First, assemble the bite type pipe fittings
① most important aspects of pre-bite type pipe joint, direct impact on the reliability of the seal. Generally require a dedicated pre-filter. Small diameter joints can be pre-installed on the vise. In practice, as a parent with a joint, nut, ferrule can be pressed hydraulic testing machine onto the pipe. There are card sets straight pipe joints, card sets Straight turned head, sleeve tee pipe fittings and other types. I found that even in the same factory shipment, these types of connector body tapered hole depth is often not identical result is a leak, and this issue is often overlooked. The correct approach is to end what kind of pipe metric hydraulic hose fittings joint body, connecting the ends of the corresponding pre-installed with the same type of connector, which can maximize avoid leakage problems. ② pipe end should be flush. After sawing the pipe should be ground flush on the wheel and other tools, and deburring, cleaning with high-pressure air blowing before use. ③ When preinstalled, you should try to keep the coaxial tube and connector body, if the skew is too large will cause the tube seal failure. ④ preloaded force should not be too much of the inner edge of the card is just embedded in the tube wall sets, card sets should not have significant deformation. During hydraulic fittings pipeline connection, then the provisions of the tightening force assembly. ф6-1 card sets tightening force is 64-1 15n, 16фmmr 259n, ф18mm for 450n. If, at the pre-card sets severe deformation, will lose seal.
