Brass Double Compression Ring Model, Powerful Lock (Half Union)

FUJIKIN

[Features]
・ Since it is a flareless type, it can be connected simply by inserting the tube and tightening the nut, so special tools such as flare tools and fire are not required
・ Due to the mutual interlocking action peculiar to the double ring, the ring is effectively plastically deformed and the tube is firmly compressed, resulting in extremely high pressure resistance
・ The body seal part has a fine super finish, so it is highly airtight despite the metal seal method
・ Light tightening torque, small size, lightweight, and easy to put on and take off
・ Since the tube size is displayed on the nut, you can check the size at a glance

Powerful Lock Gauge Union, Rc Thread, 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.
