This straight boss adaptor is designed for joining a 40mm waste pipe directly into a soil stack within plumbing and drainage systems. Manufactured from PVC in a grey finish, it provides a practical solution for integrating waste connections in residential projects.
Typically used on site to create a secure branch connection for baths, sinks, or showers into existing soil stacks, this adaptor is suited to both new installations and refurbishment work. Its solvent-weld fitting ensures a rigid, permanent joint for reliable waste management.
