The LESSO UV401-015 is a Schedule 40 PVC tee fitting designed for use in pressure piping systems where UV exposure resistance is required. All three ports use a socket (slip) connection style, making this a true SSS configuration. At 1-1/2 inches in size, this tee joins three runs of same-size PVC pipe at a 90-degree branch. It is suited for plumbing, irrigation, and industrial piping applications where solvent-weld connections are the standard joining method. The UV-resistant formulation helps maintain material integrity in above-ground or exposed outdoor installations. Licensed plumbers and irrigation technicians are the primary installers of this fitting type.
This tee is appropriate for residential and light commercial piping systems operating within the rated pressure limits of Schedule 40 PVC. Common applications include cold water distribution, irrigation manifolds, pool and spa plumbing, and chemical handling systems where PVC is chemically compatible. The UV-resistant designation makes it a preferred choice over standard PVC fittings when the piping will be installed above grade and exposed to direct sunlight for extended periods.
Designed as an OEM-style replacement or new-installation fitting compatible with 1-1/2 inch Schedule 40 PVC pipe and solvent-weld fittings per ASTM D2466 standards.
Installation is performed by licensed plumbers or irrigation technicians using standard PVC primer and solvent cement per the fitting and cement manufacturer instructions. Depressurize and drain the line fully before cutting into an existing system. Follow local plumbing code requirements, including IPC guidelines, for allowable pressure ratings and approved joining methods. Do not use this fitting on hot water lines or applications exceeding the pressure-temperature ratings of Schedule 40 PVC.
