10-792-PP — Polypropylene Bulkhead

SKU: 10-792-PP  ·  Stock #5501342  ·  1-Pack · Single Unit
Polypropylene · 1-Pack

When your tank is plastic, fiberglass, or sheet metal and you need a leak-proof vertical level switch without drilling and tapping an NPT thread, the 10-792-PP solves it cleanly. The 10-702-BH bulkhead fitting seals directly into a smooth hole with a dual O-ring face seal — no thread cutting, no sealant tape, no risk of cross-threading. The polypropylene construction handles water, water-soluble coolants, soaps, detergents, and dilute acid solutions without degradation. The float is field-reversible — flip it to switch between normally open and normally closed operation without changing part numbers.

What Makes the 10-792-PP the Right Choice

O-ring sealed bulkhead mount
10-702-BH fitting seals into a smooth drilled hole — no NPT tapping, dual O-ring face seal eliminates leak paths
1/4″ NPT above-deck connection
Above-deck wiring exits through 1/4″ NPT for conduit or strain relief
Field-reversible float
NO or NC by float orientation — no separate part numbers
Polypropylene construction
Water, coolants, soaps, light acids, and dilute alkaline solutions
Field-replaceable core
10-782-PP switching element swappable without removing the bulkhead fitting
Lower above-deck profile
0.75″ above deck vs. 0.875″ on bare 10-782 — more clearance for tight lids

Frequently Asked Questions

Common Questions About This Product

What is the difference between a float level switch and a liquid level sensor?

A float level switch like the 10-792-PP is a point-level device: a float rides the liquid and actuates a magnetic reed switch at a set height, giving a simple on/off signal — no power, no firmware, no calibration. "Sensors" usually means continuous measurement (ultrasonic, radar, capacitive). ERECTA SWITCH targets reliable discrete-point control.

What factors should I consider when choosing the 10-792-PP?

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 liquid chemistries is the 10-792-PP 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. Most ERECTA SWITCH models are offered in all three materials; some are material-specific, so check the product page for the model you need.

What mounting options are available for the 10-792-PP?

ERECTA SWITCH offers vertical top-mount, bulkhead, and extended-stem configurations, plus side-mounted single-point models. The mount style is part of the model number — select the configuration that matches your tank geometry.

How is the actuation level set on the 10-792-PP, and how accurate is it?

Point detection is repeatable and mechanical. The trip height on the 10-792-PP is set by the 10-715 Precision Nipple, ordered separately in 1-inch increments (1″–70″), so you place the switch point exactly where the application needs it.

What pressure and temperature can the 10-792-PP handle?

It depends on the series, and the derate matters more than the headline. Series 10 is rated 100 PSI, Series 15 50 PSI and Series 20 20 PSI — each at 20°C, each derating to zero at 90°C, so a hot line has no pressure allowance left. Series 20 sits lowest by design: its float sections are thin-walled, and sustained pressure can crush them. Temperature follows the material — on Series 10, PP: 180°F, AC: 200°F, KR: 280°F.

Can one 10-792-PP switch control both a high and a low level?

A single switch detects one point. For high-plus-low detection (or more), use a multi-level extended-stem set that places multiple reed points on one stem, giving you independent high and low signals from a single mounting hole.

How do I wire the 10-792-PP to a pump or alarm?

The 10-792-PP uses a magnetic reed switch wired in series with your relay or controller. Contact rating is 70 VA / 50 W resistive (UL File E70063). The switch ships with lead wires — connect directly to your control circuit.

Does the 10-792-PP need calibration?

No. The 10-792-PP is a mechanical float actuating a sealed reed switch — there is nothing to calibrate or power. This is a reliability advantage over electronic sensors that can drift over time.

How do I maintain the 10-792-PP, and what if it stops working?

Inspect that the float moves freely (check for debris or scaling), then test reed continuity with a multimeter. Because ERECTA SWITCH is modular, you replace only the individual component — switch, float, connector, or fitting — instead of the whole assembly.

Is the 10-792-PP safe for flammable or hazardous-area liquids?

Standard ERECTA SWITCH models are not rated for hazardous (Class I / Div) areas. For flammable-service applications, contact Compac engineering to discuss your requirements and available options.

What are the typical applications for the 10-792-PP?

The 10-792-PP is used for pump start/stop control, high-level overflow protection, low-level dry-run protection, and tank or reservoir level alarms in OEM equipment. The modular ERECTA SWITCH system is built into laundry, HVAC, water-treatment, hydraulic, and chemical-handling machinery.

What makes ERECTA SWITCH different from other 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.
