Why Choose Sock™ For Your Infrastructure Project

Sizes:

Our 100% polyester Sock ™ filters are available to fit pipe diameters ranging from 2″ to 48″ (50 mm to 1200 mm) and are designed to work with all perforated drainage pipes, including corrugated HDPE, steel, aluminum, and PVC pipes.

Our most popular Sock™ is the 4″ filter, which comes in Regular and XL sizes. The 4″ XL filter, while designed for 4″ diameter pipes, is slightly larger in size than the regular 4” filter, making it easier to apply and as a result is less susceptible to damage during normal handling and installation.

Colors:

Most Sock™ filters are available as either white or black fabric. Black fabrics provide enhanced resistance to degradation from UV radiation, in the event of prolonged outdoor storage prior to installation.

Opening Size:
The opening size of our Sock™ filters was designed to prevent sand and soil from entering and clogging agricultural drainage pipes. With an Apparent Opening Size (AOS) of 0.600 mm, or a Filtration Opening Size (FOS) of 450 µm, our Sock™ filters provide the appropriate level of filtration for the vast majority of soils encountered in agriculture. However, in geographies where very fine, sandy, or silty soils are present, filter envelopes with a smaller opening size may be needed. Our Super Sock™ filters are available with an AOS of 0.425 mm, 0.300 mm, 0.250 mm, and 0.150 mm (FOS of 330 µm, 250 µm, 150 µm, and 120 µm) and have been used in agricultural drainage systems as an extra level of protection against very fine soils.   Download our performance data guides for Sock™ and Super Sock™ filters here.
