Slot couplings (rigid) red and galvanized - 8400

The grooved coupling (rigid) is specially designed to create a rigid, twist-proof pipe connection. The grooved couplings (rigid) meet the specific requirements of rigid steel pipe systems to a particularly high degree. The robust lightweight housing creates a secure and rigid connection of grooved pipes / fittings (elbows / T-pieces / reducers / tapping clamps etc.).

Grooved couplings (rigid)
Dimensions DN 32 - DN 250
Surfaces galvanized or painted red RAL 3000 (similar)
EPDM seal, pressure rating PN 16, operating temperature -34°C - 110°C.

Approvals: VdS / FM

Catalog: Section 5.0


Slot couplings (flexible) red and galvanized - 8000

The grooved coupling (flexible) is specially designed to create a flexible pipe connection. The grooved couplings (flexible) meet the specific requirements of the pipe systems of sprinkler systems with grooved pipes / fittings (bends / tees / reducers / tapping clamps etc.).

Grooved couplings (flexible)
Dimensions DN 32 - DN 250
Surfaces galvanized or painted red RAL 3000 (similar)
EPDM seal, pressure rating PN 16, operating temperature -34°C - 110°C.

Approvals: VdS / FM

Catalog: Section 5.0


Grooved couplings (reduced) red and galvanized - 8010

The grooved coupling (reduced) is specially designed to connect two different pipe/fitting diameters directly to each other. Separate reducing fittings and couplings are not required. The grooved couplings (reduced) meet the specific requirements for effective, cost-conscious and fast installation of sprinkler pipe systems.

Grooved couplings (reduced)
DN 65 / DN 50 - DN 150 / DN 100
Surfaces galvanized or painted red RAL 3000 (similar)
EPDM seal, pressure rating PN 16, operating temperature -34°C - 110°C.

Approvals: VdS / FM

Catalog: Section 5.0
