Single/Twin Ferrule Compression Tube Fittings(Fine-Lok^TM / Well-Lok^TM) - General Information

CONSTRUCTION OF Fine-Lok Tube Fittings


Fine-Lok Tube Fittings consist of three precision component such as Nut, Single Ferrule and Body

Fractional Fine-Lok Fittings
Finger tight Fine-LokFractional Tube Fittings.	Assembled Fine-Lok Tube Fittings after tightening the Nut 1 ¼ turn from the finger tight position

Metric Fine-Lok Fittings

CONSTRUCTION OF Well-Lok Tube Fittings


Well-Lok Tube Fittings consist of four precision component such as Nut, Back Ferrule, Front Ferrule and Body.

GAUGEABILITY

SEALEXCEL Fine-Lok/Well-Lok Tube Fittings are manufactured to very stringent tolerances to meet the Gaugeability to check the gap between Nut and Body Hex, this allows easy inspection for sufficient tightening of the Nut before a system is pressurized, which ensures maximum safety and reliability.
