A banjo fitting is a type of fluid transfer connector that does not require rotation – ideal for systems with limited space.
To install a banjo bolt, you will require a pair of calipers to measure its height and pipe diameter before selecting its head size.
Size
Manufacturer of hydraulic banjo fittings such as reducer tees, cross connectors, and elbows with features including high-pressure capacity, rust and corrosion resistance, and oil compatibility. Available in both inch and metric sizes to meet NFPA standards.
These fittings differ from other pipe threaded fittings in that they do not require rotation to tighten them, thus eliminating any risk of damage to both hose and bolt. In addition, their unique design enables pipe entries and exits at 90-degree angles, making accessing tight spaces much more straightforward.
Metric banjo hydraulic fittings have quickly become the go-to choice in the automotive industry and other machinery that use metric systems due to their greater precision and broader pressure range than their NPT counterparts. They’re often utilized for hydraulic power systems, power steering fluid, and brake caliper connections, among others.
Metric Banjo Fittings are a particular type of hydraulic fitting with a hollow screw bolt designed for connecting pipes or tubes, commonly used in automotive fuel and oil systems, hydraulic power system components, power steering fluid, brake caliper connections, and turbocharger oil feed systems. Due to their unique design, these fittings can withstand high-pressure levels without being bent or rotated and are easy to identify by their distinctive markings.
Material
Banjo fittings are typically constructed of brass, but other materials, including stainless steel, can also be used. Used primarily in high-pressure applications like hydraulic systems and other machinery operating under intense pressure, banjo fittings can withstand constant movement and vibration stress as well as any stress from continuous use.
These fittings can be found in various pieces of machinery. They’re often used to connect fuel lines in automobile engines and transfer fluids in other applications like marine gear and aircraft engines. You’ll even find them being utilized within hydraulic applications to connect hoses to components.
Some banjo bolts feature female or dual female ends, while others can be male-bodied or single-bodied. Manufacturers provide various sizes, body styles, and thread options; materials may include nickel-plated brass or aluminum; features may consist of solderable ring pieces that can be soldered onto the bolt itself, metal nuts with an O-Ring seal, or even bonded seals that eliminate crush washers for use in high-temperature areas as well as rubber and PVC hoses – improving reliability while making systems more adaptable.
Thread
Banjo fittings utilize a standard thread type that can be found across many bolt types. To accurately gauge this thread type, a common thread gauge can help identify whether it is okay, coarse, metric, or standard, as well as give torque specs specific to your application.
Banjo fittings typically utilize BSPP thread, though other thread types exist, such as JIC 37-degree flare connectors and ORFS connectors. Banjo bolts can connect different kinds of pipes, such as hoses and tubes.
Banjo bolts offer another critical benefit by being able to withstand high amounts of pressure. This makes them perfect for applications involving hydraulic systems as they’re easily installed with tight seals for tight sealing.
Banjo bolts come in several different sizes and applications. Common uses for them include connecting fluid lines such as brake and fuel lines to an engine, industrial machines, and automotive engines, or being found online – easy identification is often provided through their appearance; most banjo bolts appear like regular bolts with holes through them.
Design
Banjo fittings are made from stainless steel, an extremely tough yet easy-to-use material capable of withstanding extreme pressure. Their simple use makes them the ideal solution for automotive applications, with sizes and thread options that include both metric and BSPP threads – the latter more prevalent among European and Asian systems.
Banjo fittings can be identified by their hollow long end that attaches to the end of a hydraulic tube or pipe and an open back designed to fit over the body of a hollow screw when tightened into machinery. When drawn securely into machinery, when the hollow screw tightens into position, its hole lines up with that at the open round end of a banjo fitting allowing hydraulic fluid to pass freely throughout its assembly.
Zero-leak gold banjo fittings provide reliable resealing without washer dependence, unlike standard washer-dependent banjo hydraulic, pipe, and hose fittings, which are challenging to reseal reliably. Zero-Leak Gold fittings come equipped with dual metal-to-metal seals as well as elastomeric backup seals designed to minimize gaps between components when applying assembly torque.
Banjo-style connections also offer another distinct advantage: They allow hose or pipe connections to move away from the banjo bolt, helping reduce damage and enhance performance in tight spaces like car brakes and hydraulic systems and equipment. This design feature is particularly beneficial in familiar places.
