Tube Diffusers and Tube Accessories

SSI produces quality tube diffusers for round and square pipes. Save time and money on pipe fabrication and installation labor, choose round, plastic pipe with a saddle connection like our Super Saddle design, available in nominal 4" (110mm) and 6" (150mm) sizes. We say "nominal" because we produce a variety of sizes of gaskets and O-rings to be enable us to fit both metric and US dimensioned pipes.

Stainless Steel Pipes

For the best piping system longevity, choose either square or round stainless steel pipes. For square pipe installations, we offer a variety of gaskets and double-ended nipples to fit our diffusers to 80 x 80mm, 100 x 100 or 120 x 120 square or rectangular shaped pipes.

The new Quick Connector enables connection to square pipe without the use of a double-ended nipple This is both cost effective, reduces the headloss created by the double nipples in small square pipes, and it is easier for divers to work with in case of a wet diffuser replacement. For round stainless pipe installations, we offer simple threaded nipples.

Tube Diffusers

All of these configurations are available for both nominal 2.5" (65mm) and 3.7" (94mm) diameter tube diffusers in lengths to 40" (1000mm).
