＊： Limit temperature range of materials does not indicate the regular service temperature range of the items.
Regular service temperature range will be differed by the shape and the application of the product.
＊＊： For NBR+PVC material, the alternative material is taken into account as PVC is designated as an environmentally harmful chemical.
