About this item
  • Application: a connector with variable cross section made of plastic is an installation element for ventilation systems with which two sections with different cross sections can be connected in one element. We offer a special connection from rectangular to round pipes that allow you to create a smooth transition from one cross section to another.
  • Construction: We offer a connector with variable cross section with the dimensions 110 x 55 mm and a hole diameter of 100 mm. It is used in ventilation systems with different pipe cross-sections. Variable cross section plastic connectors are used to seamlessly connect sections of different diameters. They allow effective air flow in different sections of the ventilation system.
  • Material: plastic connectors with variable cross section are moisture resistant, which is important for any ventilation system. Plastic does not absorb water, corrode or rust, which means the connectors will last a long time. They are suitable for use in any building from homes and apartments to public facilities.
  • Advantages: plastic connectors with variable cross section are characterised by a very affordable price. In addition, you can easily install these elements yourself and build an efficient ventilation system. Plastic connectors with variable cross section are also resistant to corrosion and the plastic materials used for their production are more resistant to weather and chemical influences.
  • Technical data: width: 110 mm, height: 55 mm, length: 140 mm, diameter: 100 mm, material: plastic, colour: white, weight: 0.09 kg

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
