Powerful Lock Half-Union, Dual Compression Ring Type, Brass

Powerful Lock Half-Union, Dual Compression Ring Type, Brass

· A flareless type that can be connected by simply inserting the tube and tightening the nut — no special flare tools or brazing are required.
· The tube is compressed firmly by the effective plastic deformation of the rings. This is achieved by the interaction of the unique double rings, which produce a very strong resistance to pressure.
· The sealed parts of the main body are carefully finished to ensure high air-tightness despite using metal seals.
· Low tightening torque, small, and lightweight for easy attaching/removal.
· Tube sizes are displayed on the nut for easy visible size checking.
