Washer reservoir caps for trucks and commercial vehicles

Washer reservoir caps play an important role in the proper operation of the windshield washer system in trucks and commercial vehicles. They ensure tight sealing of the washer fluid reservoir, protecting the fluid from leakage, evaporation, and contamination.

Sealing and protection of the washer system

A damaged or loose reservoir cap may lead to washer fluid loss and malfunction of the entire system. When combined with properly selected washer reservoirs, reliable washer pumps, and precise washer nozzles, reservoir caps ensure full system tightness and dependable performance.
