They are extremely versatile and offer an excellent seal in a wide variety of applications. The Spiralwound is manufactured by wrapping alternating layers of thin metal and a soft gasket filler material such as flexible graphite or PTFE. The chevron-shaped profile of the gasket provides resilience and a "spring like" characteristic that enhances the performance of the gasket.   Leader Gasket manufactures spiral wound gaskets in the full range of metal alloys and fillers. The company manufactures strictly to the standards as set forth by ASME B16.20 (formerly API 601), DIN 2699 and British Standards. Large diameter gaskets, standard dimensions, as well as special shapes and sizes are all available. Color coding is standard for the Spiralwound gaskets made by Leader Gasket.

	LG-13 The LG-13 is the most common profile of Spiralwound gasket and used extensively in ANSI B16.5 flanges. The gaskets consist of a metal guide ring (or sometimes referred to as a centering ring) and a Spiralwound sealing element. This profile is normally used in raised and flat faced flanged. The outer ring is often made of carbon steel (painted or zinc plated to prevent corrosion) but can be made of alloys for higher temperature and more severe medium applications.
