An industrial hose is an assembly that consists of a hose, stem, ferrule, couplings, and fittings. In order to safely compress and deform such products to a specific hose length or diameter, two processes can be used: crimping or swaging. Though it may seem counterintuitive to change the physical composition of a hose, the swagging and/or crimping process is a critical part of the hose assembly.

For countless environments, vehicles, and systems, having the ability to detect the presence of a fire or flames is paramount for upholding safety. For a stark majority of fire detection technology, the detection of a fire is made possible through the detection of heat, particulate matter from smoke, or light from the flame. Depending on the application, certain methods of detection may not be optimal, such as detecting flame heat when hot pipes are present or detecting particle matter when other environmental substances are present. Flame sensors or flame detectors are an extremely advantageous option, capable of detecting flames in less than a second through optical means.

The evaporative emission control system (EVAP) is used in automobiles to keep fuel vapors inside the fuel tank and prevent them from entering the surrounding environment. This crucial system usually functions without issue, but if any problems do surface, such issues can lead to a frustrating check engine light. In the EVAP, one of the most critical elements is the purge valve. It is also one most prone to degradation and failure. In this blog, we will discuss everything you need to know about purge valves so that you may have a better understanding of the EVAP as a whole.

Fasteners are unique components that are found in countless applications, providing securing mechanisms for many assemblies. As such, they find use in a diverse set of industries including aviation, automotive, off road, and more. Coming in a variety of styles and types, fasteners are available in both simplistic and complex designs. With this in mind, this blog will cover quarter turn fasteners, a type of fastener that is often overlooked, but is incredibly useful.

Soldering is a process in which two or more objects are joined together by melting and placing a filler metal in a joint. It is the preferred method for securing copper pipes in plumbing or assembling electrical components in printed circuit boards (PCBs). While soldering is a strong and reliable way of joining materials together, it is not a permanent fix. In the case that you want to remove or disconnect a joint, you can simply desolder the soldered joint.

It is hard to imagine a modernized world without fasteners. These small, often unnoticed, components help bind every building, machine, and vehicle we see. Choosing the right fastener for your project is crucial and will vary based on the application. While there are several factors that one should keep in mind when dealing with fastener selection, this blog will focus on choosing the right material for the job.

Valves are common components within fluid systems, allowing for fluids to be isolated and regulated in terms of flow. Depending on the need of a system and the particular fluids that it is transporting, there are numerous valve types that one may use. The butterfly valve is a common variation, featuring quarter turn operations that are reminiscent of ball valves. Popular for their low cost, rapid operations, and varying sizes, butterfly valves find use in applications related to pharmaceutical operations, wastewater treatment, chemical and oil transportation, and more.

Losing power due to an unforeseen occurrence can affect countless industries, often resulting in a loss of production, revenue, and even life. As such, businesses and industries implement backup generators which serve to ensure that operations may continue even through emergencies. These backup generators are not always perfect, however, and they can fail if not maintained or used properly. As having backup generators onsite for fall-back is crucial for many, it is imperative that operators and facilities are well aware of load bank testing.

Aircraft fuel systems are complex and made up of many different components. While each aircraft may vary slightly in regard to individual parts, a few principal fuel systems are found on every plane. The size and demand of varying aircraft will determine the fuel system needed and the location of fuel tanks. Gravity feed systems and pump feed systems account for most fuel systems found on nearly every aircraft, ranging from personal to cargo planes.
