Pentair Air Bleed Sock Kit

The Pentair Air Bleed Sock Kit (part number 190106Z or 190106) is a specialized internal utility package designed for various Pentair cartridge and D.E. filtration systems, including the Clean & Clear Plus, FNS Plus, and Quad D.E. series. This kit features a fine, mesh-fabric filter sleeve (or "sock") that slides directly over the top of the internal automatic air relief tube assembly. Its primary structural and operational role is to act as a porous mechanical shield that continuously filters out fine debris, organic matter, and diatomaceous earth powder before it can enter the narrow air relief line. By permitting trapped air to bleed out freely while blocking particles from clogging the small air-venting orifice, the kit ensures that the filtration system can automatically exhaust dangerous air pockets without manual intervention. Fabricated from a high-tensile, chemical-resistant polymer mesh that withstands continuous underwater turbulence, shifting internal manifold pressure, and high concentrations of pool sanitizers like chlorine, this maintenance kit prevents premature wear on internal venting hardware. Because it is comprised of ultra-lightweight fabric and a plastic securing tie, the entire air bleed sock kit carries a nominal product and shipping weight of approximately 0.05 pounds (about 0.8 ounces).
