ERMETO hose fittings Germany ERMETO models ERMETO prices

ERMETO hose fittings are components in hydraulic systems used to connect pipelines or attach pipelines to hydraulic elements. This is a general term for connectors that can be assembled and disassembled in fluid passages. Main types include: welded, bite-type, crimped, and flared.

ERMETO hose fitting installation

During the handling and storage of rotary joints, avoid impacts and drops to prevent damage to interfaces and internal parts. Ensure concentric installation as much as possible to ensure proper operation of the rotary joint. When installing thread-connected rotary joints, pay attention to whether the thread direction of the inner and outer tubes corresponds to the rotation direction of the drum, and the thread directions of the inner and outer tubes should also be consistent. The connection between the rotary joint and the pipeline must use a hose; rigid connections are strictly prohibited. The inlet and outlet of the rotary joint should be connected directly to the hose as much as possible to reduce the auxiliary weight on the joint and extend service life. For the assembly of the inner tube, pay attention to dimensional fit and auxiliary support for weight. For internal-rotation rotary joints, a tolerance fit of H8/e7 is recommended for the fit between the inner tube and the joint. The support and anti-rotation of the rotary joint should be appropriate; generally, the rod diameter should be 2mm smaller than the anti-rotation hole to avoid affecting the free adjustment and compensation of the rotary joint. Various connection methods for connecting rotary joints to equipment (customers can set up various types of connection methods according to the specific structure of the equipment used).

ERMETO hose fitting principle

Quick-change couplings: one type with a check valve, and one type without a check valve. In applications with a check valve, the check valve end is connected to the air source. When disconnected, the check valve closes automatically; when connected, the pin at the movable end opens the check valve. Self-locking is achieved by embedding steel balls into grooves, while a "cone-cylinder" sleeve locks the steel balls in place.

Cleaned pipelines should be formally installed and greased as soon as possible. Tighten all pipe fittings segment by segment according to the printed matching marks. Note to install the originally removed o O-rings. All piping fixtures must be secure and not loose. All oil supply lines can be left to be connected to the distributor outlets and lubrication points after greasing. Metric general threads are denoted by uppercase M. Metric general threads are divided into coarse-pitch and fine-pitch general threads based on pitch. Coarse-pitch general thread markings generally do not specify the pitch, e.g., M20 indicates a coarse-pitch thread. Fine-pitch thread markings must specify the pitch. General threads are used for connection and fastening between mechanical parts. Coarse-pitch threads are mostly used for general thread connections. Fine-pitch threads have slightly higher strength and better self-locking performance than coarse-pitch threads of the same nominal diameter. Pipe threads sealed by threads can prevent leakage without adding filler or sealing material. Pipe threads sealed by threads have two connection forms: cylindrical internal thread with conical external thread, and conical internal thread with conical external thread. The former connection is sufficiently tight, while the latter is usually only adopted under high temperature and high pressure conditions.
