Hawle undrilled saddles serve to close "old" boreholes and to repair pitting corrosion spots in DCI, steel and AC pipes DN 65 - DN 500.
Adaptation to the main pipe is effected via holding strap and saddle gasket (e.g. model no. 310 or model no. 311) of the appropriate nominal width.
Max. borehole/leakage: 45 mm
