Is the Profile Seal DIN3869, NBR 85 Shore compatible with both metric and inch threads per DIN 3852‑11E for high‑pressure applications?

Yes. The Profile Seal DIN3869, NBR 85 Shore is compatible with both metric and inch threads per DIN 3852‑11E for high‑pressure applications. Its profiled geometry conforms to DIN 3869 to provide an exact fit with DIN 3852‑11E thread forms, and the premium NBR (85 Shore) material offers high resistance to pressure, wear and deformation, ensuring reliable, long‑lasting sealing performance in hydraulic and pneumatic high‑pressure systems.

Can the Profile Seal DIN3869, NBR 85 Shore maintain sealing performance under fluctuating temperatures and pressure spikes in hydraulic systems?

Yes. The Profile Seal DIN3869, NBR 85 Shore is engineered to maintain sealing performance under fluctuating temperatures and pressure spikes typical for hydraulic systems. Key points: - Material resilience: NBR (nitrile rubber) at 85 Shore provides high resistance to compression set, wear and deformation, helping the seal recover after pressure excursions and thermal cycling. - Pressure capability: The profiled geometry and DIN 3869 standard design ensure secure metal-to-elastomer contact for high‑pressure metric and inch thread connections (per DIN 3852‑11E), minimizing extrusion and leakage during spikes. - Thermal stability: While NBR has defined operating temperature limits, its robust construction and precise fit reduce seal movement and maintain contact under normal hydraulic temperature variations; this supports consistent performance across typical system ranges. - Durability: The combination of premium NBR and exact profile reduces maintenance needs and extends service life, preserving sealing integrity through repeated pressure and temperature fluctuations. Note: For extreme temperatures outside NBR’s recommended range or unusually high transient pressures, verify compatibility with system conditions and consider alternative materials or protective design measures.
