The R.OL.TSV breather filler cap with check valve combines a filler cap, air filter and integrated check valve in one compact solution for oil and hydraulic reservoirs. Manufactured from high-quality Polyamide 66, it features an integrated air filter and a check valve that allows air to escape from the reservoir only. This relieves excess pressure while preventing dust, moisture and other contaminants from being drawn into the reservoir through the breather.
