M/TCN - ALUMINIUM FILLER PLUGS M/TCNS - ALUMINIUM FILLER PLUGS WITH BREATHER HOLE M/TSN - ALUMINIUM DRAIN PLUGS -Hex head plugs, with or without hole for breather made from Aluminium alloy 11S. -Models M/TCN - M/TCNS comes marked OIL, M/TSN model comes blank. -FASIT 202 fiber gasket, oil resistant (aluminium flat washers are optionally available). -Available on enquiry methric threads. Code F KMF - BRASS FILLER PLUGS WITH FILTER KMV - BRASS FILLER PLUGS WITH VENT VALVE G = Fiber gasket S = Breather holes f = Air Filter V= One-way check valve -Threaded metal plugs made from brass, FASIT 202 fiber seal (aluminium washers available). -Two breather holes are located under the hex head, providing an adequate airflow capacity. -KMF model is equipped with a metal filter inside (filtration degree 200 microns) to avoid pollution of the oil. -The KMV version is used when venting of the reservoir is required, only in case of internal over-pressurization. -The pre-tensioned spring of the valve will allow the valve disc to be lifted from its seat at a pressure of 0.4 bar (±0,1), thus allowing the air to escape: when the pressure is reduced after venting, the valve will close and stop air to entering the reservoir it will also prevent oil overflow through the plug's valve due to oil movement whilst in the closed position. -These plugs are applied in gear reducers, gearboxes, bearing housings and transmission of all kinds. -P = airflow rate L/min, with reference to the model KMF. -Available on enquiry made in stainless steel.
