artafast fasteners are integrally bonded and vulcanized from rubber rings and metal rings. They are sealing rings used to seal threaded and flange connections, consisting of a metal ring and a rubber gasket. The metal ring is treated for rust prevention, and the rubber ring is generally made of oil-resistant nitrile rubber or fluororubber. Combined gaskets are available in metric and imperial sizes, with standards specifying the combination form of metal gaskets and rubber. Combined sealing washers are used for sealing threaded pipe fittings and plugs. They are generally used together with ferrule-type pipe fittings to seal oil ports, mainly for static face sealing at hydraulic valve pipe joint threaded connections. They are suitable for static face sealing at British and American standard imperial thread connections and French and German standard metric thread connections.

artafast fastener applications

A type of fastener with a flat circular ring shape. Placed between the support surface of bolts, screws, or nuts and the surface of connected parts, it serves to increase the contact surface area of the connected parts, reduce pressure per unit area, and protect the surface of the connected parts from damage. Another type, elastic washers, also serves to prevent nuts from loosening. Washers and circlips are elastic pads or locking washers that prevent bolt loosening. The working principle of locking washers is very simple. They consist of two washers. The outer side has radial cam surfaces, while the inner side has inclined tooth surfaces. During assembly, the inner inclined tooth surfaces face each other, and the outer radial cam surfaces engage with the contact surfaces at both ends. When the connected parts are subjected to vibration and the bolt tends to loosen, only relative sliding between the inner inclined tooth surfaces of the two washers is allowed, generating lifting tension, thereby achieving 103% locking.

artafast fasteners widely applied

Also used in faucets (valves) to cut off the flow of liquids or gases. Rubber or silicone gaskets can also be used to reduce fan vibration. Typically, the outer diameter of a washer is about twice the inner diameter. Nitrile rubber is the most commonly selected material for rubber gaskets due to its highest cost-performance ratio. The use of rubber gaskets is generally found in more advanced fields, such as aerospace and rocketry. However, their performance is excellent and can surpass many metal materials. Various types of fasteners can be seen on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters, and supplies. Their characteristics include a wide variety of specifications, diverse performance and applications, and a high degree of standardization, serialization, and generalization. Therefore, some people refer to fasteners that already have national standards as standard fasteners, or simply as standard parts.

artafast fastener features

Ensures that the clamping force of the connection is maintained under strong vibration, superior to fasteners that rely on friction for self-locking; prevents bolt loosening caused by vibration, eliminating related problems caused by loose fasteners; no special installation work is required, easy to install and disassemble; temperature changes will not cause the connection to loosen; durable; reusable. Improves the locking level through structural anti-loosening methods, offering higher safety performance; prevents loosening caused by vibration and dynamic loads; Easy installation without affecting installation drawing changes, and easy disassembly; loosening torque is greater than tightening torque; Locking effect is not affected by lubrication, and increased lubrication improves the anti-loosening effect; has the same temperature characteristics as standard bolts and nuts; can be reused a limited number of times.
