O2B2 Linear Diffuser Tubing is purpose-built airline tubing for diffused aeration systems—delivering steady airflow from your compressor to linear diffuser assemblies with a clean, reliable connection.
Designed for linear diffusers: Optimized for feeding air evenly to linear diffuser runs in pond and lake aeration applications.
Efficient air delivery: Smooth internal airflow path helps reduce unnecessary restriction for consistent performance.
Flexible but durable: Built to route cleanly through cabinets, trenches, and shoreline transitions without fighting the install.
Kink- and crush-resistant: Holds shape and protects airflow where standard hose can pinch, flatten, or collapse.
Tough outer jacket: Stands up to wet environments, soil contact, and everyday handling during service and seasonal changes.
Secure connections: Compatible with common aeration fittings/clamps so you can create leak-resistant joints (especially at manifolds and diffuser drops).
Clean, organized plumbing: Helps keep your diffuser layout tidy for easier troubleshooting, future expansions, and maintenance.
Reliable for long runs: Ideal for longer airline distances where durability and consistent airflow matter.
Built for real-world aeration installs: A dependable choice for contractors and property owners who want fewer headaches over time.
Product type: Fine-bubble air diffusion/aeration tubing
Construction: Dual, self-ballasting extruded tubing
Material: Thermoplastic elastomer compound
Diffusion design: Primary tube features a multitude of tiny diffusion holes arranged in a specific pattern to emit and control airflow
Bubble size range: Produces fine bubbles approximately 1/100″ to 1/16″ when pressurized
Inside diameter (ID): 1/2”
Standard roll length: 100 ft
Custom lengths: Available on request (contact us)
Ballast/stability: Self-ballasting design helps the tubing stay positioned during operation
Application: Designed for diffused aeration applications requiring controlled fine-bubble output
Plan your run: Measure compressor-to-waterline distance, then waterline-to-diffuser distance. Add slack for routing and service loops.
Cut cleanly: Use a sharp tubing cutter/utility knife for a square cut (reduces leak risk).
Fit before clamping: Push tubing fully onto the fitting/barb before installing clamps.
Clamp properly: Use stainless gear clamps (or the fitting type you supply) and tighten snug—do not overtighten and deform the tubing.
Protect transitions: At cabinet exits and shoreline edges, use grommets/conduit or abrasion protection where rubbing could occur.
Route for airflow: Avoid sharp bends and pinches. Keep bends gentle to prevent restriction.
If burying: Bed in sand/fine soil where possible, and avoid rocks that can press into the line over time.
Leak check: Run the compressor and check joints with soapy water at all connections before final backfill/closing panels.
Commission: Confirm consistent bubbles across the entire linear diffuser length once deployed.
What is this tubing used for?
This tubing is the airline that carries air from your aeration cabinet/compressor to your O2B2 linear diffuser. It’s a key part of a diffused aeration system: compressor → tubing/airline → diffuser → fine bubbles.
What do I need with it?
Typically:
fittings/manifold connections sized to the tubing ID
clamps (if barbed fittings)
diffuser connection hardware (depending on your diffuser assembly)
optional abrasion protection at transitions (cabinet/shoreline)
