Abstract: Devices and methods for protecting pipe vents from clogging due to foreign matter or creatures are disclosed herein. In one aspect, the invention provides a fitting for use with a pipe vent that includes a cylindrical ring-shaped member having an inner lumen extending therethrough between first and second open ends, an outer sidewall defining an outer diameter, and an inner sidewall defining an inner diameter. The invention further includes a mesh screen fixedly mated to the inner sidewall of the ring-shaped member such that the mesh screen extends across the entire inner lumen to prevent large particle debris from passing through the inner lumen. The ring-shaped member can also include a groove formed in an outer surface thereof to permit liquid drainage.
