Expansion plug DN 250mm - SMU S

Code article : 157060

Description

The SMU S expansion plugs are used to temporarily or definitively seal the pipes and fittings located inside the aperture, used on gravity drainage networks. The resistance to accidental pressure of the expanding plug is 0.2 bar without additional device. If necessary, the locking of this plug is carried out by means of the specific grip collar which can accommodate thrust pressures up to 10 bars depending on plug type.
