Water Filtration & Sanitation Systems

Engineered Plastics for Chemical Resistance, Pressure Tolerance, and Regulatory Compliance

From municipal treatment plants to high-pressure RO systems, CDS Plastics delivers precision-machined plastic parts that stand up to chemicals, pressure, and nonstop operation. We help water filtration and sanitation systems run reliably, meet safety standards, and minimize costly downtime.

Benefits of Using Plastics in Water Filtration & Sanitation Applications

When water systems face constant exposure to moisture, chemicals, and sanitation protocols, traditional materials like metal often fall short. High-performance plastics offer clear advantages, from reduced corrosion to simplified maintenance.

Corrosion Resistance: Plastics hold up where metals corrode, especially in systems exposed to chlorines, salts, and aggressive chemicals.

Meets Regulatory Standards: FDA and NSF-compliant materials support safe potable water handling and hygiene-critical applications.

Lower Maintenance Needs: Plastics are lightweight and wear-resistant, making them easier to install and less prone to fatigue.

Excellent Chemical Compatibility: Withstand harsh acids, alkalis, and disinfectants used in treatment systems.

Design Versatility: Easily machined to meet OEM specs, retrofit parts, or complex geometries that metal can't match.

Plastic Materials Used in Water Filtration Systems

The materials listed below are selected for their proven performance in water filtration and sanitation systems. Each offers a balance of chemical resistance, dimensional stability, and hygiene compliance, making them well-suited for components exposed to continuous moisture, pressure, and corrosive cleaning agents. These plastics support safe water handling and long-term system reliability.

Material	Key Properties	Common Applications
Acetal (Delrin®)	FDA-compliant, low moisture absorption, dimensional stability	Valve components, filter housings, seals, manifolds
UHMW-PE	Wear-resistant, low friction, FDA-compliant	Scraper blades, guides, conveyor wear parts
Polypropylene	Lightweight, chemical-resistant, cost-effective	Tank components, pipe fittings, plumbing interfaces
PTFE (Teflon®)	Exceptional chemical resistance, non-stick, FDA-approved	Gaskets, valve seats, diaphragm housings
PVC / CPVC	High chemical resistance, durable, widely used in fluid handling	Pipe fittings, tank components, valve housings, connectors

Frequently Asked Questions

We’re not just a plastics machine shop — we’re a responsive, engineering-driven partner. From compliance-critical parts to emergency replacements, CDS Plastics delivers dependable results that keep water systems running clean, safe, and uninterrupted.

Which plastics are best for water filtration components?

Acetal, PTFE, UHMW, Polypropylene, PVC and CPVC are commonly used due to their chemical resistance and engineering properties.

Can you machine parts for pressurized RO systems?

Yes. We regularly machine housings, seals, and custom assemblies designed for high-pressure RO and desalination units, ensuring durability and dimensional accuracy.

Why choose plastic over stainless steel in water systems?

Plastics offer superior corrosion resistance, are lighter, easier to machine, and are ideal for chemical-heavy or hygienic environments where metal degrades over time.

Do you offer reverse engineering for legacy or worn components?

Absolutely. We can replicate, refine, or redesign worn or undocumented plastic parts — even without technical drawings — using modern materials for better performance.
