I would like to commend Ozone Solutions for their quality workmanship and superior customer service. Ozone Solutions provided us with a well-designed ozone sparge system with plenty of room inside to move around and perform the operation and maintenance on the ozone system. You were extremely helpful during the engineering, planning, and building process...

PT-12: Porous PTFE Diffuser

Bendable porous design accommodates a wide variety of setups


  • Flexible
  • Non-stick surface prevents clogging
  • Outstanding ozone/chemical resistance
  • Durable

(See Full Specifications)

PT-12 $21.95
Stock: In Stock
PT-12 (12 inches of porous tubing - straight length)
PT-12-circle $27.95
Stock: In Stock
PT-12 (12 inches of porous tubing assembled into a 4 inch diameter circle with a 12" non-porous riser stem)
PT-12 raw tubing $9.95
Stock: In Stock
Inform us if you want this additional length (sold per foot) connected to the 12 inches of either product listed above. Otherwise, this product will be shipped loose.


This diffuser is ideal for dirty environments, due to it's non-stick PTFE construction. It will give you years of life with very little, if any, cleaning requirements. Customizable lengths are available.

What makes the PT-12 different?

The porous PTFE tubing complies with FDA Regulation 21 CFR 177.1550, which is a food grade certification.

To help overcome the PSI requirement, to achieve the desired flow rate, you can either increase the length of the porous tube, or distribute into multiple PT-12's.
NOTE-If immersed in water, every foot of water depth requires an additional 0.43 PSI. Other fluids might be different.
