Pro-source ZGUX-2 Frl Manual Drain Polyoxymethylene

Product Description

The PRO-SOURCE ZGUX-2 is a manual drain accessory designed for use with filter-regulator-lubricator (FRL) assemblies in compressed air systems. Made from polyoxymethylene (POM), a high-strength acetal resin, this drain provides reliable manual moisture removal from filter bowls. At 0.02 pounds and compact dimensions of 1.3 inches tall and 0.67 inches wide, it is a lightweight, direct-fit replacement component. Pneumatic technicians and industrial maintenance professionals install this part during routine FRL maintenance or when replacing a failed drain valve on an existing assembly.

This manual drain is compatible with intermediate, standard, compact, and heavy-duty filter bodies in FRL assemblies. It is suited for industrial compressed air lines where manual bowl draining is preferred over automatic drain configurations. Typical applications include manufacturing facilities, production lines, and mechanical rooms where compressed air quality and system uptime are critical. Installation requires no special tooling beyond standard hand tools appropriate for the filter body type.

Key Features

• Polyoxymethylene (POM) construction offers resistance to fuels, solvents, and moisture common in compressed air environments
• Manual drain design gives technicians direct control over bowl draining during maintenance
• Compact form factor at 1.3 inches height and 0.67 inches width for easy integration into existing FRL assemblies
• Lightweight at 0.02 pounds — minimal impact on assembly weight
• Compatible across multiple filter body classes: intermediate, standard, compact, and heavy-duty

Compatibility

Designed for use with intermediate, standard, compact, and heavy-duty filter bodies in FRL assemblies. Verify bowl thread size and drain port configuration against existing hardware before installation.

Installation Notes

Installation should be performed by a qualified pneumatic or industrial maintenance technician. Depressurize and lock out the compressed air supply before removing or replacing any FRL drain component. Hand-tighten the drain into the filter bowl and confirm a leak-free seal before returning the system to service. Do not overtighten POM components, as acetal resin can crack under excessive torque.
