The FERNCO INC PQL-300 is a 3-inch Qwik Elbow fitting designed for fast, flexible pipe connections in drain, waste, and vent (DWV) plumbing systems. This elbow coupling allows plumbers and pipefitters to make directional changes in piping runs without solvent welding or mechanical fasteners, relying instead on a flexible sleeve design that conforms to pipe ends for a secure seal. Packaged in units of 10, the PQL-300 is suited for both new installation and repair work where quick access or limited workspace makes rigid fittings impractical.
The PQL-300 is used in residential and light commercial plumbing applications where 3-inch DWV piping requires a change in direction. Typical install scenarios include drain line repairs, stack connections, and retrofits in tight spaces such as crawlspaces, wall cavities, or beneath slabs. The fitting is sold as a single unit (each) and is packaged in quantities of 10, making it practical for contractors stocking multiple units per job.
Designed as an OEM-style replacement and installation fitting for 3-inch DWV piping systems common in residential and light commercial plumbing.
Installation is typically performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off water supply and ensure the drain line is depressurized and cleared before beginning work. Clean pipe ends thoroughly before seating the fitting to ensure a proper seal. Follow the manufacturer torque or clamp guidance printed on the fitting packaging.
