Threaded plug with ED seal VSTI M18X1.5

The professional VSTI M18x1.5 ED threaded plug with an internal hex socket is designed for durable and hermetic sealing of ports in advanced power hydraulic systems. This element is perfect for machine bodies, valve blocks, manifolds, and actuators operating in difficult conditions. Thanks to the use of a precise cylindrical metric thread and an integrated ED-type sealing ring, the component guarantees reliable protection against high-pressure working fluid leakage. The manufacturing standard based on rigorous technical norms ensures full repeatability of assembly and long life of the entire hydraulic joint.

Application and technical characteristics

The VSTI M18x1.5 ED plug is dedicated to stationary and mobile hydraulic systems where the working media are mineral oils, synthetic oils, and water-glycol based fluids. The construction is characterized by high resistance to nominal pressures up to 400 bar (40 MPa). The standard ED-type (Eolastic) sealing ring made of NBR nitrile rubber maintains full flexibility and tightness across a wide range of operating temperatures, while optional FKM fluorocarbon rubber variants allow for operation at higher temperatures and in contact with aggressive chemical media. The body of the element is manufactured from galvanized passivated steel without harmful Cr(VI) content, which guarantees high corrosion resistance, meeting strict environmental and industrial standards.

Why choose our components?

By choosing our components, you are investing in elements that meet strict ISO and DIN standards, which translates into the reliability of high-pressure installations. Precise thread execution according to ISO 9974 ensures a perfect fit in machine ports, eliminating the risk of internal thread damage in expensive bodies. The use of a hex socket facilitates application in tight work spaces where traditional tools cannot be used. Additionally, to comprehensively protect the system against contaminants and medium loss, it is worth checking our threaded plugs and caps, select appropriate metal-rubber washers or replenish stock with reliable individual O-rings, which guarantees full hermeticity of every industrial installation.

Frequently Asked Questions (FAQ)

1. What is the maximum working pressure for the VSTI M18x1.5 ED plug?

The VSTI M18x1.5 ED plug is designed to operate at a nominal pressure (PN) of 400 bar (40 MPa), which fully covers the requirements of standard and high-pressure power hydraulic systems.

2. What characterizes the ED-type seal used in this plug?

The ED-type seal (Eolastic) consists of an elastomeric ring with a special cross-section, which undergoes controlled compression in the cylindrical port during screwing. This ensures excellent static tightness, vibration resistance, and prevents oil leaks under high pressure.

3. Can the NBR sealing ring be used at higher temperatures?

The standard NBR nitrile rubber ring is designed for operation in moderate temperature ranges. For installations requiring continuous operation at higher temperatures or with chemical media, it is recommended to use an optional FKM fluorocarbon rubber seal.
