Lesso UV429-010 Sch 40 Pvc Coupling 1 Inch Sxs

Product Description

The LESSO UV429-010 is a 1-inch Schedule 40 PVC coupling rated for UV resistance, designed for solvent-weld socket-by-socket (SxS) connections. It joins two lengths of 1-inch Schedule 40 PVC pipe in a straight run, creating a pressure-rated, leak-resistant joint when installed with the correct primer and solvent cement. At 0.08 pounds, the fitting is lightweight and easy to handle in tight spaces. UV-resistant formulation makes it suitable for exposed outdoor runs where standard PVC would degrade under prolonged sun exposure. Licensed plumbers and irrigation installers are the primary trades that specify this fitting.

This coupling is appropriate for residential and light commercial plumbing, irrigation, and pool and spa piping systems where 1-inch Schedule 40 PVC is the specified pipe material. Its UV-resistant construction makes it a practical choice for above-ground outdoor installations such as exposed irrigation headers, pool equipment pads, and utility service lines that see direct sunlight. It is not intended for hot-water or CPVC systems.

Key Features

• UV-resistant PVC formulation suitable for exposed outdoor installations
• Schedule 40 wall thickness for standard pressure-rated piping systems
• Socket-by-socket (SxS) ends accept solvent-weld connections
• 1-inch nominal pipe size for common residential and light commercial runs
• Lightweight at 0.08 pounds for easy single-hand positioning during glue-up

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch Schedule 40 PVC piping systems using solvent-weld joints.

Installation Notes

Installation is performed by licensed plumbers or qualified irrigation technicians following applicable IPC and local plumbing code requirements. Shut off and depressurize the supply line before cutting into any existing piping. Clean and dry both pipe ends, apply PVC primer to both the pipe and socket, then apply solvent cement and seat the pipe fully with a quarter-turn twist. Allow adequate cure time per the cement manufacturer instructions before restoring pressure.
