Flare-O®
Benefits
- Twin seals for no-weep, no-leak protection
- Permits wide range of assembly torques to obtain a seal
- Design dampens effect of vibration
- Not affected by temperature change
- Ease of assembly using standard tooling and methods
- Utilizes standard machining surface finishes
- Increases variety of material selection for specific applications, since high torque is not a primary requirement
- Fittings can reassemble and reseal repeatedly
- Reduces scrap and overall system costs
- Interchangeable with existing standard fittings
- Reduces total mass of components
Applications
- Tapered Fittings (SAE 37°, 45° and All Others)
- Fittings for Standard Port Entries
- Adjustable/Indexable Fittings
- Tube-to-Port Connectors
- Flange Applications
- Low Torque Banjo Fittings (With Primary and Secondary Seals at Each Interface)
- Use in retrofit applications to eliminate leaks, weeps and associated maintenance costs
- Interchangeable with existing tube and port fittings at the OEM level
- Reduce maintenance and warranty costs, increase profitability, enhance reliability with FLARE-O®
Design Notes
Geometry of the taper results in unit loading of mating faces significantly higher than that of standard
fitting designs. The design also minimizes any gap which may occur at the interface due to pressures in excess
of design limits. Unit loading of the sealing surfaces is made even greater by the existence of the groove in
the male surface. Even if no O-ring were present, the groove design alone permits assembly torques to be
substantially reduced. The cross-sectional area of the O-ring groove is larger than the cross-sectional area
of the O-ring. This allows the O-ring to move in response to pressure differentials. The O-ring is not extruded
during assembly into the area between the mating surfaces to behave like a gasket. Instead, the O-ring
essentially behaves like a super-viscous fluid, which takes the shape of the cavity that holds it, enhancing the
seal. The O-ring acts as the back-up seal should the metal-to-metal seals on both sides of the O-ring groove fail.
