Airtac GL Lubricator GL300C08J
The AirTAC Airtac GL Lubricator GL300C08J is a genuine G-series air lubricator. It meters an oil mist into the compressed-air line so cylinders, valves and air tools downstream stay lubricated, with See datasheet ports and a pc oil bowl. A lubricator does not filter or regulate — it goes last in the line, after the filter and the regulator.

About the Airtac GL Lubricator GL300C08J
The GL300C08J is an AirTAC G-series air lubricator: its single function is oil-mist lubrication of a compressed-air line, with no filtering and no pressure regulation. This 300-size unit has PT 1/4 in ports (PT is the standard thread; G and NPT versions are order options) and a transparent PC bowl for easy oil-level checks. The J suffix means it is supplied without a mounting bracket, so it bolts straight to a manifold or machine plate. Maximum working pressure is 1.0 MPa (145 psi); working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The same lubricator family spans 200, 300, 400 and 600 sizes, with or without bracket and with PT, G or NPT threads, so you can match the unit to the line it feeds. AirTAC publishes flow as curves rather than a single rating; ask us and we will confirm the datasheet and sizing for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. A lubricator has no drain, no regulating mechanism, no gauge and no filter element, so none of those figures apply. Oil grade, bowl capacity, flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
Model Code: Airtac GL Lubricator GL300C08J
| GL300 | G-series air lubricator, 300 body — sets the port range. |
|---|---|
| C0 | Port size See datasheet. This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| (blank) | Mounting bracket included. A bracket ships by default; J orders it without. |
| (blank) | PT thread. PT is the default; G is BSPP and T is NPT. |
The lubricator has the shortest code of the six G-series subfamilies — size, port, bracket, thread. There is no drain, pressure-type, gauge or filtering-grade position. Example: GL300-10JG is a 300 body, PT3/8", no bracket, G (BSPP) thread.
Size Class
- GL200PT1/8" - PT1/4"
- GL300PT1/4" - PT1/2"
- GL400PT3/8" - PT1/2"
- GL600PT3/4" - PT1"
A larger body carries a larger port and passes more air. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GL600 uses an aluminium-alloy oil bowl; the 200, 300 and 400 bodies use PC.

Where the Airtac GL Lubricator GL300C08J Is Used
Wire-processing machines
Lubricates the pneumatic cylinders on cut-and-strip and terminal-crimping machines where the unit bolts straight to the machine plate.
Nutrunner assembly cells
Feeds lubricated air to compact nutrunners and screwdrivers on small assembly cells supplied through 1/4 in drops.
Robot gripper circuits
Sits in the 1/4 in line to robot gripper actuators, supplying oil mist where tight panel space rules out a bracket-mounted body.
Is the Airtac GL Lubricator GL300C08J the Right Lubricator?
Size the unit to the line - 200, 300, 400 and 600 step up in port and flow capacity; this 300 size carries PT 1/4 in ports for compact drops and small actuators. Thread is PT as standard, with G (BSPP) and T (NPT) as order options. The J in the code means no mounting bracket is included, so choose it only where you can mount the body directly. Flow is published as curves, not a single rating, so ask us to confirm sizing against your air demand before ordering.
Quick checklist
- ✓ Body size for your peak flow (See datasheet here)
- ✓ Downstream equipment actually needs oil
- ✓ Thread PT, G (BSPP) or NPT
- ✓ Bracket needed, or order with J
- ✓ Bowl material: PC, or aluminium on GL600
- ✓ Fit after the filter and regulator
Installation & Maintenance Notes
- check Fit last in the line: filter, then regulator, then lubricator.
- check Mount vertically, bowl down, following the airflow arrow.
- check Keep inlet pressure within 0.05 - 1.0 MPa.
- check Use only oil approved for pneumatic lubricators.
- check Keep the unit above freezing (-5 to +70 °C, unfreeze).
- check Check the oil level regularly; top up before it runs dry.
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. The oil mist travels downstream, so if any branch of the line must stay oil-free, take that branch off before the lubricator. We will confirm the recommended oil grade from the factory datasheet on request.
Airtac GL Lubricator GL300C08J FAQ
AirTAC publishes G-series flow as performance curves, not as a single rated figure, so no flow number is quoted here. Send us your line pressure, port size and downstream air demand, and we will confirm the curve and the sizing from the datasheet on request.
No. The J suffix means no bracket is supplied; the same model without J includes one. Use the J version when you mount the lubricator directly on a manifold, valve plate or machine surface.
