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

FUJIKIN

[Features]
· 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.

Elbow Half Union-Type, Ring Joint

FUJIKIN

Connection made by crimping the inner surface of the ring to the outer surface of the copper tube, eliminating the need for thread cutting or welding. Simply tighten the cap nut to connect.

Half-Union Ring Joints

FUJIKIN

[Features]

· Special tools, fire, adhesives, and others are unnecessary.
· You can remove and re-mount easily even after usage for storage, inspections or piping.
· Excellent corrosion resistance even when exposed to external atmosphere thanks to nickel plating of outer surfaces.
· Beautiful appearance produces aesthetic effect.
