An IX seal ring is a metal sealing element designed for compact flange connections in accordance with the NORSOK L-005 standard. It is primarily used in offshore oil and gas, subsea pipelines, and high-pressure petrochemical applications where reliable, leak‑tight sealing is critical.
Kaxite offers IX seal rings in 316L, 625 (Inconel®), and 718 (Inconel®). Each grade is coated with PTFE in a distinct colour – grey for 316L, orange for 625, and green for 718 – for easy visual identification per NORSOK requirements.
The PTFE coating serves multiple purposes: it prevents galling between the ring and flange, reduces friction during installation, aids disassembly during maintenance, and provides colour‑coded identification of the steel grade, simplifying field inspection.
IX seal rings are designed for pressures up to 15,000 psi and temperatures ranging from -196°C to +450°C, depending on the material grade selected. For specific application requirements, please consult our engineering team.
