Is the VKA Cap, Carbon Steel with Zinc-Nickel Coating compatible with DIN 2353 nut type M and suitable for high-corrosion environments?

Yes — the VKA Cap, Carbon Steel with Zinc-Nickel Coating is compatible with DIN 2353 nut type M and suitable for high‑corrosion environments. It’s specifically designed for DIN 2353 nut type M (24° cone, NBR O‑ring) and is offered in both light (L) and heavy (S) series for broad system compatibility. Made from carbon steel and finished with a 6–10 µm zinc‑nickel coating, it delivers excellent corrosion resistance — verified to withstand up to 720 hours in a salt spray chamber without visible damage — while providing a robust, leak‑free seal for demanding hydraulic applications.

Can the VKA Cap, Carbon Steel with Zinc-Nickel Coating withstand temperatures and pressures typical of heavy-duty hydraulic systems?

VKA Cap, Carbon Steel with Zinc-Nickel Coating Format — Yes. The VKA blind plug is manufactured from high-quality carbon steel with a 6–10 µm zinc-nickel coating and uses a 24° cone plus an NBR O-ring, making it suitable for heavy-duty hydraulic systems. Carbon steel provides the mechanical strength required to withstand typical hydraulic pressures, while the zinc-nickel plating offers excellent corrosion resistance (up to 720 hours in salt spray) for harsh environments. The NBR O-ring delivers reliable sealing across the common temperature ranges of hydraulic fluids (typically −30 °C to +100 °C), and the DIN 2353 design (compatible with M nuts, light and heavy series) ensures proper fit and leak-free operation under pressure. For extreme temperature or specialized fluid applications (very high temperatures, aggressive fluids, or ultra-high pressures beyond standard hydraulic ranges), verify specific system pressure and temperature limits and consider alternative materials or seals.
