Royal Building Products 35-1604 Pvc Sdr 35 4 in Gasketed 1/16 Bend

Product Description

The ROYAL BUILDING PRODUCTS 35-1604 is a 4-inch PVC SDR 35 gasketed 1/16 bend fitting designed for gravity-flow sewer and drainage piping systems. This low-deflection sweep fitting uses a gasket-joint connection, allowing for faster field assembly without solvent cement on the joint interface. It is manufactured to SDR 35 dimensional standards, which govern wall thickness relative to outside diameter for sewer-grade PVC pipe. Plumbers and underground utility contractors install this fitting during new construction and sewer lateral replacement work.

This fitting is used in residential and light commercial gravity sewer applications, including building drain laterals and municipal tie-in runs. The 1/16 bend provides an 22.5-degree change of direction, making it suitable for gradual alignment corrections in underground drain runs. It is typically installed below grade in direct-bury conditions where the pipe trench is backfilled to ASTM or local municipality compaction specifications.

Key Features

• 4-inch nominal pipe size matches standard SDR 35 sewer pipe outside diameter
• Gasketed bell-and-spigot joint for tool-free, solvent-free field connection
• 1/16 bend (22.5-degree deflection) for gradual directional changes in drain runs
• SDR 35 wall construction rated for gravity sewer service
• PVC material resists corrosion, root intrusion chemicals, and typical sewer gases

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 4-inch SDR 35 PVC sewer pipe systems using gasketed bell-and-spigot joints.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code and applicable local amendments. Verify pipe and fitting surfaces are clean and free of debris before lubricating the gasket and making up the joint. Ensure proper pipe bedding and compaction per local code requirements to prevent joint deflection beyond allowable limits. Do not use this fitting on pressurized water supply or drain-waste-vent systems requiring Schedule 40 or Schedule 80 fittings.
