Parker 9933-11-BQ Inline Disposable Gas Liquid Filter

Product Description

The PARKER 9933-11-BQ is a disposable inline filter designed to remove contaminants from gas or liquid lines in compressed air and fluid system applications. Built with a nylon body, it accepts 0.25-inch tube end connections and is rated for a maximum operating pressure of 125 psi. The filter delivers up to 7.3 CFM of flow capacity and provides fine filtration at a 0.01 micron rating, making it suitable for protecting downstream regulators, lubricators, valves, and instrumentation from particulate contamination. At 4.5 inches in length, it fits easily into tight inline installations. Licensed technicians and pipefitters working on compressed air, pneumatic control, or fluid handling systems will find this a straightforward, replace-and-discard solution.

This filter is well suited for residential and light commercial pneumatic systems, inline protection of regulators and lubricators, and fluid line filtration in instrumentation and process control applications. The tube-style end connections allow for direct integration into existing 0.25-inch tubing runs without additional fittings in many installations. It is a disposable unit, meaning no element replacement or bowl cleaning is required — the entire assembly is swapped out at end of service life.

Key Features

• Disposable design eliminates bowl cleaning and element replacement
• 0.01 micron filtration rating for fine particulate removal from gas or liquid media
• 0.25-inch tube end connections for direct inline installation
• 125 psi maximum operating pressure
• 7.3 CFM flow capacity
• Compact 4.5-inch overall length for space-constrained installations

Compatibility

Designed as an OEM-style inline disposable filter for use in 0.25-inch compressed air, pneumatic control, or fluid handling lines requiring fine particulate filtration ahead of regulators, lubricators, or sensitive instrumentation.

Installation Notes

Installation should be performed by a qualified technician or pipefitter familiar with compressed air or fluid system service. Depressurize and isolate the line completely before removing the existing filter or making any connections. Verify flow direction marked on the filter body before installing, and confirm all tube fittings are fully seated and leak-free before returning the system to service. Consult applicable codes and the equipment manufacturer's documentation for system-specific requirements.
