Parker 9933-05-BQ Inline Filter 0.25 Inch Tube Connection

Product Description

The PARKER 9933-05-BQ is a disposable inline filter designed for use in compressed air and fluid systems where contamination control is critical. Rated for flow up to 6.6 CFM with a maximum operating pressure of 125 psi, this filter targets particulates down to 0.01 microns. The nylon body keeps weight low while providing resistance to a range of gases and liquids. It installs in-line on tube connections at a 0.25-inch pipe size and is serviced by replacement rather than element cleaning, making it well suited for high-turnover maintenance programs. HVAC technicians, refrigeration technicians, and plumbers install this type of filter to protect downstream regulators, valves, and instrumentation from contaminants.

This filter is appropriate for residential and light commercial compressed air lines, pneumatic control circuits, and gas or liquid service applications where a compact, low-profile filtration point is needed. The 0.25-inch tube-end connection fits standard small-bore pneumatic and fluid tubing configurations. At 3.25 inches in length, it fits in confined spaces common to equipment cabinets and mechanical enclosures. The disposable design eliminates element-cleaning steps and reduces service time during routine maintenance visits.

Installation Notes

Installation should be performed by a qualified technician after depressurizing and isolating the affected line. Ensure the system is fully vented to zero pressure before disconnecting any fittings. Observe flow-direction markings on the filter body during installation. Follow all applicable codes for pneumatic or fluid system work, and verify tube fitting connections are fully seated and leak-free before returning the system to service.
