The Felt Washer [5] is inserted in the Seal Sleeve [6]. The O-Ring [4] is provided around the seal sleeve to make closer contact between the felt washer and plunger (A) and also to increase the dust-resistance. Moving plunger (A) after mounting the felt washer can dislodge the felt washer. Hold Washer (F) [3] with your hand to prevent the felt washer from becoming dislodged when moving plunger (A).
