1. Standard Oilers for Clean, Dry Conditions:
Brass body and adaptor with 1/4" BSP
Brass body and adaptor with 1/4" API
The standard models are for use in all applications where normal atmospheric pressure exists within the plant or machinery.
2. Oilers for Use in Dirty or Wet Environments:
Model Description Code No
Series L Brass body and adaptor as series N 12-38120
but fitted with PVC skirt to protect the
Series P Brass body and adaptor fitted with PVC 12-38127
skirt, no breather hole but includes an
Series L is extensively used in adverse environmental conditions but where normal atmospheric pressures exist.
Series P is used as a back-up device to maintain a constant level in an oil bath on equipment where the primary lubrication is oil mist or air/oil systems and where a rise in oil level would cause a problem.
3. Oilers for Sub-atmospheric Conditions:
Model Description Code No
Series Q Brass body and adaptor with 1/4” BSP 12-38128
threads. This oiler has no breather
holes and is fitted with an external
balancing tube in line with the side port.
Series S Brass body and adaptor with 1/4” BSP 12-38129
threads. This valve is identical to the
series Q except the balance tube is at
90 to the side port.
Both series Q and series S models are used in applications where sub-atmospheric pressure exists in the bearing or gearbox.
If a conventional standard oiler was fitted, air at atmospheric pressure allowed in through the breather holes would force the oil out of the body. The fitting of a balancing breather tube allowboth the oiler and component to be in pressure balance.
4. Oilers for Direct Mounting:
Instead of having a conventional body,
the series E constant level oiler is
designed for mounting into the
customers equipment thus avoiding
external pipework. The cap and adaptor
are made from brass and the adaptor is
threaded 1” BSP:
This oiler can be fitted directly into the top of a sump, gearbox or bearing housing and the level adjusted to the height required.
It is ideal for maintaining a level and providing a visual indication of oil usage in very shallow and inaccessible sumps where it would be difficult to fit a standard bodied oiler at the required oil level.
Reservoirs are available in glass or polythene.
