Description
Screw it into the filler opening of a tank or gearbox: remove it to fill, and leave it in place so air can flow in and out as the level changes. The dipstick can be shortened to suit the tank depth. With a dipstick, the plug is for mineral oils only, not for water. For oil-hydraulic systems, a breather with air filter is recommended.
Pros:
- Air filter keeps dirt out of the tank
- Dipstick can be shortened to fit the tank depth
- Fill and breathe through one opening
- Large ribbed cap, screwed in and out by hand
Cons:
- Not for water - for water tanks, choose a version without dipstick

Filler and breather plugs for hydraulic tanks and other fluid reservoirs, also used as fill and vent ports on gearboxes.

The air filters retain particles of 50 to 60 µm; for oil-hydraulic systems, a breather with air filter is recommended. For mineral oils from -20 to +100 °C; versions without dipstick are also suitable for water.
