The R.OL.TPV press-fit breather filler cap with vent valve is designed for reservoirs where a slight positive pressure needs to be maintained. The integrated one-way valve keeps the cap closed under normal operating conditions and only allows air to escape when the pressure inside the reservoir reaches approximately 0.20 to 0.25 bar. This helps limit air exchange with the surrounding environment.
