SITEC hose fittings Germany SITEC model SITEC price

SITEC 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.

SITEC hose fitting applications

Hose fittings mainly include threaded connections, flange connections, quick-connect couplings, etc. Different types have different applications. The main components of metal hoses are made of austenitic stainless steel, ensuring excellent temperature resistance and corrosion resistance. Moreover, there are many metal hose fitting models. Specifications are mainly selected based on the inner diameter. For metal hose fitting models, the main difference lies in the meaning of certain threads, such as the common NPT, PT, G, etc., which have different meanings. Consumers should understand the significance of these fittings when purchasing and then select according to their needs. Different models correspond to different fittings. In fact, metal hose fitting models correspond to metal hoses, so attention should be paid to certain aspects during selection. First is the choice of connection form, generally including flange connections, threaded connections, and quick-connect couplings, which should be selected according to actual needs. The second aspect is pressure; collection and distribution hoses and fittings should be selected based on actual working pressure to ensure smooth operation. Also consider the pressure and temperature the metal pipe fittings can withstand, as well as the corrosiveness of the medium.

SITEC hose fitting installation

Cleaned pipelines should be formally installed and greased as soon as possible. Connect and tighten all pipe fittings section by section according to the printed matching marks. Note that the originally removed o type O-rings must be reinstalled. All piping fixtures must be secure and not loose. All oil supply lines can be connected to the distributor outlet and lubrication points after greasing. Metric general-purpose threads are indicated by uppercase M. Metric general-purpose threads are divided into coarse-pitch and fine-pitch threads based on pitch. Coarse-pitch thread markings generally do not specify the pitch, e.g., M20 indicates coarse-pitch thread. Fine-pitch thread markings must specify the pitch. General-purpose threads are used for connection and fastening between mechanical parts. Threaded connections mostly use coarse-pitch threads. Fine-pitch threads have slightly higher strength than coarse-pitch threads of the same nominal diameter and better self-locking performance. Pipe threads sealed by threads can prevent leakage without adding filler or sealant. 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 used under high temperature and high pressure conditions.

SITEC hose fitting precautions

Do not use hose quick-connect couplings for purposes other than fluid transfer. Do not use with fluids other than the applicable fluid. Do not exceed the maximum operating pressure during use. Do not use outside the specified temperature range to prevent deformation of sealing materials, which can easily lead to leakage. Do not manually strike, bend, or stretch to prevent damage. Do not use in environments containing metal powder or sand/dust. Quick-connect couplings can be used in harsh working conditions and ensure long service life. Accumulation of debris can cause poor performance or leakage. Do not disassemble quick-connect couplings.
