The membrane has an integral O-ring seal which is tightly compressed by our retaining ring which keeps water out and air inside. We make our base and retaining ring from polypropylene. While PP is more difficult to mold PVC, the advantages of higher temperature resistance and greater ductility are worth it. Also, we add organic stabilizers to protect out diffusers from harmful UV rays. Upgrading to the SSI Airflex TM diffuser's performance and quality is easy since our membranes are a standard size and our prices are competitive.
