Heavy (S) Reducing Coupling
Thes hydraulic compression heavy series reducing coouplings conform to DIN 2353/ISO 8434-1, are manufacutred from plated steel. These straight reducing couplings are compression x compression. These fitting include the body, nuts and olives to provide the complete coupling.
Pipe screw joints and accessories have been improved by constant developments to achieve DIN 2353/ISO 8434-1.
The Range of size: 4 mm to 8 mm (LL) extra heavy, 6 mm to 42 mm (L) heavy and 6 mm to 38 mm (S) heavy series.
