic branded cables are as good as the best cables you cables you can buy elsewhere online. 14 Gauge us about as thick as you could reasonably use at home without it becoming a major annoying mess. Great price as well. Made in Vietnam - is just the icing on the cake. Ordered the "used" option. Cables were brand new, the coil was slightly banged up in shipping and dusty, thus the 15% discount
