Special Design Widely Used Male Elbow-WE-NPT Hydraulic Fittings for hydraulic cylinder parts

Product Description

Male Elbow-WE-NPT hydraulic fittings typically refer to hydraulic fittings with a male NPT (National Pipe Thread) threaded end and an elbow configuration. NPT thread is a widely used standard for pipe fittings in the United States and is characterized by its tapered thread design. However, in general, the Male Elbow-WE-NPT hydraulic fittings are designed to provide a 90-degree change in direction in hydraulic systems using NPT threads. They are commonly used in applications where a pipe or tubing needs to be connected at a right angle.

Installation instructions The nuts of ROKE hydraulic connectors are all silver plated and coated with our patented nano lubricating layer. Through this method, the installation torque can be controlled within a reasonable range. Especially in narrow spaces or suspended operations, installation is very easy. In order to assemble correctly, the assembly instructions should be followed. Improper assembly may cause malfunctions or damage safety.

1. Cut the tube： 1/2˚ angle tolerance to the tube axis is permissible. Tube cutter is not recommendable.

2. Lightly remove chips and particles from the inside and outside cut edges of tube. Bevel up to 0.2mm × 45˚ is permissible.
3. For tube bend, the minimum height from the straight pipe end to the bending radius must be at least twice the
height of the nut.
4. Lubricate thread and cone of the fitting body, ring and thread of nut.

Assembly
5. Slip nut and then ring onto the tube end. Ensure that the ring is placed correctly.
6. Screw nut manually onto fitting body until finger tight. Hold the tube against the shoulder in the cone of the fitting body.
7. Mark nut and tube for measuring the prescribed turns of the nut.
8. Tighten the nut 1 1/4 turns. Tube must not turn with tube. Stop edge of the ring limits over-tightening by increasing tightening torque.

Check & Final Assembly
9. Loosen nut and remove ring-mounted tube from fitting. And check if a visivle collar has formed on the pipe in
front of the first cutting edge. If not, tighten slightly more.
10. Insert the pre-assembled tube into the fitting.
While holding fitting body with a wrench, tighten nut approx. 1/4 revolution beyond the point of a clearly perceptible resistance.

Here are a few key points to consider when working with Male Elbow-WE-NPT hydraulic fittings: 1.NPT Thread Type: NPT threads are tapered and require the use of pipe sealant or thread tape to ensure a proper seal. It's important to ensure that the male NPT threaded end of the fitting matches the corresponding female NPT threaded component in your hydraulic system. 2.Thread Size: Pay attention to the thread size of the Male Elbow-WE-NPT fitting to ensure compatibility with the other components in your hydraulic system. The thread size is typically specified in inches and refers to the nominal diameter of the pipe or fitting. 3.Tightening Torque: When installing Male Elbow-WE-NPT hydraulic fittings, use the appropriate tightening torque to ensure a secure and leak-free connection. Over-tightening can damage the fitting or cause thread distortion, while under-tightening can result in leaks. Refer to the manufacturer's recommendations for the recommended torque values. 4.Sealing: Proper sealing is crucial to prevent leaks in hydraulic systems. Male Elbow-WE-NPT fittings often require the use of pipe sealant or thread tape on the tapered NPT threads to create a reliable seal. Follow the manufacturer's instructions to achieve an effective seal. 5.Application and System Requirements: Consider the specific requirements of your hydraulic system and the application in which the Male Elbow-WE-NPT fittings will be used. Ensure that the fitting materials and design are compatible with the hydraulic fluid, pressure, temperature, and other system parameters. Always consult the manufacturer's documentation, guidelines, or technical specifications for the Male Elbow-WE-NPT hydraulic fittings you are working with to ensure proper installation and compatibility with your hydraulic system.
