The 32mm & 40mm Bung is a simple and effective blanking plug designed to seal open waste pipes during installation, testing, or maintenance work. Suitable for both 32mm and 40mm waste systems, it provides a secure temporary or permanent seal depending on application.
Manufactured from durable rubber or flexible plastic (depending on variant), the bung ensures a tight fit inside the pipe to prevent leaks, odours, or debris entering the system. It is commonly used in basin, sink, and general plumbing waste installations.
Ideal for plumbers and installers, this bung is a must-have accessory for pressure testing, system isolation, and unfinished pipework protection.
