Pipe Repair products offer a fast, safe way to seal splits, holes, and corroded sections instantly – often under full system pressure – avoiding the need for expensive and time-consuming network shutdowns.
QuickFit Flange Adaptors connect flanged fittings to steel and ductile iron pipes, featuring multi-standard drilling, quick installation, 3° angularity, and optional anchoring for efficient new pipeline projects.

DN50 to DN300 = to customer specification up to 46 bar
Flange Drilling = PN10/16 as standard and others to customer specification
There are restrictions on the minimum thickness of the stainless steel and PVC-U pipes for them to work with Viking Johnson flexible couplings. Consult Viking Johnson for further guidance.
Caveat 3
While Viking Johnson has tested and approved the use of QuickFit on gas, please verify that the network owner sanctions the use of the fitting for your intended application.

Efficient Pipe Jointing for High-Pressure Networks
Simple Design
The QuickFit Flange Adaptor range is engineered to connect plain-ended pipes to flanged equipment. Supplied pre-assembled with close tolerance design, QuickFit allows rapid installation while maintaining reliable sealing performance for potable water, wastewater and industrial applications.
New Lay & High Pressure Applications
QuickFit Flange Adaptors are ideal for new lay installations and high-pressure applications. DN50–DN125 sizes are rated up to 46 bar, while DN150–DN300 sizes are rated up to 29 bar as standard, with higher pressure options available as fabricated specials.
Easy & Safe to Fit
Installation requires no specialist skills. One captive, non-rotating bolt size (19mm A/F) is used across the entire range, requiring only a single torque wrench, reducing installation time and simplifying tool requirements on site.
High Performance
QuickFit Flange Adaptors accommodate angular deflection of up to 3° and allow axial movement of up to 5mm, helping absorb ground settlement, thermal expansion and pipeline movement while maintaining joint integrity.
Why Choose QuickFit Flange Adaptors
Simple Installation – Rapid installation with a close-tolerance, pre-assembled design and single bolt size across the entire range for easy installs.
Designed for water and wastewater treatment works – one fitting connects the most commonly used pipe materials, including steel, coated steel and ductile iron.
Full bore flange – Supplied as standard for wafer valve compatibility
Low-profile end ring – Allows use with tie rods without notching
Built in flexibility – For angular deflection and thermal movement
Reduced stockholding – a single fitting covers multiple pipe materials whilst offering both PN10 and PN16 drilling patterns and flexible or tied configurations as standard.
Potable water approved – WRAS & KIWA certified
Design Benefits
Flexible Flange Drilling
As standard the flange adaptors are multi drilled to accommodate BS EN 1092-2 PN10 & 16. Flange drilling to other standards available to accommodate site requirements
End Load Forces Easily Accommodated
Low profile end ring means no interference with tie rods used to harness the flange adaptor to accommodate end load forces.
Gasket Options
EPDM water-approved gaskets are supplied as standard, with Nitrile and specialist gasket materials available for alternative applications and environments.
Simple to Fit
One size of captive, non-rotating bolt across whole range requiring a single spanner to install along with one bolt torque across range.
Designed for Durability
All metal components are coated with Rilsan Nylon 11 which provides excellent corrosion resistance, impact protection and long-term durability. Nuts and bolts are Sheraplex coated to prevent galling and allow repeated re-use.
