Threaded plug with seal VSTI M16X1,5 ED

The professional VSTI M16x1,5 ED threaded plug with an internal hex socket has been designed for the permanent and hermetic closing of ports in advanced power hydraulic systems. This element is perfectly suited for machine bodies, valve blocks, manifolds, and actuators operating in harsh conditions. Thanks to the use of a precise metric cylindrical thread and an integrated ED-type sealing ring, the component guarantees reliable protection against working fluid leaks under high pressure. The manufacturing standard based on rigorous technical norms ensures full repeatability of installation and a long service life for the entire hydraulic unit.

Application and technical characteristics

The VSTI M16x1,5 ED plug is dedicated to working in 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 reaching up to 400 bar (40 MPa). The standard ED-type sealing ring (Eolastic) 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 passivated galvanized steel without harmful chromium Cr(VI), which guarantees high corrosion resistance, meeting strict environmental and industrial standards.

Why choose our components?

By choosing our components, you invest in elements meeting strict ISO and DIN standards, which translates into the reliability of high-pressure installations. Precise thread execution according to the ISO 9974 standard ensures a perfect fit in machine ports, eliminating the risk of damaging the internal thread in expensive bodies. The use of a hex socket facilitates application in tight workspaces where traditional tools cannot be used. Additionally, to comprehensively protect the system against contamination and loss of medium, it is worth checking our threaded plugs and caps, selecting appropriate bonded seals or stocking up on reliable individual O-rings, which guarantees the full hermeticity of every industrial installation.

Frequently Asked Questions (FAQ)

1. What is the maximum operating pressure for the VSTI M16x1,5 ED plug?

The VSTI M16x1,5 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 provides excellent static tightness, vibration resistance, and prevents oil leaks under high pressure.

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

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