Learn when to choose graphite-filled spiral wound gaskets for reliable sealing in high-temperature, high-pressure, and corrosive industrial applications.

Non-rounded spiral wound gaskets provide superior sealing for irregular or non-standard flange geometries, offering enhanced reliability and leak prevention in critical applications where conventional round gaskets cannot achieve a precise fit.

Nuclear spiral wound gaskets rely on optimal material combinations to handle intense radiation, heat, and pressure. The best choices include Inconel or 316L stainless steel for the metal winding, paired with flexible graphite or mica fillers to deliver durable, leak-proof sealing in critical nuclear environments.

ASME B16.20 specifies the dimensions, materials, and markings for spiral wound gaskets used with ASME B16.5 and B16.47 flanges, ensuring reliable sealing in piping systems.

PTFE (polytetrafluoroethylene) rods are notoriously difficult to bond because of their extremely low surface energy and non-stick nature. Standard glues usually fail, but surface treatments like chemical etching or plasma activation, combined with specialized adhesives, can create a durable bond.

The maximum pressure rating for PTFE tubing depends on factors such as wall thickness, diameter, temperature, and tubing grade, with typical ratings ranging from a few hundred psi at elevated temperatures to over 1,000 psi at room temperature for thick-walled tubing.
