Series 5 accessory fittings in polypropylene for the 9/16-18 UNF ports on all Series 5 flow switches. Four styles: 1/8 NPT female (1/8NPTF), 1/4 NPT female (1/4NPTF), 1/2 NPT male (1/2NPTM), and 1/2 inch hose barb (1/2H). At least one fitting required on every port — the outlet port on 5-21 and 5-21H switches requires a fitting.

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. Most ERECTA SWITCH models are offered in all three materials; some are material-specific, so check the product page for the model you need.
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.
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.
Yes. The 5-XX-PP 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.
Yes — modularity is the core of the ERECTA SWITCH system. The 5-XX-PP 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.
Each component has a unique model number (e.g., 5-XX-PP) 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.
Our engineering team can verify compatibility with your application and chemistry before you order.
