Products - Viking Johnson fittings

MaxiFit (universal pipe couplings) have a wide range of couplings designed to connect pipes of the same nominal width, but different outer diameter and materials (e.q. connection of asbestos-cement and steel pipes, or cast-iron or PVC pipes), as well as connecting the pipes made of same material. That is why they are known as transition couplings, because they allow a transition from one material type to another. They can also connect pipes of the same outer diameter to each other.

MaxiFit (Multifit) pipe coupling consists of the body, two end rings (clamping flanges), rubber gasket and (two) clamping screws. End ring and adaptor body are made out of ductile cast iron (DCI) GGG 45 in accordance with EN-GJS-450-10 standards. The coupling is coated with the organic coating based on Rilsan Nylon (Nylon 11), which is WRAS approved for use with potable water. Bolts and nuts are protected by Silver Sheraplex and can be stainless steel or coated with Teflon optionally.

The minimum and maximum range of MAXFIT pipe couplings and maxiadaptor-flange adaptors

Flange adaptors are designed to join various types of plain end pipes with flanged parts. Flange adaptors consist of the flanged body, end ring (two clamping flanges), rubber gasket and two clamping screws. End ring and adaptor body are made out of ductile cast iron (DCI) GGG 45 in accordance with EN-GJS-450-10 standards. Coated with the organic coating, based on Rilsan Nylon (Nylon 11) is WRAS approved for use with potable water. Bolts and nuts are protected by Silver Sheraplex and can be stainless steel or coated with Teflon optionally. They are produced for pipe diameters ranging from 60 to 600 mm.

These are used to connect PE and PVC pipes. Unlike MaxiFit couplings and Maxidaptor Flange Adaptors, Aquafast couplings and adapters have a gripper for safe connection of PE and PVC pipes.
They are produced for the following pipe diameters: 63, 75, 90, 110, 125, 140, 160, 180, 200, 225, 250 and 315 mm.

It is designed to connect pipes of all material types. They have a very wide range (up to 44 mm) and are equipped with specific sealing system, consisting of a specially designed rubber rings and plastic segments, which ensure the proper seal, even on a extremely damaged pipes with rough surface. Its segments are coated with abrasive material that provides a secure connection, without damaging the tube’s surface.

The minimum and maximum range of Ultragrip fittings and flange adaptors

Support liners are stainless steel inserts, which are used when installing ultragrip and multi joint fittings on PE and PVC pipes.

These support liners, which are mounted inside the pipe, prevent pipe deformation, and at the same time, giving it a perfect shape, thus ensuring high-quality and reliable mechanical joint of flexible pipes such as PE pipes, as well as thin-walled PVC pipes.

Its length can be 300, 400 and 500 mm, or higher upon customer’s request.
