Returning the brake lines to the car after banjo bolt leakage can be frustrating, but copper washers should only be used on each side of each bolt/screw that leak and should be brand new. Their flat surfaces should face against each bolt while their rounded surfaces face towards either brake line fittings or fittings.
Crush Washers
Crush washers are one of the most misunderstood and misapplied seals in automotive work. Used whenever threaded fasteners need to seal off liquid (oil drain plug being an example), crush washers are made of softer material than regular steel washers–usually copper alloy like brass–that deform under pressure to create an airtight seal against their mating surfaces, unlike regular steel washers which will simply make contact and stop. A standard steel washer cannot do this effectively and will simply make contact and stop — which could damage threaded fasteners as well as rubber drain plug boots over time.
Crush washers serve two primary purposes, both related to improving seal quality and reuse. The first reason is quite evident–a standard washer simply cannot bear up under the strain applied by tightening a drain plug or other fastener, deforming in response to this pressure.
Installing the proper type of crush washer when installing a drain plug or other banjo bolt is key, and proper orientation of its washer must also be considered; its flat side should face against the pan while its rounded side faces away from the bolt – otherwise leaks or stripping out of aluminum cases may occur when changing oil.
Torque should also be applied at an appropriate amount when installing drain plugs or banjo bolts, according to your service manual’s recommendation. While your washer can take more, overdoing it could damage threads of the drain plug and result in fluid leaking out from underneath it. Therefore, it’s wiser to read up on what pressure should be applied, before using an effective torque wrench to install your banjo bolts.
Threaded Washers
Washers are circular pieces of hardware designed to distribute the force of screws or nuts evenly across their surface, reduce friction, prevent corrosion and leakage, protect surfaces from damage, serve as spacers and provide relief in many other ways. Available in various sizes, shapes, materials and finishes – washers can make all the difference in any application and failing to use one can have disastrous results.
Flat washers are the most frequently encountered type of washer. Made from metal or plastic material, their thickness varies and they often include a central hole to accommodate fastener heads or larger openings to allow bolts through easily. Used most often to distribute force, correct hole sizes or provide support, flat washers provide vital components of fasteners.
Spring washers are another form of washers with left-handed helixes designed to bite into the underside of components they are bolted to and resist turning. Although suitable for soft surfaces like hardened metal, their raised edge could cause threaded components damage when used alone on hardened surfaces; for optimal use use a spring washer alongside another flat washer which isolates it and stops its raised edge from biting into parts which cannot turn.
Keyed washers and insulating shoulder washers are two other common forms of washers. Keyed washers feature an internal tab to stop bolts from rotating, making them popularly used in automobile shafts and cylinder heads. Meanwhile, insulating shoulder washers made of nylon, peek or plastic provide insulation against electrical current and can help protect screws.
Slotted “C” washers allow users to easily assemble and disassemble bolted joints without taking apart nuts, bolts and washer installations. Spherical washers automatically compensate for angular deviations between fastener head faces and nut faces; split ring washers use frictional force to keep bolted joints from loosening; their rings have been split apart with sharp edges at either end to help avoid bending.
Stainless Steel Washers
Washers might seem like innocuous items, but their impact is far reaching. From protecting surfaces from scratches to stopping items from rattling and helping keep screws tightened down tightly – not forgetting their potential role in helping prevent corrosion in humid and chemical-rich environments – stainless steel washers make a smart choice for multiple uses.
Stainless steel washers are thin metallic disks made out of stainless steel that come in various shapes and sizes to suit a range of applications. Most commonly they’re used with bolts and nuts to distribute the load that’s placed upon surfaces more evenly, helping prevent bolt surfaces from being damaged as quickly.
Metal washers can also serve as spacers when bolts are used in materials thicker than their heads, preventing too deep an intrusion from happening and potentially binding with it. Stainless steel washers are frequently employed as spacers in construction projects to ensure that bolt heads don’t penetrate too deeply into dense materials like concrete.
The type of fastener being used should determine which washer is required; not all washers may suit all bolts or materials. For instance, carbon-steel washers could be susceptible to corrosion in environments with high pH levels or water that contains chlorides; they might even cause galvanic corrosion if used with dissimilar metals. In contrast, stainless steel washers tend to corrode less often and can be used in any environment.
Progressive, transfer, compound and combination dies can all be used to mass produce stainless steel washers in mass quantities. Of equal importance is choosing which die will create each individual washer as this determines its shape and size.
Copper Washers
Copper washers are an economical and versatile fastener that provide numerous advantages across industries. Commonly used in plumbing and automotive applications for sealing purposes, copper washers also serve other uses that range from providing strong seal between components to being resistant against work hardening which means they can endure high levels of stress without becoming brittle or breaking under pressure.
These washers are constructed using copper, an extremely versatile metal known for its malleability and ductility, making it easy to form them into various shapes and sizes for different applications. In addition to being strong, copper also boasts excellent corrosion resistance and electrical conductivity properties that make these washers highly desirable.
Copper washers are highly sought-after marine-grade sealants due to their durability and resistance to corrosion, making them the go-to choice in saltwater environments. Their resistance means they can survive exposure to saltwater and sunlight as well as extreme temperatures – ideal for sealing fittings, joints, and connections in marine engines, plumbing systems, and hydraulic equipment.
Gas appliances often utilize their superior conductivity to prevent leaks from water pumps and other components, helping maintain consistent gas flows with no leaks or misfires. Electrical medical devices frequently rely on them as well due to being sterilized while still offering reliable conductivity.
Copper washers can be an indispensable asset when it comes to automotive maintenance and repair. Simply unscrew any bolt or hinge from its location, thoroughly clean away dirt or debris, lubricate with grease before reattaching. A copper washer will create a strong and secure seal around its threads while protecting them from damage while helping ensure smooth and efficient operations – an easy and cost-effective solution that protects against costly leaks or loose connections that might otherwise lead to expensive damage down the line.
