Pro-source 121370170 Sewer Nozzle 4200 Psi Fixed Stainless

Product Description

The PRO-SOURCE 121370170 is a fixed sewer pressure washer nozzle rated to 4,200 psi, constructed from polished stainless steel for corrosion resistance in wet, high-pressure environments. The nozzle features a 4.5mm orifice diameter and a 1/4-inch female pipe thread (FPT) connection. It is designed for sewer jetting applications where consistent flow direction and a permanent spray pattern are required. Plumbers, drain cleaning technicians, and municipal maintenance crews install this type of nozzle when clearing grease, debris, and scale buildup from drain lines and sewer laterals using trailer-mounted or portable jetter units.

This nozzle is suited for residential and light commercial sewer jetting work. The fixed nozzle style delivers a set spray pattern without adjustable rotation, making it appropriate for straight-run drain cleaning passes and applications where a stable, non-rotating jet profile is preferred. The 1/4-inch FPT thread is a standard connection size found on most sewer jetter hose assemblies and quick-connect adapters used in the drain cleaning trade.

Key Features

• Rated to 4,200 psi maximum working pressure for high-demand jetting applications

Compatibility

Designed as an OEM-style replacement or upgrade nozzle for sewer jetter systems equipped with a 1/4-inch FPT hose connection and rated to handle up to 4,200 psi operating pressure.

Installation Notes

Installation is typically performed by licensed plumbers or drain cleaning technicians. Relieve all pressure from the jetter system and shut off the pump before removing or installing any nozzle. Use appropriate thread sealant compatible with high-pressure water service on the FPT connection. Inspect the orifice and thread condition before each use to ensure safe operation at rated pressure.
