The 9-inch and 12-inch diameter diffusers employ a 3/4-inch diameter NPT (male) threaded connection for ease of installation/maintenance and universal application. Units can be mounted using the universal diffuser mount and are also available with Saddle Mount configuration (as shown), which provides unmatched mechanical strength.

Replacement parts are available for the fine bubble disc and tube type diffusers.
