347SS octagonal ring joint gasket,
ASME B16.20 octagonal ring gasket,
347SS lens ring flange
The pressure and temperature depend on the combination of materials used.
Chemical resistance:The corrosion resistance depends on the selected ring material.
RTJ gaskets are available as standard in soft metal and in 304, 316 and stainless steels. Versions in other materials on request.
Style R ring type joints are manufactured on oval (2962/R) and octagonal profiles (2961/R).
Both styles are interchangeable in the modern flat bottomed groove.
Octagonal profile joints are interchangeable on flat bottomes groove flanges which have a 23 degree angle groove wall
- Metal-to-metal contact creates a reliable seal
- Suitable for extreme pressure and temperature requirements
- Certified quality (including surface hardness)

Programming interface ring Joint gaskets come in two fundamental sorts, an oval cross segment and an octagonal cross segment. These essential shapes are utilized in pressures up to 10,000 Rubber Seals and Gasket. The measurements are institutionalized and require uniquely notched spines. The octagonal cross segment has a higher fixing proficiency than the oval and would be the favored gasket. Be that as it may, just the oval cross segment can be utilized in the old sort round base notch. The more up to date level base furrow configuration will acknowledge either the oval or the octagonal cross segment. The fixing surfaces on the ring joint sections must be easily completed to 63 smaller scale inches and to be liberated from shocking edges, apparatus or babble marks. They seal by an underlying line contact or an edging activity as the compressive powers are applied.
