Mini Disposable Air Line Desiccant Filter 1/4 NPT 125 PSI is a compact air line component that conditions compressed air where space is tight. The unit is described as a 1/4 inch NPT mini precision lubricator with a visible drip type design and an external adjustment screw, so technicians can see and set lubrication as air flows. It is designed for low air flow applications where available space is limited, matching small tools or point-of-use drops. A bypass system allows full air flow with minimum pressure drop, keeping connected equipment supplied while the air is treated. The same bypass design assures a proper air and water mixture over the full operating range, supporting consistent process results wherever it is installed.
The unit uses 1/4 inch male and female national pipe threads, so it can be threaded inline where that size is used in the system. It requires approximately 1 standard cubic foot per minute of air flow to deliver oil, so it starts functioning at modest flow rates often seen with smaller tools. A maximum flow capacity of 15 standard cubic feet per minute defines the operating range, which helps match the component to air circuits of similar demand. The maximum pressure rating of 125 pounds per square inch sets the upper system pressure under which the filter is described to operate. A working temperature span from 32 degrees Fahrenheit to 130 degrees Fahrenheit places the component within typical indoor shop air environments.
This Milton Industries mini precision lubricator sits within the air line as part of a filter/regulator/lubricator setup, supporting air line components where space is limited. The 1/4 inch NPT male and female threads position the unit between existing fittings of that size, so it naturally suits light air circuits using 1/4 inch connections. Design for low air flow applications ties it to smaller drops and stations where individual tools or devices need conditioned air without adding large housings. The 15 standard cubic feet per minute maximum flow capacity aligns with this role, matching air usage typical of compact pneumatic tools, blow-off points, or control devices that do not demand very high volume.
The working temperature range from 32 degrees Fahrenheit to 130 degrees Fahrenheit links the unit to indoor or sheltered locations where compressed air systems commonly operate. A maximum pressure rating of 125 pounds per square inch matches many shop air systems that run below that value, so this component can be placed in those environments when pressure aligns with the rating. The polycarbonate bowl gives visibility to what is occurring inside the unit at a glance, helping users understand air conditions where the filter is installed. Together, these characteristics define a compact, targeted role for air line conditioning in constrained spaces.
The visible drip type design provides a direct view of lubricant passing through, which helps users relate tool performance to observed drip rate. An external adjustment screw on the mini precision lubricator allows changes to lubrication delivery to be made from the outside, connecting system behavior to a simple mechanical control. The requirement for approximately 1 standard cubic foot per minute of air flow to deliver oil shows that even modest movement of air will generate lubrication, which suits intermittent-use tools that do not constantly draw high flow.
The bypass system described for this unit allows full air flow with minimum pressure drop, which helps keep tools responsive while still benefiting from air treatment. That same bypass arrangement assures a proper air and water mixture over the full operating range, supporting predictable process outcomes when air quality and mixture are important. Located in the Filters, Regulators, Lubricators product class, this component functions within broader air preparation assemblies, helping align lubrication and flow behavior across the system. When matched to circuits within its 15 SCFM and 125 PSI ratings, the unit contributes to stable air delivery tailored to compact installations.
The Milton Industries S-1173 unit is described as a 1/4 inch NPT mini precision lubricator within the Filters, Regulators, Lubricators product class, so it serves as a compact air line conditioning component.
The visible drip design shows lubricant passing through the mini precision lubricator, helping users relate tool behavior to observed drip rate and adjust the external screw accordingly.
The product has 1/4 inch male and female national pipe threads, allowing it to be threaded inline where 1/4 inch NPT connections are present in the air system.
The mini precision lubricator requires approximately 1 SCFM to deliver oil and has a maximum flow capacity of 15 standard cubic feet per minute, matching low air flow applications.
The unit is described with a maximum pressure of 125 pounds per square inch and a working temperature range from 32 degrees Fahrenheit to 130 degrees Fahrenheit for defined operating conditions.
The bypass system allows full air flow with minimum pressure drop and assures a proper air and water mixture over the full operating range, supporting consistent downstream air behavior.
This Milton Industries 1/4 inch NPT mini precision lubricator combines a visible drip type design, external adjustment screw, and a polycarbonate bowl into a compact format for low air flow locations. Its 15 SCFM maximum flow capacity, 125 PSI maximum pressure, and 32 to 130 degrees Fahrenheit working temperature range define where it fits within shop air circuits. For air lines built around 1/4 inch NPT connections that need conditioning in constrained spaces, this mini unit provides defined flow, temperature, and pressure characteristics that support targeted installation decisions.
