Drain stopper Rittal 3286780 — trip lever, black polypropylene, Ø 8 cm

The Rittal 3286780 drain stopper is a lever-operated sealing component made of black polypropylene with a diameter of 8 cm, designed to regulate drainage in electrical enclosures and equipment housings. It provides a mechanical opening and closing action via a trip lever, offering a straightforward way to control water discharge from cabinets, rooftop units and other industrial housings where a resilient, chemically resistant seal is required.

Advantages

The polypropylene construction ensures chemical and corrosion resistance while keeping the component lightweight. The trip lever mechanism provides simple, reliable manual operation for opening and closing the drain, reducing the need for tools. Its 8 cm diameter fits standard drainage ports in many enclosures and allows for an effective seal to prevent ingress of contaminants while permitting controlled release of accumulated water.

Suitable for

• Industrial electrical cabinets and control enclosures
• Rooftop units and HVAC housings
• Outdoor enclosures exposed to rain and condensation
• Equipment housings requiring a durable, chemical-resistant drain seal

When it may not be suitable

This drain stopper is intended for manual, lever-operated drainage control and may not be appropriate where automatic or electrically actuated drainage is required. It is designed for typical enclosure drainage applications and may not be suitable for systems requiring high-pressure fluid sealing or where specific regulatory approvals for potable water or food contact are mandatory.

Key specifications

• Material: black polypropylene
• Type of operation: trip lever (manual)
• Diameter: 8 cm
• Typical application: enclosure and rooftop unit drainage
• Resistance: chemical and corrosion resistant typical of polypropylene

How to use

Insert the drain stopper into the enclosure drain port matching the 8 cm diameter opening and engage the trip lever according to the enclosure design. Use the lever to open the seal when draining is required and close it to protect the interior from ingress. Periodically inspect the stopper and surrounding area for debris or damage and clean with a mild, non-abrasive detergent compatible with polypropylene to maintain reliable operation.

What to consider before purchase

• Verify that the drain opening diameter in your enclosure matches the 8 cm stopper size.
• Ensure polypropylene material and manual lever operation meet your environmental and operational requirements.
• Confirm that a manual trip lever is acceptable for your maintenance procedures (no electrical actuation).
• Check compatibility with any chemicals or cleaning agents used in your installation.

Usage recommendations

For reliable performance, install the stopper in a clean, aligned drain port and operate the trip lever gently. Inspect regularly for deposits, and avoid aggressive solvents that could degrade polypropylene. If used outdoors, periodic checks after severe weather will help ensure the seal remains effective.
