Parker 4433-05-BQ Inline Filter 1/4 Inch 125 Psi

Product Description

The PARKER 4433-05-BQ is a disposable inline filter designed for use in compressed air, gas, and liquid lines requiring reliable particulate removal at working pressures up to 125 psi. Built with a nylon body, it handles a flow rate of 6.6 CFM and connects via 1/4 inch tube end connections. At 3.5 inches in length, it fits easily into tight inline installations. This filter is commonly installed by HVAC technicians, pneumatic system installers, and fluid-handling trades as a low-cost, replace-on-interval filtration component that does not require service or cleaning.

This inline filter is suited for light industrial and commercial pneumatic systems, compressed air distribution lines, and gas or liquid filtration applications where disposable elements are preferred over serviceable housings. Its 0.01 micron rating provides fine filtration performance appropriate for protecting downstream instrumentation, regulators, and control components. The compact form factor allows installation in space-constrained panels, cabinets, or inline runs without additional mounting hardware in many applications.

Key Features

• Disposable design rated for gas or liquid service eliminates element servicing
• 0.01 micron filtration rating protects sensitive downstream components
• 1/4 inch tube end connections for direct inline installation
• 125 psi maximum working pressure
• 6.6 CFM flow capacity suits light industrial pneumatic lines
• Nylon body construction for lightweight, corrosion-resistant performance

Compatibility

Designed as an OEM-style inline filter for compressed air, gas, and liquid distribution systems using 1/4 inch tube connections and operating at pressures up to 125 psi.

Installation Notes

Installation is typically performed by a licensed HVAC technician, pipefitter, or pneumatic systems technician. Always isolate and depressurize the line before removing the existing filter or installing a new unit. Verify flow direction markings on the filter body and ensure tube fittings are fully seated to prevent leaks. Follow applicable codes, including ASME and local compressed air system guidelines, when integrating filtration components into pressurized lines.
