Learn how and when to remove this template message Flare fittings are a type of compression fitting used with metal tubing, usually soft steel, ductile soft copper and aluminum, though other materials are also used. Tube flaring is considered to be a type of forging operation, [1] and is usually a cold working procedure. Flared connections offer a high degree of long-term reliability and for this reason are often used in mission-critical and inaccessible locations. The tool used to flare tubing consists of a die that grips the tube and a mandrel that is forced into the end of the tube to form the flare by cold working. Further, AN fittings or those complying with subsequent standards and JIC fittings are not interchangeable for design-controlled applications due to differing quality standards.

Products Innovative Fasteners for Special Applications We welcome your custom design challenges as an opportunity to push the envelope and create the standards of tomorrow. Its use allows for simple and quick fluid coupling installation and eliminates possible FOD in critical applications, while still providing crucial reusability over the lifetime of the fluid coupling joint.

Configured to minimize impact to existing application components and envelopes, the B-Nut can be installed in applications without additional tooling. Barrel Nuts Barrel nuts minimize drilling and eliminate the need for long expensive bolts when attaching heavy structural members in high-tensile applications, such as hanging aircraft engines or attaching wings or tails to the fuselage.

Barrel nut retainers are sheet metal parts that typically clip on barrel nuts to facilitate their installation in holes and alignment with mating bolts. Fabricated in advanced aerospace alloys, barrel nut designs include floating or nonfloating, metallic lock or nonmetallic ring, tandem nuts with spreaders, spreaders that articulate, and barrel nuts with attached retainers or lanyards.

Bearing Locknuts Bearing locknuts are designed for shaft or spindle applications in aircraft engines, gearboxes and transmissions to provide a positive rotational lock under vibratory conditions and maintain precise torque pre-loads. The precision and effectiveness of this mechanical lock has made it the industry design standard. Bearing Locknuts are available in advance aerospace alloys with either internal or external threads, internal or external wrenching slots or holes, and metallic or nonmetallic locking devices in sizes from 0.

Expandable Diameter Fasteners Expandable diameter fasteners are custom-engineered to expand in a hole to prevent fretting. These unique fasteners can eliminate the need for expensive close tolerance machining or press fits. Typical applications include: aircraft engine mounting, helicopter blade attachment, mounting of anti-friction bearings, and redesigns requiring a tighter joint.

The heart of the fastener is the expandable bushing stack of alternating tapered split bushings. When a compressive force is applied to the ends of the bushing stack, the diameter of the fastener increases. When the force is relaxed, the bushings return to their original diameter, and the fastener can easily be removed and re-used.

The family of expandable diameter fasteners include: bolts, blind bolts, shafts, and cam-operated pins. Inserts for Sandwich Structure Inserts are potted or mechanically installed in sandwich material, like honeycomb, to allow fabrication of aircraft interior secondary structure including stow bins, galleys, and lavatories. Insert types include threaded or nonthreaded, through or blind, locking or nonlocking. Floating inserts feature a nut component that can move to compensate for screw misalignment.

Spacers are installed in structural applications, most typically in aircraft floors. Spacers are either one-piece or a two piece system of plug and sleeve. Often spacers are installed with epoxy under the flange to increase shear load carrying capability. Boss Adapters Shur-Lok makes several types of lockwireless boss adapters that will not rotate under extreme service conditions. The adapters provide reliable fluid line connections to engine housings, gearboxes, manifolds.

Ring locked boss adapters consist of a fitting with external serrations and a matching lock ring supplied as an assembly to simplify installation. Once the fitting assembly is threaded into the port and torqued to provide proper sealing, the lock ring is driven into the standard prebroached port to prevent the fitting from turning.

The unique port end configuration results in a lower stand-off that provides for the design of a compact boss. Shur-Lok B-Nuts are another type of lockwireless boss adapter in which the locking element is contained within the nut.

It installs in tight spaces without special tools. Shur-Lok boss adapters are designed for applications in fuel or fluid systems of aircraft, helicopter, and engines. Studs and Inserts Shur-Lok studs and inserts are designed for resistance to high torque-out and pullout loads. These products are ideal for the high fatigue and vibration environments of aero engines, gearboxes, turbo machinery, and military vehicles. They are available in a wide range of materials, finishes, and thread locking features.

Miscellaneous Fasteners Isolator mounts are designed to reduce vibration, noise and heat transfer to the interior of aircraft. These neoprene or silicone rubber and metal fasteners are typically installed between the exterior fuselage and interior aircraft passenger walls.

Types include nuts with thread lock or quick-release receptacles when frequent removal is required. Blind Inserts are installed from one side and are typically used in sheet metal applications where high-torque is required. Types include flush or plus flush heads, locking or nonlocking, carbon or stainless steel.

Shur-Lok has designed special inserts for a myriad of additional applications. Please check with us as to whether we already have an insert design that will fit your special requirement. Precision Machined Components and Assemblies Shur-Lok International processes all aerospace materials with particular expertise in machining and assembling engine and airframe structural components in high-alloyed steels, stainless steels, high-temperature-resistant steels, and titanium.
