Fernco Inc PQT-400 Flexible Sanitary Tee 4x4x4 in

Product Description

The FERNCO INC PQT-400 is a flexible sanitary tee fitting designed for drain, waste, and vent (DWV) piping systems. Constructed from PVC with flexible coupling technology, it connects branch drain lines to main stacks without requiring rigid pipe alignment. The fitting measures 4 inches by 4 inches by 4 inches and accommodates the slight misalignments and pipe movement common in residential and light commercial plumbing. Licensed plumbers and experienced pipe fitters install this type of fitting when making DWV connections in new construction or repair work where rigid fittings are impractical.

The PQT-400 is suited for residential and light commercial DWV applications where a sanitary tee configuration is needed at a 4-inch main with a 4-inch branch inlet. Its flexible design accepts cast iron, steel, plastic, copper, and lead pipe materials, making it a practical choice for renovation and repair projects where the existing pipe material may vary. The fitting is sold in packages of 5 units, useful for larger jobs requiring multiple connections at the same pipe size.

Installation Notes

Installation should be 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 dry before beginning work. Follow the manufacturer torque guidelines on stainless clamps to achieve a proper seal without over-compressing the flexible sleeve. Verify that the branch inlet is oriented correctly in the direction of flow as required for sanitary tee fittings in DWV systems.
