Oatey Company 42757 Pvc P-trap 3/4 Inch Schedule 40

Product Description

The OATEY COMPANY 42757 is a 3/4-inch Schedule 40 PVC P-trap engineered for full-flow condensate drainage in HVAC and plumbing applications. Built to Schedule 40 wall thickness, it provides the structural integrity needed for reliable service in both new construction and replacement installs. The trap is carefully sized to maintain proper condensate flow without restriction, helping prevent standing water, odor migration, and drain line backups. HVAC technicians and plumbers install this trap as part of condensate drain assemblies on air handlers, furnaces, and fan coil units. Its PVC construction resists corrosion and is compatible with standard solvent-weld fittings.

This P-trap is suited for residential and light commercial HVAC condensate drain lines where a 3/4-inch Schedule 40 PVC connection is required. It is a practical fit for air handler drain pans, fan coil units, and other cooling equipment that generates condensate. The full-flow design minimizes restriction through the trap body, which is important in low-slope or gravity-fed drain configurations. HVAC installers and plumbers working on new equipment installations or service replacements will find this a direct-fit solution for standard 3/4-inch PVC drain assemblies.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and IFGC guidelines. Shut off and lock out the HVAC unit before working on the condensate drain assembly. Use approved PVC solvent cement and primer when joining this trap to existing drain piping, and allow full cure time before restoring system operation. Do not use heat guns or open flame near PVC components during installation.
