orfs hydraulic fittings
An O-Ring Face Seal (ORFS) is a fitting designed to eliminate leakage in hydraulic applications. In an ORFS fitting, a rubber o-ring is inserted into a circular machined groove in the fitting body. A tight seal is formed when the o-ring in the fitting is compressed against the flat face of a component. We developed ORFS hydraulic fittings with an aim to meet customers the diverse needs of products.

In the machining process

cutter Overview
In the machining process, sheet cutting methods are commonly used in hand-cut, hose adapters semi-automatic cutting machine and CNC cutting machine. Hand-cut flexible and convenient, but hand-cut

Cut quality is poor, dimension error, material waste and subsequent processing workload, while poor working conditions, low production efficiency. Semi-automatic contour cutting machine cutting machine

, Better quality cutting the workpiece, the cutting tool due to its use, is not suitable for single, small and large quantities of cutting the workpiece. Other types of semi-automatic cutting machine while lowering

Labor intensity, but its function is simple, only for some of the more regular shape cutting parts. CNC cutting manual and semi-automatic cutting mode relatively speaking, to be effective

To improve the efficiency of sheet metal cutting, cutting quality, double hose connector reduce labor intensity of the operator places. Some small and medium enterprises in our country and even in some large enterprises using hand-cut and

Semi-automatic cutting mode is also relatively common.

China's machinery industry steel usage has reached more than 300 million tons of steel cutting very large; With modern machinery industry, for cutting sheet metal work

For efficiency and product quality requirements also increased. CNC hydraulic ferrule cutting machine which is still very large market potential, market prospects more optimistic.
