PERMA hose connector Germany PERMA model PERMA price

PERMA hose connectors are end-fittings, used as straight connectors to attach metal hoses to enclosures; they are detachable connection points between components and pipelines. They play an indispensable role in pipe fittings and are one of the two main components of hydraulic piping. Hose connectors are high-quality flexible pipes in modern industrial piping systems. They mainly consist of bellows, a wire braid, and connectors. The inner tube is a thin-walled stainless steel bellows with a spiral or annular shape, and the outer braid of the bellows is woven from stainless steel wire or steel strip according to specific parameters. The connectors or flanges at both ends of the hose match the connectors or flanges of the customer's pipeline. The bellows of the hose are formed by high-precision plastic processing of extremely thin-walled seamless or welded stainless steel pipes. Due to the elastic characteristics of the bellows profile, the hose has good flexibility and fatigue resistance, making it easy to absorb cyclic loads from various motion deformations, especially the ability to compensate for large displacements in piping systems.

PERMA hose connector classification

When disconnected: When the sleeve of the female body is moved to the other end, the stainless steel balls automatically roll outward, and the male body disconnects under the combined force of the valve springs in the male and female bodies; the valves in the male and female bodies close respectively, instantly blocking fluid flow. When connected: When the male body is inserted into the female body, the sleeve returns to its original position under the action of the spring, the steel balls roll and lock the male body tightly, and the valves in the male and female bodies push each other open, allowing fluid to flow; the O O-ring completely prevents fluid leakage. Disconnected: When the sleeve of the female body is pushed to the other end, the steel balls automatically roll outward, so the male body is removed; since neither the male nor the female body has valves, fluid flows out. When connected: When the male body is inserted into the female body, the sleeve is pushed back to its previous position by the spring force, causing the steel balls to lock, allowing fluid to flow; the O O-ring prevents liquid leakage. Disconnected: When the sleeve of the female body is moved to the other end, the stainless steel balls automatically roll outward, and the male body is pushed away by the reaction force of the valve spring, allowing the valve to close automatically to block fluid flow. When connected: When the male body is inserted into the side of the female body with the sleeve, the valve opens, causing fluid to flow; the gasket is pushed back to its original position by the spring force, and the stainless steel balls lock to ensure the male/female connection, while the inner gasket completely blocks fluid leakage.

PERMA hose connector applications

A bushing is a component widely used in domestic large-scale power plant supporting projects, seawater, steam, cold water, hot water, oxygen, drinking water, refrigeration, oil, gas, medical gas, sewage treatment projects, municipal engineering, chemical industry, oil refining, metallurgy, fertilizer, papermaking, pharmaceuticals, and other industries. Bushings are used when water pipes need to change diameter. For example, a DN15 water pipe needs to be reduced to a DN20 water pipe. The DN15 water pipe is a male-threaded pipe, connecting to the internal thread side of the bushing. The DN20 water pipe is a female-threaded pipe, connecting to the external thread side of the bushing. If the DN20 water pipe is a male-threaded pipe, a female-threaded reducer can be connected between the DN20 male-threaded pipe and the bushing. Threaded connections can conveniently connect to any water fixtures and valve meters. Industry. Often used in daily life to connect internal and external threads (teeth) of pipes to change the pipe diameter.

PERMA hose connector usage

The connection between hose connectors and hoses is generally completed using a hose crimping machine. First, cut the hose to the required size, then strip the outer layer of the hose to the measured dimensions, install the hose connector, and finally crimp it with the hose crimping machine. The specific steps are as follows: 1, select the appropriate hose and cut it to the specified length. 2, strip the outer rubber from both ends of the hose. 3, select the appropriate type of hose connector. 4, sequentially install the connector core (needs to be oiled) and the hose connector outer sleeve. 5, crimp with the crimping machine, paying attention to selecting the appropriate crimping amount. 6, after crimping is complete, clean the rubber debris from the inner wall of the hose, then install the dust cap, sealing ring, and retaining ring.
