Pipe, Tunnel/Infrastructure, and Door & Window gaskets—manufactured to European standards, tailored to your drawings

Industrial Gaskets
for Pipes, Tunnels & Building Openings

Advanced Gasket Technology: Leak-TightUV/Ozone-ResistantChem & Microbe-ResistantEasy-Fit InstallStandards-Ready

Our Gasket Products includes:

  • Pipe Gaskets

  • Tunnel & Infrastructure Gaskets

  • Door & Window Gaskets

  • O-Rings & Round-section Gaskets

  • Expansion Joint Gaskets / Seals

  • Rubber Sealing Profiles

Pipe gaskets, tunnel & infrastructure gaskets, and door & window gaskets are our three essential sealing solutions across industries. Pipe gaskets ensure leak-free connections in pipelines for water, gas, and oil using durable materials like EPDM or PTFE. Tunnel and infrastructure gaskets provide watertight protection for tunnels and concrete structures under high pressure, while door and window gaskets enhance airtightness, soundproofing, and energy efficiency in modern buildings.

Gaskets Technical Insights

1-Material Selection Cheat-Sheet

Material Typical Temp. Range* Great For Avoid/Notes
EPDM −50 … +150 °C Potable water, steam bursts, ozone/UV, outdoor exposure Not suitable for oils/fuels; choose NBR/HNBR/FKM for hydrocarbons.
NBR (Buna-N) −35 … +120 °C Oils/fuels, hydraulic fluids, industrial greases Moderate weather/ozone resistance; check low-temp flexibility at low ACN grades.
Silicone −60 … +200 °C Extreme temperatures, food/medical contexts Lower tear strength; not ideal for dynamic abrasion.

*Ranges vary by compound/cure system; we’ll confirm per specification sheet at quote time.
