Connectable with TEMA series, 25,38,50,75,100 The coupling is a Swedish-made self-closing two-way coupling for high-pressure systems where quickly dissolving connections are required. The coupling is completely stainless steel with a plug-in nipple made of stainless steel and special steel. Perfect sealing through double O-rings. Vibrations that can cause Wear is eliminated by the insertion nipple being stored at both ends. Free flow area. Fuse ring against involuntary disconnection. Select the pressure eliminator on the coupling female and plug-in tap, or on the side, where there is a risk of pressure increase after disconnection. Pressure classes: 1/4"-450 bar 3/8"-350 bar 1/2"-300 bar 3/4"-280 bar 1"-250 bar
