How to order Hose Fitting
Note:1.For use with braided hoses.2.If use with spiral hoses,the fifth number of hose fitting series change from "1" to "2",for example: from P26711-**-** to P26712-**-**

Hydraulic hose fittings are necessary when connect various conductors such as tubes, pipes, and hydraulic hoses in the hydraulic system. Most of connections pipe fittings have a male and female component to accommodate the connection and assist with the process of containing and directing the flow of fluid. Also it can prevent any leakages and maintain pressure in the hydraulic system. Consequently, hydraulic fittings need to be strong, versatile, and reliable to operate safely and effectively in their respective applications. So hose fittings typically adhere to strict standards which dictate fitting construction, dimensions, and pressure ratings. Our Pehel fitting factory are hose supplier and supplier different hydraulic fitting types(custom fitting, flare fittings,JIC fittings, NPT fitting, parker hydraulic fittings, push lock fittings, flared fitting, BSPP fittings, metric hydraulic fittings, bsp fitting, ptfe fitting, stainless steel fittings, SAE fittings, reusable hydraulic hose fitting, swivel pipe fitting).
1. Connection Type Fittings
Hydraulic fittings are attached via a number of different connection methods, each with its own conveniences and advantages.
2. Compression Fittings
Compression fittings include all types of fittings which use compressive force to connect the vessel to the fitting.

3.Crimp Fittings
Crimp fittings involve placing hose over a tubular end and crimping against it with a sleeve, ring, or crimp socket. These fittings typically require crimping tools or machines to make the connections.
4.End Fittings
End fittings provide specific surfaces for connecting vessels in hydraulic systems. Plain ends are fittings with surfaces which allow pipes or tubes to be connected by adhesive, solder, welding, or other permanent means. Welding, when done properly on compatible materials, provides a strong and reliable connection.
5.Flange Fittings
Flange fittings are rims, edges, ribs, or collars with flush surfaces perpendicular to the attached pipe or tube. These surfaces are joined and sealed via clamps, bolts, welding, brazing, and/or threading.
6.Push-to-Connect
Push-to-connect fittings have ends that are designed to accept tubing by pushing it into the end. These fittings typically disconnect via some type of collar retraction. These connections are convenient for sections of the system requiring frequent disconnection and reconnection.
7.Threaded Fittings
Threaded fittings have screw threads (built-in grooves) on their inner (female) or outer (male) surfaces designed to accept connections with matching threads. Threads which provide a simple connection but no seal are called straight threads. Tapered threads are designed to provide a tight seal for gases or fluids under pressure. Seal reliability can be improved by adding a coating or seal tape (Teflon). Especially precise threads are called "dry fit", meaning they seal without the need for an additional sealant, which is important in applications where sealant addition could cause contamination or corrosion. The thread size is measured and based on the inside of the vessel. Thread size standards include NPT (National Pipe Thread) and BSP (British Standard Pipe), though other standards exist and usage often varies by country and industry. Each standard corresponds to a particular number of threads per inch (TPI).
