Elbow Union - W Hydraulic Fittings
An Elbow Union-W is a type of hydraulic fitting that connects two tubes or hoses at a 90-degree angle. It also has a union joint, which allows the two tubes or hoses to be easily disconnected and reconnected without the need for tools.
W series hydraulic fittings are a type of bite-type fitting that is designed to be used with spiral or braided hydraulic hoses. Bite-type fittings work by using a ferrule with sharp serrations on the inside to bite into the hose and create a seal. W series hydraulic fittings are one of the strongest types of bite-type fittings available, and they are commonly used in high-pressure hydraulic applications.Elbow Union W hydraulic fittings are a versatile and reliable type of fitting that can be used in a wide range of hydraulic applications. They are commonly used in construction equipment, agricultural equipment, and industrial machinery.

A single ferrule elbow union is a type of compression fitting that uses a single ferrule to create a leak-proof seal between the tube and the fitting body. The ferrule is a metal ring that is placed over the end of the tube and then compressed by the nut of the fitting. This compression creates a tight seal that prevents fluid from leaking out.
Single ferrule elbow unions are typically used in low-pressure applications, such as instrumentation and process control systems. They are also commonly used in hydraulic and pneumatic systems.
Here is a step-by-step guide on how to install a single ferrule elbow union:
90 degree stainless steel tube elbow unions are pipe fittings that are used to connect two tubes or pipes at a 90 degree angle. They are typically made of stainless steel, which is a durable and corrosion-resistant material. Stainless steel tube elbow unions are available in a variety of sizes and can be used in a wide range of applications, including:
