SPEEDAIRE 4ZL74 air compressor lubricator 3/8 in 75 cfm 250 psi
Adds metered oil mist to a 3/8 in air line at up to 75 cfm and 250 psi with an aluminium bowl and sight dome
- Delivers consistent oil mist for tool longevity
- 75 cfm maximum flow supports demanding air lines
- 250 psi operating pressure handles heavy-duty applications
- Aluminium body and bowl resist corrosion in harsh environments
- Sight dome and gauge give instant visual oil-level check
3/8 in NPT air line lubricator
This SPEEDAIRE lubricator introduces a controlled oil mist into a compressed air line through a 3/8 in NPT female inlet. An aluminium body and bowl resist corrosion in workshop environments. A screwdriver-adjustable mechanism lets operators set the feed rate for pneumatic tools that require internal lubrication. The unit is rated for a maximum flow of 75 cfm.
Sustained flow and pressure limits
At the rated 75 cfm the lubricator maintains consistent mist delivery up to 250 psi operating pressure. The aluminium construction handles continuous operation at temperatures up to 175 degrees F without deformation. A built-in sight dome and sight gauge allow visual confirmation of oil level and mist density during extended shifts. Flow direction is fixed left to right.
Intermediate duty series constraints
The Intermediate Duty series targets general-purpose air systems rather than heavy industrial cycles. Maximum operating pressure of 250 psi and flow of 75 cfm define the practical envelope; systems exceeding either value require a different lubricator class. California Proposition 65 warnings apply because the product contains chemicals identified by the state as carcinogenic and reproductive toxins.

Questions about this item
Does the 250 psi mist lubricator add noticeable heat or noise when it runs continuously?
The unit has no motor or moving parts; it simply meters oil into the air stream, so it generates no heat or sound of its own.
What fittings and supply line do I need to connect the 3/8 in NPT ports?
You need a 3/8 in NPT male fitting on each side and a compressed-air line rated for at least 250 psi and 75 cfm.
Will the aluminum body and PE adjustment screw hold up on a system that still uses older steel piping?
Yes — the aluminum body and PE screw are compatible with standard steel piping; just use thread sealant on the NPT joints to prevent leaks.
