Viking Johnson MaxiFit couplings

Home→ Catalog→ Viking Johnson→ MaxiFit→ Couplings

Viking Johnson MaxiFit couplings are designed for connecting pipes with smooth ends (connecting pipes), which have different diameters. They are suitable for various materials, in particular steel, asbestos cement, gray and ductile iron, fiberglass, PVC etc.

Couplings are designed and manufactured under the control of quality management systems in accordance with BS EN ISO 9001. They fully comply with quality standards GOST 12.2.003-91, GOST 356-80, GOST 12815-80, GOST 12821-80, GOST 15763-91.

Main advantages:

  • unique sealing cuff with special ring ribs for easy sliding installation and reliable sealing;
  • resistance to corrosion and damage;
  • universal reaming;
  • pipes may be deflected at an angle of 3° on each side;
  • simple installation;
  • estimated life of 50 years.

Details 		MF689

Application purpose:

  • For connection pipes made of cast iron, steel, PVC, as well as some other materials (pipes made of PE are mounted using a sleeve) in various combinations
  • For neutral liquids at permissible operating temperature + 50 °С

Characteristics:

  • Working pressure up to 16 bar (water) and up to 6 bar (gas)
  • One type of pipe coupling made of different materials
  • The design provides easy and quick installation
  • The gap between the ends of the pipes is necessary to: compensate for thermal expansion, prevent transmission of vibration, compensate for sedimentation and facilitate installation/dismantling

Installation:

  • Pipes are inserted into a freely assembled freely assembled coupling, with a gap between the ends of the pipes of about 20 mm (chamfering not required)
  • Pressure ring bolts tighten all the way

Materials:

  • Pressure ring and adapter housing / Center pipe: Rolled steel according to British standard BS EN 10025-2: 2004 Grade S275
  • Bolts: Steel according to BS EN ISO 898-1: 2009. Material category 4.8
  • Nuts: Steel according to British standard BS EN 4190: 2001 Grade 4
  • Washers: Stainless steel in accordance with BS 1449: Part 2: 1983. Grade 304 S15
  • Sealing collar: EPDM
