The 32mm Push-Fit Soil Internal Rubber Boss Adaptor is a specialized elastomeric reducer designed to adapt a standard open boss socket (on 110mm soil stack branches, strap-on bosses, or boss pipes) down to accept a 32mm waste pipe connection.
 
It pushes directly into the internal recess of an open 110mm soil boss. The adaptor's flexible outer ribbed fins compress tightly against the inner wall of the boss to create a gas- and watertight seal. The central opening accepts the plain spigot end of a 32mm waste pipe (typically from bathroom wash hand basins or bidet discharges), retaining it securely through push-fit compression without requiring solvent weld adhesive or specialized installation tools.
 
Manufactured from durable EPDM synthetic rubber in accordance with UK standards (BS EN 1329-1 / BS 4514), this flexible adaptor accommodates pipe expansion and vibration while maintaining a seal against foul drainage gases.
