Description

The Suttner Chemical Injector 999000021 is a high-quality ST-64 upstream chemical injector designed for precise chemical application before the pump in pressure washer systems. Engineered for flow rates between 4.0 and 7.0 GPM, this injector is ideal for introducing detergents, degreasers, or sanitation chemicals into the water stream at low pressure, ensuring pump protection and optimal dilution.

Built with durable components and a flow-optimized body, the ST-64 delivers consistent chemical draw and performance. It is specifically designed for garden hose–style connections, featuring a 3/4" Female Garden Hose (FGH) inlet and a 3/4" Male Garden Hose (MGH) outlet, making it compatible with standard residential and commercial water supply systems.

Applications:

  • Upstream chemical injection for pressure washers

  • Industrial sanitation and cleaning systems

  • Agricultural and horticultural chemical spraying

  • Pre-pump detergent and degreaser application

Features:

  • Upstream injection design protects the pump from chemical exposure

  • Rated for flow between 4.0–7.0 GPM

  • 3/4" garden hose FGH inlet and MGH outlet for easy hose integration

  • Durable construction for reliable long-term use

  • Ideal for downstream equipment that cannot tolerate chemical contact
