Product Overview

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.


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