Overview

This DN250 spiral wound gasket is engineered for creating high-integrity, leak-tight seals in critical flange connections within industrial piping systems. It is constructed with a resilient stainless steel winding and a flexible graphite filler, all reinforced with sturdy inner and outer centering rings. This design ensures superior performance under high pressure, thermal cycling, and in corrosive service environments. Each package contains two gaskets, providing a convenient supply for maintenance or installation projects.

Key Features

Manufactured to meet recognized industry standards for dimensional consistency and performance. Robust 304 stainless steel inner and outer rings provide structural stability and prevent gasket blow-out. Flexible graphite filler offers excellent sealing across a wide temperature range and compensates for flange surface irregularities. Spiral wound design provides inherent resilience to handle system vibration, pressure surges, and thermal cycling. Suitable for high-pressure applications with a pressure rating of PN25 (approximately 363 PSI). 304 stainless steel construction ensures strong resistance to corrosion and oxidation.
