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.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.

Soild
Size: Medium
The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.
