About this item
  • Practical element – thanks to the hole spacing in the 126 mm standard, the Kotarbau flange can be used for lying and standing 24l, 50l, 80l, 100l pressure vessels. Our flange is a fundamental structural element of domestic water plants. It is perfect for use with diaphragm pumps.
  • Features – The Kotarbau steel flange is responsible for pressing the membrane in the tank. The membrane seals the pressure vessel and prevents the leakage of water and air thanks to its precise construction. The flange guarantees proper operation of the entire system. On the outside there is a nozzle to which a 1 inch hose is screwed on.
  • Long-term use – the waste construction connection flange is made of galvanised steel, which is characterised by durability and long service life. The working part that comes into contact with water is made of a plastic that has a high resistance to moisture and protects the product from corrosion.
  • Easy to assemble – thanks to the plastic inner lining, the Kotarbbau flange is easier to assemble. The steel flange has 6 mounting holes with 9mm diameter. After mounting the flange, the specific part of the pressure vessel must be filled with air. Remember to check the diameter and distance of the holes in your expansion vessel before purchasing.
  • Technical data – Flange – Diameter of connecting bracket: 1 inch, diagonal distance between holes: 126 mm, hole spacing: 63 mm, diameter of screw hole: 9 mm, number of holes: 6, total diameter: 154 mm, weight: 347 g, material: galvanised steel, plastic

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.
