Hydroline TB Threaded Breather

Hydroline TB Threaded Breather

The TB series threaded breather covers the full range — from compact small-tank installations through to high-flow industrial reservoirs up to 4,000 LPM. Smaller models (TB-05, TB-25) feature aluminium construction; larger models (TB-35, TB-65, TB-165) use a tough nylon housing. All accept a wide range of thread types including BSPP, NPT, and UNF to suit most tank configurations.

Standard filtration is 40 micron on TB-05; all other sizes are 10 micron as standard. A 3-micron option is available on TB-25. An optional pressurised (P) version is available across the range, incorporating a built-in valve that maintains 5 psi in the tank, vents on over-pressure, and filters all displaced air.
