The STECKO socket connectors category in the HYDRON online store includes steel adapters and connectors designed for threadless bonding of pressure hoses in the STECKO plug-in system. These connectors are equipped with sockets on one or both sides of the body, allowing for instantaneous, secure, and leak-proof connection of hydraulic plugs without the need to tighten nuts with a wrench. The connection is mechanically secured using a special staple (steel clip), which ensures the highest level of safety under high pressure. The STECKO system is a recognized standard widely used in underground mining plants, extraction machinery, and heavy industrial systems. The construction of socket connectors made of free-cutting steel with an anti-corrosion coating and an integrated O-ring seal with a Teflon ring guarantees failure-free operation in harsh operating conditions.

Advantages and technical properties of STECKO socket connectors

STECKO socket connectors from the HYDRON range stand out with parameters adapted to extreme hydraulic loads:

• Threadless and fast plug-in assembly: Pressing the plug into the socket and inserting the steel staple allows for a leak-proof connection in seconds, facilitating maintenance work in confined excavations.
• Double O-ring seal with a Teflon ring: The combination of a rubber O-ring with a Teflon backup ring ensures complete leak-tightness at operating pressures from 200 to 450 bar.
• High resistance to pressure and hydraulic surges: Made of high-quality free-cutting steel protected by zinc plating, it protects elements against mechanical damage and corrosion.
• Wide range of operating temperatures: The connectors are adapted to work at temperatures from -40°C to +100°C using standard NBR seals (limited to 90°C for continuous fluid operation).

Range of sizes and variants in the HYDRON store

In the HYDRON range, we have a full dimensional range of STECKO socket connectors adapted to standard internal hose diameters:

• Nominal DN sizes: Available variants include DN10, DN12, DN19 (DN20), DN25, DN32, and large transmission sizes DN51 (2 inches).
• Body geometry: Straight double-socket round connectors, 90-degree socket elbows, swivel variants with BSP male thread, and socket tees.
• Compliance with industry standards: Products meet PN-G32000 standards and are fully compatible with original mining supports and equipment.

Application in mining and heavy industry

STECKO socket connectors are widely used in powered roof support sections, longwall shearers and roadheaders, haulages, installations supplying HFA, HFB, HFC fluids, as well as in mobile construction machinery and forklifts where fast disconnection of oil lines is required.

Frequently Asked Questions (FAQ)

How is the connection secured in a STECKO socket connector?

After inserting the plug into the STECKO socket, a steel staple (clip) is inserted into the transverse holes of the body, which locks the plug collar and prevents it from sliding out under pressure.

Does the socket connector contain a seal inside the socket?

The O-ring seal along with the Teflon backup ring is placed on the plug part inserted into the socket, so that the socket face remains smooth and easy to keep clean.
