Why Does a Spiral Wound Gasket Need a Colour Code?
The colour code for spiral-wound gaskets does matter! The industry standards require that spiral wound gaskets be colour-coded. This helps identify what the spiral wound gasket is made of quickly and easily. With spiral-wound gaskets, there are two distinct colours: the colour of the outside rim and the colour stripe along the rim. Using our colour guide below, you can see the different materials available.
In the oil and gas industry, you have likely seen these spiral wound gaskets before. The outside rim is usually yellow (304 SS), green (316 SS), or orange (monel). All these materials are particularly well-suited for this type of industry, as they seal at high temperatures and pressures. The rim stripe is usually grey (graphite) and is used in many different industries.
