The SPI Flexible Rubber Radiator Drain Down Tub (SEL9235) is a mess-free, time-saving solution for draining radiators during plumbing and heating maintenance. Designed for real-world site conditions, this flexible tub fits snugly onto 10mm, 12mm, 15mm and 22mm pipes, making it a versatile essential for installers, service engineers, and DIY users.

With a generous 14 litre capacity, it reduces the need for constant emptying and helps keep jobs clean and controlled. The tub’s self-sealing flexible flange adapts to different pipe angles to create a reliable seal every time — even on horizontal pipes or awkward, tight-access radiators. That means no extra rubber seals, grease, or fiddly add-ons required.

Built from durable flexible rubber, the PlumbTub is made for repeated use, easy cleaning, and dependable performance on every drain-down. Whether you’re swapping a radiator, changing valves, or servicing a system, this tub makes the job quicker, cleaner, and far less stressful.
