Hydraulic Fitting Types

Hydraulic hose fittings can be one of two types permanent or reusable.

Hydraulic fitting types. Various types of fitting allow the designer to change the flow of the fluid to split the flow of the fluid or to elevate the lines. Compression fittings include all types of fittings which use compressive force to connect the vessel to the fitting. Parker s comprehensive range of hydraulic fittings fulfills todays application requirements as well as state of the art safety and quality needs. To attach a crimped fitting you will need crimping or swaging equipment.

Below we ve compiled a hydraulic hose fittings chart describing some of the more common fitting sizes and types currently in use by pipefitters and other professionals. This section is intended as an aid to identifying the most popular threads on hydraulic. The hydraulic systems alone use countless different types of fittings and adapters with different sealing methods and thread forms. 2 were developed as an improvement over pipe fittings many years ago and probably remain the design used most often in hydraulic systems.

Permanent or crimped hydraulic fittings are widely used in the fluid power industry because they are easier and quicker to attach than reusable fittings. While the sealing method can often be distinguished by appearance thread forms all seem to look the same making it difficult and time consuming to identify them when equipment modifications or repairs are needed. Use these guides when identifying hydraulic fittings including drawings dimensions and connection instructions for bsp sae npt and more.

Our fittings are specifically designed to perfectly match with the respective hose types for superior service life and leak free operation. Within the hydraulic system these fittings seal fluid using either all metal fittings that use metal to metal contact or compressed seal o ring fittings. Tightening the assembly s nut draws the fitting into the flared end of the tubing resulting in a positive seal between the flared tube face and the fitting body. Types of hydraulic fittings to connect tubes pipes hoses valves and other elements almost every hydraulic system needs the use of fittings.

Hydraulic fittings are attached via a number of different connection methods each with its own conveniences and advantages. Crimped fittings are also more reliable.
