Opt for maximum durability with our selection of screw-on brass overflows for 1000 liter tanks. Unlike plastic solutions, brass offers superior resistance to temperature variations, freezing and frequent handling. It is the ideal choice for professional installations or demanding individuals who want a permanent solution to prevent overflow of their tank.
Our brass overflow fittings guarantee a perfect seal thanks to their robust design and high-performance seals. Easy to install on the top of your IBC pocket or on a lid, they allow you to create a secure drain or to couple several tanks with unfailing reliability. Whether you are working on a sprinkler network or an industrial system, brass ensures an exceptional longevity of your water recovery equipment.
Invest in quality: install a brass overflow and secure your IBC tank
A “1/2 inch” thread measures 20.96 mm, not 12.7: in plumbing, the inch size is not converted, it is read from a chart. Here you will find the inch / mm correspondence of every common thread (BSP or “gas thread”, French names 15/21 · 20/27 · 26/34, NPT, S60x6 IBC tanks, Guillemin, Camlock, PVC), a tool that identifies your thread and the fitting that goes with it, and the pitfalls to avoid.
No need to know the name of your thread. Tell us what you need to connect to, or type what you know (“20/27”, “3/4 inch”, “S60x6”, “26.4 mm”): we identify the thread and show you the fittings that go with it. Dimensions according to ISO 228, ISO 7 and ASME B1.20.1.
No need to know the name of your thread. Just answer the question: what do you need to connect to?
With a caliper, measure the outside diameter of a male (thread visible on the outside) or the inside diameter of a female (thread inside the hole), at the root of the thread.
