 Double-lap
flares provide added-strength joints which are more resistant to
fatigue and provide a better seal than single-thickness flares.
Double-lap flares formed by PHI machinery and tooling are free of
cracks and pit marks. The joint is also designed so that the inside
surface of the flare has a larger diameter than the inside diameter
of the tube or pipe, and, therefore, does not interfere with flow
characteristics of the system.
Typical Applications: Thin-wall tubing connections that are
subject to shock, vibration, or high internal pressures such as
automobile brake lines and critical aircraft hydraulic lines.
