Overview
This 20-inch spiral wound gasket is engineered for critical sealing in high-pressure, high-temperature industrial piping systems. Designed to meet rigorous HG standards, it provides a robust and reliable seal for flanged connections operating up to 360 PSI. The construction combines a resilient graphite filler with durable 304 stainless steel windings, creating a seal that accommodates flange rotation and surface irregularities. Its D-shape configuration with integral inner and outer rings ensures precise alignment and prevents gasket blow-out or over-compression during installation, making it a dependable choice for demanding process environments.
