Material Selection

Three Materials — One System

All ERECTA SWITCH components are available in three chemically-resistant thermoplastics. Select the material that matches your fluid chemistry.

PP — Polypropylene

General Purpose · Gray Body

Water, soaps, coolants, dilute acids, and alkaline cleaning solutions. The standard specification for aqueous applications. Lowest cost per unit.

AC — Acetal

Hydrocarbons · Red Body

Gasoline, diesel, hydraulic oil, motor oil, kerosene, and petroleum-based fluids. The correct specification when polypropylene is incompatible with the fluid chemistry.

KR — Kynar PVDF

Aggressive Chemicals · Natural Body

Concentrated acids, caustics, oxidizers, halogens, and high-purity process fluids. Maximum chemical resistance for semiconductor, electroplating, and chemical processing applications.

Why Buy Components

Field Service & OEM Flexibility

ERECTA SWITCH components give engineers and maintenance teams complete control over sensor configurations.

Field Replacement

Replace a single damaged float or worn O-ring without removing the entire switch assembly. Every component threads on and off by hand — no special tools required.

Custom Configurations

Build application-specific sensor assemblies from stock parts. Combine switching elements, precision nipples, receptacles, and fittings to match any tank geometry.

OEM Integration

Purchase individual components for integration into your own equipment designs. Consistent dimensions and threads across all materials simplify mechanical design.

Frequently Asked Questions

Common Questions About This Product

What liquid chemistries is the ERECTA SWITCH component compatible with?

Choose the material to match the media: Polypropylene (PP) for general aqueous, acids, and bases; Acetal (AC/Delrin) for solvents, fuels, and hydrocarbons; Kynar PVDF (KR) for aggressive or harsh chemicals. Every ERECTA SWITCH model is offered in all three materials.

What factors should I consider when choosing the ERECTA SWITCH component?

Consider media chemistry (pick PP, AC, or KR), liquid specific gravity, operating temperature and pressure, mounting style, number of switch points, and electrical contact rating. Compac will spec it from your application — request a free evaluation sample.

What makes ERECTA SWITCH different from other level switches?

It is the only fully modular, off-the-shelf liquid level switch system: switch, float, connector, fitting, and nipple are independently field-replaceable and stocked. OEMs configure exactly what they need with no minimums and short lead times. Made in Paradise, California; RoHS compliant.

Can I order individual ERECTA SWITCH replacement components?

Yes. The ERECTA SWITCH component is available as an individual, stocked part — no need to replace the entire switch assembly. ERECTA SWITCH is a fully modular system: switch, float, connector, fitting, spacer, and nipple are all orderable separately with no minimums. This reduces repair cost and downtime for OEM field service.

Are ERECTA SWITCH components interchangeable across models?

Yes — modularity is the core of the ERECTA SWITCH system. The ERECTA SWITCH component is designed to work across multiple Series 10 configurations. Floats, connectors, spacers, and fittings share standard interfaces, so one stocked component serves many switch assemblies. Check the model number to confirm compatibility.

How do I identify which ERECTA SWITCH component I need?

Each component has a unique model number (e.g., ERECTA SWITCH component) that identifies its type, material, and function within the assembly. Contact Compac with your switch model number and the part you need to replace — or request a free evaluation sample to confirm fit before ordering production quantities.
