Technical Data
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.
Key specifications:
- Filtration: 40 micron standard (TB-05); 10 micron standard (all others); 3 micron available (TB-25)
- Thread options: BSPP and NPT standard; UNF threads available
- Standard thread size: 1/4" BSPP (TB-05) through to 2-1/2" BSPP (TB-165)
- Housing: Aluminium (TB-05, TB-25); Nylon (TB-35, TB-65, TB-165)
- Optional pressurised version (P): maintains 5 psi, built-in release valve, filtered exhaust
- Optional splash guard (SG)
- Optional dip stick: 4", 6", or 8"
- Optional black powder coated cap (B)
