Gasket NBR, DIN-EN 682 MOP Gas: up to DN 400 = 5 barOther water qualities PFA /PN: up to DN 300 = 16 bar, larger DN 300 = 10 bar

Restrained flange adapter for connecting pipes made of different materials (steel, cast iron, ductile cast iron, asbestos cement, PVC, PE-HD/PEX) in civil engineering.

Housing and follower-ring made of ductile iron (EN-GS-450-10)
Corrosion protection Rilsan (min. 250 µm according to GSK)
One gripping system for all pipe materials gripping segment made of acetal, corundum coated
Sealing material EPDM or NBR
Diameter range depending on size up to max. 54 mm
Stainless steel or galvanized screws and nuts
Angular deflection of 4 degrees
Flange connection dimensions according to DIN EN1092, PN 10 and PN 16

A notice:

When used on PE-HD/PEX pipes, our inner support sleeve SHVA is required.

When used on AZ pipes, restrained cannot be entirely ensured.

Areas of application

FRIAGRIP coupling FGK as a restrained coupling¹ for pipes made of different materials (steel, cast iron, ductile iron, fiber cement², PVC³, PE-HD/PEX⁴). Available from DN 40 to DN 600+.

FRIAGRIP components can only be used in buried areas

Processing instructions

FRIAGRIP, restrained couplings for connections without without abutments (exception: asbestos cement pipes).

The pipe ends must be prepared in accordance with the general installation requirements (see FRIAGRIP installation instructions).

The insertion depths tmin./tmax. must be strictly observed.

¹ Restrained; water: ≤ DN 300 PN 16, > DN 300 PN10 / restrained: ≤ DN 400 PN 5.

² Restrained cannot be guaranteed for asbestos cement pipes

³ For application on PVC gas pipes, see FRIAGRIP Technical Information. For PVC pipes with wall thicknesses < DIN 8061/62 - PN 10, use the FRIAGRIP support liners (type FRIATEC Mod. SHVA).

For application on stainless steel pipes, see FRIAGRIP Technical Information.

⁴ When used with PE-HD/PEX pipes, the FRIAGRIP support liners

Good reasons for FRIAGRIP

Working in Pipe Trenches reduced to a minimum (no abutments required for directional changes)
The components are delivered pre-assembled at the factory, thus no conversion and replacement work is required on site
One gasket-package and one gripping segment for the pipe materials steel, cast iron, ductile iron, fiber cement, PVC, PE-HD/PEX.
Gasket and gripping system operate independently of each other. This ensures a reliable seal under dynamic axial loads.
Specially profiled gasket ensures full seal even on scored and corroded pipes.
Deflection of the pipes up to 8° (coupling) or 4° (flange adapter).
In case of pipe breakage, axial misalignment can be compensated by installing two couplings. The couplings act like a joint and keep the pipe stress-free
Simple installation with standard tools
One torque for all pipe materials
Repeated checking of the tightening torque of the bolts not necessary
The tolerance range of up to 54 mm allows different pipe materials to be connected to one FRIAGRIP-Size, therefore reduced stock-keeping necessary
